Talk:Ubuntu Gutsy Installation Guide
Updated some information only applicable for Gutsy
I've updated some minor details about the fglrx-installation in Gutsy:
- By default, Gutsy (and Feisty too) now have Universe and Multiverse enabled
- The fglrx-version in Gutsy's linux-restricted-modules is 8.37.6 and not 8.28.8

- fglrxinfo gives: libGL.so.1: cannot open shared object file.
- Fixed with command:
sudo ln /usr/lib/libGL.so.1.2 /usr/lib/libGL.so.1
I followed this guide and fglrxinfo yielded the desired output.
But then I still got the following problems:
- crash/restart of X when trying to run glxgears
- crash/restart of X when trying to watch mythtv recording
- visual artefacts from window creation
The cause I assumed in that:
glxinfo | grep direct
did not yield 'yes' but 'no' and 'Mesa Indirect'
Long search, quick solution:
sudo apt-get remove xserver-xgl
Note: I don't really know what this actually does in the context of a desired installation, so try at your own risk. I assume this being installed from my earlier Feisty installation where I tried out compiz and AIGLX was not supported by the driver.
After removing the xserver-xgl package, all problems described above vanished.
Maybe someone with more detailed knowledge might find it useful to add a paragraph to the page.
Comment: I had a lot of trouble until I found your solution. Removing xserver-xgl made most of the graphical artifacts disappear (I still have some black bars in the bottom right corner of one screen), and made my dual screen setup work again. Should this be in the general guide?
