Here's one choice little problem that remained after a failed partial upgrade to Ubuntu 9.04 beta.
After boot, the message "Starting up... Undefined video mode 31f" comes up, with a list of all supported video modes below it. You can press enter and choose the video mode which you would like. In my case, that's 37D.
Here's how to fix it:
Open /boot/grub/menu.lst in your favourite editor (gedit, nano) as su, i.e. sudo gedit...
Search for "vga=". In my case, it was vga=799. I replaced "799" with "893", rebooted and all was well.
In your case, you need to check what the hex number is for the mode you want. Google for a hex to decimal converter and convert that hex code to decimal. 31f = 799, 37d = 893, etc. Change the value at the first "vga=" instance to the value that matches the video mode you want, reboot and all should be well.
Cheers!!

Ubuntu 9.04 Jaunty Jackalope Upgrade
I did it. You probably did too. Bit the bullet and upgraded to Ubuntu 9.04 Jaunty Jackalope.
I've only upgraded my workstation but still have my HTPC and WWW server to go. I'm nervous about those two.
The upgrade is pretty straight forward. Just press "Upgrade" in the software update dialog that raises its head every so often and let the software do its thing. Chances are, if your machine was running in a stable manner before the upgrade, it will be afterwards.
There were two things which bothered me about the upgrade:
1. It removed Google Picasa Beta 3. No big trouble to reinstall it, but as I have more than 100K images on an NFS share the reindex is going to take a long time. The nasty thing about it is that it removed as part of the "Remove Obsolete Packages" component of the upgrade. Watch out for this.
2. The only other headache so far, and this update is only a few hours old now, is that the Tracker Applet keeps reporting "There was an error while performing indexing: Index corrupted". Again, not too bad, as there are a couple of possible fixes for it reported here: https://bugs.launchpad.net/ubuntu/+source/tracker/+bug/361560.
The fix I chose was to kill the related processes and delete the indexes, etc and reboot. No problems with the system after that.
The better fix is in the post by Bryan McLellan. Here's how he did it:
"...
Found a workaround/fix that's more user friendly:
sudo apt-get install tracker-utils
tracker-processes -r # --hard-reset
Then I logged out and back in so the processes that I had previously killed by hand would restart in a normal fashion.
..."
I came across one more solution that is an extension of the one above. It's a little more elegant and complete in some ways. YMMV, etc. Try this:
I'll be back with more posts on what went right, what went wrong and some other info about this upgrade soon.
Cheers!!

First post...
Hi there...
Despite my name being TechnoMage, I'm more TechnoHippie these days. Certainly no Techno Viking. I'm too much of a lard arse for that.
What's this blog about? Technology. Not bleeding edge, nothing wild. Mostly Linux. Mostly hacks. Mostly ways to get things to work and share the fixes I've found for things that don't work the way you expect or stuff that's broken and more importantly, how to fix it.
I'm tooling around with Ubuntu. I dumped Windows quite some time ago because the license fees for Vista were beyond my means. I found lots of bugs and things that I was generally unhappy with in Vista RCx as well.
There are lots of places on the web to find solutions to Ubuntu and tech issues. Many, many places. A bewildering array of sites. Some are correct, some are half correct and some are just downright wrong. My idea is to try to being these tips, tricks and techniques for the most common problems into one place to make it easy to go from zero to hero quickly and with a minimum of pain.
So far, I run all my businesses solely on Ubuntu. That's not to say that Ubuntu is not without bugs and hassles. It's not an operating system which is perfect. None of them are. However, it's pretty good for general use. As soon as you want to do something different you will need to get your hands dirty in the command line environment. I'll show you what I do as it happens to make Ubuntu a better place to be for most purposes.
Back soon with some meaningful posts.
