Mouse configuration in macOS
24th August 2024Now having a new location from which I can work, I acquired an all-in-one desktop computer for use while there. While tempted by an HP option that runs Windows, I ended up choosing an iMac instead. That gained me extra disk space and more memory at a cost. Having UNIX-style command line capability was another attraction. After living with the Windows terminal for a while, its limitations were all too apparent to me.
While I started off desktop computing on a Macintosh Classic and having owned a MacBook Pro in the more recent past, there still was a learning curve. One of these related to the configuration of the mouse supplied with the system. Whatever about only having one button and needing to learn gestures, it was the speed at which the pointer goes that really got me reaching for my more usual Evoluent. Even so, the subsequent discovery of LinearMouse makes things much more bearable once all the requisite permissions were assigned.
Getting the Evoluent configured to my liking needed another third-party application: USB Overdrive. If Evoluent's own software fitted the bill, that would have done. However, they have done some finger pointing at Apple instead of updating it to work with the latest Mac technology. There may be truth in the accusations, but it is striking that another piece of software works when theirs does not. Nevertheless, the other option worked once it got the permissions to detect the hardware. Then, it was a matter of working out which button was which on the mouse, so I could have them assigned as I wished.
After that, I could settle into the new system and get used to its idiosyncrasies. Adding Parallels got me a Windows 11 virtual machine for business compatibility, while I got going with setting up some automation using the macOS terminal. All is becoming more settled than working out of a laptop.
Needing third-party software does have a catch, though: underlying changes to macOS could scupper things. It was the sort of thing that made me move away from GNOME Shell as my Linux desktop. The extensions on which I was depending kept getting obsoleted by every new release. It is something to watch, even if macOS evolves less dramatic than GNOME 3 in its various forms.
Restoring the menu bar on GNOME Terminal in a GNOME Shell session
25th July 2020By default, a GNOME Terminal instance does not display a menu bar and that applies not only in GNOME Shell but also on the Cinnamon Desktop environment. In the latter, it is easy enough to display the menu bar using the context menu produced by right-clicking in the window before going to Edit > Preferences and ticking the box for Show menubar by default in new terminals in the General section. After closing the Preferences dialogue, every new GNOME Terminal session will show the menu bar.
Unfortunately, it is not so easy in GNOME Shell, though the context menu route does allow you to unhide the menu bar on a temporary basis. That is because the requisite tick box is missing from the Preferences dialogue box displayed after navigating to Edit > Preferences in the menus. To address, you need to execute the following command in a terminal session:
gsettings set org.gnome.Terminal.Legacy.Settings headerbar false
This change permanently adds the menu bar and includes the previously missing tick box, which is selected when necessary. Although GNOME Shell has a minimalist design in some aspects, making this function difficult to access seems excessive.
Suppressing Update Notifier messages in Ubuntu GNOME 14.04
18th July 2014Even though I use only the command line for system updates, I still received system restart messages after kernel updates. Though these can be helpful, I prefer to restart my system on my own schedule, especially when running processes I don't want to interrupt.
In Ubuntu GNOME 13.10 and earlier, these messages didn't appear. I wanted to return to a notification-free experience. The Update Notifier application causes these messages, but removing it significantly impacts the system, making that approach impractical.
The application starts automatically at boot but doesn't appear in Startup Applications Preferences (launched via gnome-session-properties). This is because the NoDisplay flag in its autostart shortcut located in /etc/xdg/autostart/ is set to true. To make it visible, you need to set this flag to false.
The following command will reveal all hidden startup applications (note that the command is split across two lines for display purposes, and you may need to adjust quotes when executing it):
sudo sed -i 's/NoDisplay=true/NoDisplay=false/g'
/etc/xdg/autostart/*.desktop
The sed command changes NoDisplay=true to NoDisplay=false in all desktop files, revealing hidden entries in Startup Applications Preferences. This allows you to disable the Update Notifier. While deleting the desktop file would be more permanent, this solution works well as it stops restart notifications. Since I regularly update my system and shut down daily, updates are applied automatically, and everything functions properly.
Fixing Background Image Display in GNOME Shell 3.10
2nd May 2014On upgrading from Ubuntu GNOME 13.10 to Ubuntu GNOME 14.04, a few rough edges were to be noticed. One was the display of my chosen background image: it was garbled. Later, I discovered that there is a maximum width of 2560 px for background images in GNOME Shell these days and that things get messy beyond that.
In my case, the image width was around 6000 px, and I was used to it getting resized in GNOME Shell 3.8 and its predecessors. It appears that the functionality got removed after that though, so the workaround of manual image resizing in the GIMP needed to be employed. Though having big images open in memory creates an additional overhead, not handling them very well at all looks like a bug caused by setting 2560 px as a maximum screen width for the GNOME Shell panel and the complete removal of Nautilus from desktop rendering duties. Let's hope that sense is seen with ever larger screen sizes and resolutions coming our way.
It's the sort of thing that did get me looking at adding on Cinnamon 2.2 for a while before setting background image scaling using the indispensable GNOME Tweak Tool was discovered. LinuxG.net has a useful tutorial on this for anyone with such an adventurous streak in them. For now though, I am OK with my set-up but the GNOME project's focus on minimalism could affect us in other ways, so I can see why Clem Lefebvre started the Cinnamon one primarily for Linux Mint and the desktop environment is appearing elsewhere too. After all, Gedit lost its menu bar in GNOME 3.12 so it's just as well that we have alternatives.
Update 2014-05-06: It appears that the desktop image bug that afflicts GNOME Shell 3.10 got sorted for GNOME Shell 3.12. At least, that is the impression that an Antergos instance in a VirtualBox virtual machine gives me.
Surveying changes coming in GNOME 3.10
20th October 2013GNOME 3.10 was released last month, but I only saw it when it appeared in the Arch and Antergos repositories. Despite stability risks, this showcases a strength of rolling distributions: they let you see the latest software before others. Otherwise, you might need to wait for the next Fedora release to view GNOME updates. This delay isn't always negative, as Ubuntu GNOME typically uses the previous version. Since many GNOME Shell extension developers don't update until Fedora includes the latest GNOME in a stable release, this approach ensures the desktop environment is well established before reaching Ubuntu. Debian takes this further by using a stable version from years ago, which has merits for system reliability.
As I regularly use GNOME Shell extensions, I'm interested in which ones still work, which need tweaking, and which no longer function. The main change in the top panel is the replacement of separate sound and user menus with a single combined menu. Extensions that modified the user menu now need reworking or abandoning. The GNOME project has adopted an irritating habit similar to WordPress, with frequent API changes that break extensions (or plugins in WordPress). However, GNOME should copy WordPress's approach to documentation, particularly for the API, which is barely documented anywhere.
GNOME Shell theme developers face challenges too. When I used Elementary Luna 3.4, a large border appeared around the panel, so I switched to XGnome Enhanced (found via GNOME-Look.org). The former theme is no longer maintained as its developer has stopped using GNOME Shell. Perhaps someone else could take it over, since it worked well until version 3.8. The new theme works well for me and will be an option if I upgrade to GNOME 3.10 on one of my PCs in the future.
Returning to the subject of extensions, I tested the included Applications Menu extension, which has improved stability and looks very usable. I no longer need to wait for the Frippery equivalent to be updated. The GNOME Shell backstage view hasn't changed much since 3.8, which may disappoint some, but the workaround works well. Several extensions I use frequently haven't been updated for GNOME Shell 3.10 yet. After some success before a possible upgrade to Ubuntu GNOME 13.10 and GNOME Shell 3.8 (though I'm staying with version 13.04 for now), I tried to port some of these to the latest interface. Below are my updated extensions, which you can use until they're officially updated on the GNOME Shell Extensions website:
GNOME 3.10 brings other modifications beyond GNOME Shell, which is mainly a JavaScript construction. Application title bars continue to be consolidated in GNOME applications, with a prominent exit button now appearing. You can still apply the previously mentioned modifications to Nautilus (also called Files), many of which work with other applications like Gedit. Gedit now includes useful 'x of y' numbering for search results, showing the current match number and total matches. The GNOME Tweak Tool has been overhauled, but no longer includes the setting for showing folder paths in Nautilus. To enable this feature, open dconf-editor, navigate to org > gnome > nautilus > preferences and tick the always-use-location-entry box.
The GNOME project continues on its path established a few years ago. While I wish GNOME Shell were more mature, significant changes are still coming, making me wonder when this will stop. This might be the result of introducing a controversial experiment when users were content with GNOME 2. Fedora 20 should bring more updated GNOME shell extensions. Antergos provides a good way to see the latest GNOME version if it remains stable. Cinnamon fans may be happy that Cinnamon 2.0 is another desktop option for the Arch-based distribution, one that I may discuss this further once the Antergos installer stops failing at package downloads. I'm setting up a separate VM to examine Cinnamon because it destabilised GNOME during a previous review.
A look at Ubuntu GNOME 13.10
12th October 2013With Ubuntu GNOME 13.10's final release approaching, I decided to try the beta version to see what's coming. However, I accidentally downloaded and installed the 64-bit edition of 13.04 in a VirtualBox virtual machine. My plan to update this to the upcoming release failed due to instability, so I couldn't test an in-place upgrade to 13.10. Originally, I had intended to use this command:
gksu update-manager -d
However, I found another one when considering how Ubuntu Server might be upgraded without the GUI application that is the Update Manager. To update to a development version, the following command is what you need:
sudo do-release-upgrade -d
To upgrade to a final release of a new version of Ubuntu, drop the -d switch from the above to use the following:
sudo do-release-upgrade
There is one further option that isn't recommended for moving between Ubuntu versions, but I use it to get updates, such as new kernel subversions that are released:
sudo apt-get dist-upgrade
Rather than trying out the above, I downloaded the latest ISO image for the beta release of Ubuntu GNOME 13.10 and installed onto a VM that instead. Though it is the 32 bit version of the distro that is installed on my main home PC, it has been the 64 bit version that I have been trying. So far, that seems to be behaving itself even if it feels a little sluggish, but that could be down to the four-year-old PC that hosts the virtual machine. For a while, I have been playing with the possibility of an upgrade involving an Intel Core i5 4670K CPU and 16 GB of RAM (useful for running multiple virtual machines at a time) along with any motherboard that supports those, so looking at a 64-bit operating system has its uses.
The Linux kernel is 3.11, but that's not my main concern. Neither am I worried about LibreOffice 4.1.2.3 being included while GIMP (version 2.8.6) wasn't, since it can be added easily. What drew me to explore the upcoming release was the move to GNOME Shell 3.8, as I rely on many extensions. Like WordPress and its plugins, GNOME Shell has a difficult relationship with extensions, and I wanted to see which still worked. The backstage application view has changed. Now you either see all installed applications or must type the name of the one you want. Losing the categorical view from GNOME Shell 3.6 is a backward step, and I hope version 3.10 brings it back. Although you can add categories, the result is inferior to the original. Users shouldn't need to modify system internals for such basic functionality. With all these constant changes, it's unsurprising that Cinnamon has become independent with version 2.0, and that Debian considered not using GNOME for its latest version (7.1 at the time of writing, which wisely chose GNOME Shell 3.4).
Having had a look at other distribution that already have GNOME Shell 3.8, I knew that a few of my extensions worked with it. The list includes Frippery Bottom Panel, Frippery Move Clock, Places Status Indicator, Removable Drive Menu, Remove Rounded Corners (not really needed with the GNOME Shell theme that I use, Elementary Luna 3.4, but I retain it anyway), Show Desktop Button, User Themes and Ignore_Request_Hide_Titlebar. Because of the changes to the backstage view, I added the Frippery Applications Menu instead of the Applications Menu because I have found that to be unstable. Useful new discoveries have included Curtains Up and GNOME Shell Open Terminal, while Shell Restart User Menu Entry has made a return and found a use this time around too.
There have been some extensions that were not updated to work with GNOME Shell 3.8 that I have got working. In some cases, it was as simple as updating the metadata.json file for an extension with new version numbers of 3.8 and 3.84 to the list associated with the shell version property. All extensions are to be found in the .local/share/gnome-shell/extensions location in your home directory, and each has a dedicated file containing the aforementioned file.
With others, it was a matter of looking in the Looking Glass (execute lg in the box that ALT + F2 brings up on your screen to access this) and seeing what error messages were to be found in there before attempting to correct these in either the extensions' extension.js files or whatever JavaScript (*.js) file was causing the problem. With either or both of these remedies, I managed to port the four extensions below to GNOME Shell 3.8. In fact, you can download these zip files and install them yourself to see how you get on with them.
Advanced Settings in User Menu
There is a Remove Panel App Menu that works with GNOME Shell 3.8, but I found that it got rid of the Places menu instead of the panel's App Menu, so I tried porting the older extension to see if it behaved itself and it does. With these in place, I have bent Ubuntu GNOME 13.10 to my will ahead of its final release next week, which includes customising Nautilus too. Other than a new version of GNOME Shell, it looks as if it will come with less in the way of drama and a breather like that is no bad thing given that personal computing incessantly remains in a state of flux these days.
Dealing with the Lack of Categories in the Application Overview Screen for GNOME Shell 3.8
10th July 2013Browsing through installed applications on computer systems is something that I find useful. While this is usually straightforward, some developers have replaced traditional menus with search boxes. GNOME Shell 3.8 has fallen into this trap. You can add the Applications Menu extension from GNOME Shell Classic, which I've tried, but it sometimes freezes the desktop session, so I don't recommend it.
However, there is a setting that brings back those application categories in the overview screen, and it can be set using dconf-editor. After opening up the application, navigate to org > gnome > shell using the tree in the left-hand panel of the tool. Editing the app-folder-categories entry in the right-hand panel is what adds the categories back for you. The default is ['Utilities', 'Sundry'] and this needs to be changed to ['Utilities', 'Games', 'Sundry', 'Office', 'Network', 'Internet', 'Graphics', 'Multimedia', 'System', 'Development', 'Accessories', 'System Settings', 'Other'].
After making these changes, the application overview screen displays categories in a new layout. Application icons appear in the middle, with categories listed on the right side. Clicking a category opens a panel showing applications within that category, which can then be closed. Navigating through categories requires opening and closing different panels. While the interface behaviour has changed, the core functionality remains, and I've heard GNOME Shell 3.10 will further refine this system.
For those wanting to exit all of this and get something like the old GNOME 2, it is possible to add the Classic Session. In Fedora 19, it's a matter of issuing something like the following command:
sudo yum -y install gnome-classic-session
In reality, this is a case of adding a number of extensions and changing the panel colour from black to grey, but it works without needing the category tweak that I described above. The Application Menu extension does need more stability hardening before I'd trust it completely, though. There's no point having a nicer interface if it's going to freeze up on you too often.
Sorting a kernel upgrade error in Linux Mint 13
30th November 2012Linux Mint 14 may be out now, but I'll be sticking with its predecessor for now. Being a user of GNOME Shell instead of Cinnamon or Mate, I'll wait for extensions to get updated for 3.6 before making a move away from 3.4 where the ones that I use happily work. Given that Linux Mint 13 is set to get support until 2017, it's not as if there is any rush either. Adding the back-ported packages repository to my list of software sources means that I will not miss out on the latest versions of MDM, Cinnamon and Mate anyway. With Ubuntu set to stick to GNOME 3.6 until after 13.04 is released, adding the GNOME 3 Team PPA will be needed if 3.8 arrives with interesting goodies; there are interesting noises that suggest the approach taken in Linux Mint 12 may be used to give more of a GNOME 2 desktop experience. Options abound and there are developments in the pipeline that I hope to explore too.
However, there is one issue that I have had to fix which stymies upgrades within the 3.2 kernel branch. A configuration file (/etc/grub.d/10_linux) points to /usr/share/grub/grub-mkconfig_lib instead of /usr/lib/grub/grub-mkconfig_lib so I have been amending it every time I needed to do a kernel update. However, it just reverts to the previous state, so I thought of another solution: creating a symbolic link in the incorrect location that points to the correct one so that updates complete without manual intervention every time. The command that does the needful is below:
sudo ln -s /usr/lib/grub/grub-mkconfig_lib /usr/share/grub/grub-mkconfig_lib
Of course, figuring out what causes the reversion would be good too, but the symbolic link fix works so well that there's little point in exploring it further. Of course, if anyone can add how you'd do that, I'd welcome this advice too. New knowledge is always good.
A new repository for GNOME 3 Extensions
6th December 2011Not before time, the GNOME project has set up a central website for GNOME Shell extensions. It seems to be in the hands of extension developers to make GNOME 3 more palatable to those who find it not to their taste in its default configuration. If you are using Firefox, installation is as easy as clicking the ON/OFF icon for a particular plugin on its web page and then selecting install in the dialogue box that pops up. Of all the browsers that you can use on GNOME, it seems to be Firefox that is the only one that has this ability at the moment.
Though the website may have the alpha legend on there at present, it works well enough so far, so I have had no hesitation in using it for those extensions that are of interest to me. This is an interesting development that deserves to stay, especially when it detects that a plugin is incompatible with your version of GNOME.
Currently, I use GNOME 3.2, and it pops up a useful menu for deactivating extensions when the desktop fails to load. That's a welcome development because I have had extensions crashing GNOME 3.0 on me and running the GNOME Tweak Tool on the fallback desktop often was the only alternative. GNOME 3 seems to be growing up nicely.
All Change?
19th September 2011Could 2011 be remembered as the year when the desktop computing interface got a major overhaul? One part of this, Windows 8, won't be with us until next year, but there has been enough happening so far this year that has resulted in a lot of comment. With many if not all the changes, it is possible to detect the influence of interfaces used on smartphones. After all, the carry-over from Windows Phone 7 to the new Metro interface is unmistakeable.
Two developments in the Linux world have spawned a hell of an amount of comment: Canonical's decision to develop Unity for Ubuntu and the arrival of GNOME 3. While there have been many complaints about the changes made in both, there must be a fair few folk who are just getting on with using them without complaint. Maybe there are many who even quietly like the new interfaces. While I am not so sure about Unity, I surprised myself by taking to GNOME Shell so much that I installed it on Linux Mint. It remains a work in progress, as does Unity, but it'll be very interesting to see it mature. Perhaps a good number of the growing collection of GNOME Shell plugins could make it into the main codebase. If that were to happen, I could see it being welcomed by a good few folk.
There was little doubt that the changes in GNOME 3 looked daunting, so Ubuntu's taking a different approach is understandable until you come to realise how change that involves anyway. With GNOME 3 working so well for me, I feel disinclined to dally very much with Unity at all. In fact, I am writing these words on a Toshiba laptop running UGR, effectively Ubuntu running GNOME 3, and that could become my main home computing operating system in time.
For those who find these changes not to their taste, there are alternatives. Some Linux distributions are sticking with GNOME 2 as long as they can, and there apparently has been some mention of a fork to keep a GNOME 2 interface available indefinitely. However, there are other possibilities such as LXDE and XFCE out there too. In fact, until GNOME 3 won me over, LXDE was coming to mind as a place of safety until I learned that Linux Mint was retaining its desktop identity. As always, there's KDE too, but I have never warmed to that for some reason.
The latest version of OS X, Lion, also included some changes inspired by iOS, the operating system that powers both the iPhone and iPad. However, while the current edition of PC Pro highlights some disgruntlement in professional circles regarding Apple's direction, this does not seem to have aroused the kind of ire that has been abroad in the world of Linux. Is it because Linux users want to feel that they are in charge and that iMac and MacBook users are content to have decisions made for them so long as everything just works? Speaking for myself, the former description seems to fit me, though having choices means that I can reject decisions that I do not like so much.
At the time of writing, the release of a developer preview of the next version of Windows has been generating a lot of attention. It also appears that changes are headed for Windows users too. However, I get the sense that a more conservative interface option will be retained and that could be essential for avoiding the alienation of corporate users. After all, I cannot see the Metro interface gaining much favour in the working environment when so many of us have so much to do. Nevertheless, I plan to get my hands on the developer preview to have a look (the weekend proved too short for this). It will be very interesting to see how the next version of Windows develops, and I plan to keep an eye on it as it does so.
It now looks as if many will have their work cut out if they are to avoid where desktop computing interfaces are going. Established paradigms are being questioned, particularly as a result of touch interfaces on smartphones and tablets. Wii and Kinect have involved other ways of interacting with computers, too, so there's a lot of mileage in rethinking how we work with computers. So far, I have been able to deal with the changes in the world of Linux, but I am left wondering about the changes that Microsoft is making. After Vista, they need to be careful and they know that. Maybe, they'll be better at getting users through changes in computing interfaces than others, but it'll be very interesting to see what happens. Unlike open source community projects, they have the survival of a massive multinational at stake.
