I have recently bought myself a new graphics card (Geforce FX5500 w/ 256MB RAM) and have been playing around with XGL.
When I'm using XGL my system crashes at almost regular intervals.
After doing some research I have found that it could be down to three things:
1) The firefox Flash extension is known to affect XGL. (or the other way around) The solutions posed to resolve this have been to either install or removeone or the other of these (Ubuntu package names): libflash and mozilla-flashplugin.
Another solution has been to install libXext-devel. I thought I should
try this one as I want to avoid disabling Flash.
The problem is that there is a missing dependency, mesa-libGL. When
reading through the mailing list I found that these have recently been
updated but the rpm doesn't appear to be in the repository yet.
2) My keyboard settings: When I login with XGL I get an information dialog that asks me whether to use the X keyboard settings or the GNOME keyboard settings. Choosing either doesn't seem to affect how long it takes for the system to crash.
How would I go about making the settings the same?
3) XGL itself. As XGL is still considered beta software by many people, maybe I should disable and just wait a while.
