VMware Workstation in full screen mode hobbles my keyboard
14th May 2008
Recently, I have encountered an odd situation following my recent upgrade to Ubuntu 8.04: when I use VMware Workstation to run Windows XP in full screen mode, the keyboard no longer acts as it should. For instance, the Caps Lock and Num Lock keys stop working, as does the Shift key. Logging out and back in again is the least that's needed to set things right, but there has to be a better way to resolve the problem. While I am not saying that it's limited to the scenario where I saw it happen, it's still very odd behaviour. If you have a solution, please let me know. Of course, I'll keep you posted if I find one. Meanwhile, I'll be avoiding full screen mode with VMware as much as I can.
Update 1:
I have done a spot of digging on this one since and gained the impression that there might be a conflict between VMware and the version of X.org Server that comes with Ubuntu. A restorative trick that I have seen suggested is to issue the following command in a terminal, replacing "gb" with your own locale, but I have yet to see if it works:
setxkbmap -rules xorg -layout "gb"
In any case, it looks as if it is not a permanent fix but just a way to keep working without resorting to system restarts, logging off and back on, etc.
Update 2:
I can now verify that the command quoted above works for me. Of course, it would better to find a permanent fix and even better for the behaviour never to occur at all. For now, though, any fix is better than none whatsoever.
Finding out what kernel version is running
5th May 2008
Here's the command that does the deed for me on Ubuntu:
uname -a
Usually, I only need it to find out what header files I need for any VMware repeat installations or reconfigurations.
Getting VMware Workstation working on Ubuntu 8.04
28th April 2008
With every change of kernel, a re-installation of VMware becomes necessary, and my move to Ubuntu "Hardy Heron" 8.04 was punctuated by the same activity. However, the advent of the 2.6.24.x kernel meant that my usual means were no longer successful, so a new approach was needed.
That involved the mysteriously named vmware-any-any patch, and version 116 of this seemed to set things to rights for me. Stopping the installation before vmware-config.pl runs is the best course of action, since it will only fail anyway. Downloading vmware-any-any-update-116.tgz, extracting from the archive and running runme.pl using sudo continues the process.
While it seemed to have worked for me, I must wonder at why VMware seems unbothered by the idea of keeping up with Linux kernels and C compilers. It would certainly have removed the need for the user community needing to do anything about the problems that others and I keep seeing; it's a very unusual arrangement.
Keyboard shortcuts for changing desktops in Ubuntu
4th April 2008
I am more than a little surprised that I didn't encounter these earlier: Ctrl + Alt + Left Arrow Key moves left, and Ctrl + Alt + Right Arrow Key moves right through your Ubuntu desktops or workspaces. It's always handy to be able to save on mouse work while doing this sort, so these could prove useful. I wouldn't be at all surprised if they applied to other Linux distros too.
Downloading Ubuntu
14th March 2008
When I was wandering around looking for a preview of Ubuntu Hardy Heron (8.04), it took a bit of blundering before I landed on cdimage.ubuntu.com. Since there are ample ISO images and torrents available for anyone's needs, I decided to keep the link somewhere handy for those who might need it.
Trying out Firefox 3 Beta 3 on Ubuntu
20th February 2008
Keeping an eye on future browser releases helps to avoid any shocks when maintaining publicly available websites. Therefore, it should come as no surprise that I have been giving Firefox 3 a whirl. As it happens, I have had it going on both Windows and Ubuntu. With the former, I have not encountered any obvious problems, but I am wondering if the new bookmarking system will mean anything to me. For installation on Ubuntu, I used the following command (I think that I culled it from Tombuntu but can't remember offhand...):
wget -P ~ ftp://ftp.mozilla.org/pub/firefox/releases/3.0b3/linux-i686/en-US/firefox-3.0b3.tar.bz2 && tar xjf ~/firefox-3.0b3.tar.bz2 -C ~
The nice thing about the above is that it places the test installation in your home directory and away from Firefox 2. It also works regardless of what Linux distribution you have. The profiles get shared between versions, so a backup would be a good idea before you start to tinker. As with the Windows version, page loading and rendering is faster in the new version, but I found a problem with printing that, I hope, will get sorted before the final release. Another area for attention is font rendering: it could be sharper for sans serif fonts on Ubuntu and serif fonts on Windows. Otherwise, it works well on both platforms and I like the way that open windows are saved on exit, an excellent idea carried over from Opera.
Fixing VMware CPU speed misreporting on Ubuntu
4th February 2008
Over the last week, I have had VMware misreport the speed of my CPU and have virtual machines like they're on speed. To cure it, I tried restarting the PC a few times but that yielded no joy, even if it did work the last time that VMware did this on me. Following some instructions from the Ubuntu forums set things back onto an even keel again. The commands required follow:
sudo apt-get install linux-headers-$(uname -r) build-essential gcc-3.4
tar xzf VMware-workstation-6.0.2-59824.x86_64.tar.gz
export CC=/usr/bin/gcc-3.4 && cd vmware-distrib && sudo ./vmware-install.pl
The first of these adds in a specific version of the GNU C compiler while also adding kernel headers; the latter weren't needed on my system since I already had them. The second extracts the files from the tarball, while the last performs the required installation rites.
Running Photoshop Elements 5 using WINE on Ubuntu and openSUSE
23rd January 2008
When you buy a piece of software and get accustomed to its ways of working, it is natural to want to continue using it. That applied to a number of applications when I moved over to Linux in the latter half of last year, and one of these was Adobe's Photoshop Elements 5.0, a purchase made earlier in the year. My way forward was to hang on to Windows by way of VMware. However, Elements fails to edit or save files in the Linux file system accessed through VMware's shared folders feature. I have yet to work out what's happening, but the idea of using a more conventional networking arrangement has come to mind.
Another idea that intrigued me was the idea of using WINE, the Windows API emulator for Linux. You can get it in the Ubuntu and openSUSE software repositories, but the WINE website has more to say on the subject. That's only the first stage, though, as you might see from WINE's Wiki page on Photoshop and its like. However, their advice is a spot incomplete, so I'll make it more explicit here. You need to run Winetricks from its online home as follows:
wget kegel.com/wine/winetricks; sh winetricks fakeie6
wget kegel.com/wine/winetricks; sh winetricks mdac28
wget kegel.com/wine/winetricks; sh winetricks jet40
The first line flicks a switch to fool Microsoft components to install thinking that they are installing into a Windows system with IE on board. Without this, the rest will not happen. The second installs Microsoft's native ODBC drivers; Elements will not function at all without these if my experience is any guide. The last step is to add JET support so that Elements' Organiser can get going. With all of these in place, having a working Photoshop Elements instance under Linux should be a goer. Apart from the odd crash, things seem to be working OK on Ubuntu and openSUSE seems hospitable too. Further experimentation may reveal more.
Update: The WINE Wiki has now been updated (and links back here!). As per dank's comment, the above lines can be condensed into what you see below:
wget kegel.com/wine/winetricks; sh winetricks fakeie6 mdac28 jet40
Succumbing to Temptation: Ubuntu Studio
12th December 2007
Because the fancy artwork that comes with Ubuntu Studio does look appealing, I got lured into converting my vanilla Ubuntu 7.10 into something a bit more avant-garde. The theme's all very dark (you can have a peek here; file size is 1.1 MB) but it has a very appealing look, even if the merging of the application title bar and top desktop panel due to their having the same colour and texture is a little disconcerting. My momentary lapse of discipline also got me adding a whole array of audio, graphics and movie applications that I may never use; it's good to have them if I ever fancy a fiddle, but removal is not off the agenda either. The other thing that came with the package was an alternate kernel that looks as if it might be of the real time variety, at least if the "rt" in its package name is to be believed. The main reason for mentioning that is that VMware has ceased working, so I need to snag the correct kernel source code to get things going again. Let's hope that it's a successful venture...
Update: After a spot of poking, Synaptic offered up the required kernel header files and VMware was reinstated with only a modicum of effort. All's well that ends well.
Setting up automatic Firefox updates on Ubuntu with Ubuntuzilla
1st December 2007
No sooner had we received Firefox 2.0.0.10 than they have already started talking about 2.0.0.11. Apparently, the latest update broke support for a tag that I have never used: canvas. This is stuff that makes you wonder about their quality control.
Because the 2.0.0.10 was a security update, Ubuntu volunteered it to me without any effort on my part. However, I am using Ubuntuzilla, so I didn't get the update coming through to my browsing world without further intervention. Launching Firefox using the gksu command allowed me to update the thing like I have been doing on Windows: Help > Check for Updates... Now, I have got a more permanent check set up, thanks to my issuing the following command:
ubuntuzilla.py -a installupdater -p firefox
