I just spent the better part of a day getting Beryl to run on my P IV 2.4gh, ATI radeon 9600SE. I followed the instructions on wiki.beryl-project.org for the install.
My fxglrinfo is normal. Card/manufactured is identified, everything's great.
my /etc/X11/xorg.config has the extra bit at the bottom disabling composites (as fxglrinfo got angry without this).
My shell scripts are identical to those on the wiki. I initially added beryl-manager in my startup but am now running it from the terminal after my XGL session starts as it likes to crash (to a black screen with a pointer) sporadically during boot.
Running beryl-manager from the terminal doesn't bother me. The problem comes when I get the same type of crash (black screen, pointer, blue/white line occasionally in the corner of the screen) when I maximize firefox or swiftfox. Small windows work fine. Maximize button leads to crash (about 80% of the time).
I can't think of what to do with this where it is only occuring sometimes. It seems less frequent when I run beryl-manager in the foreground (without &) from my terminal window and leave that window open. Not sure why that would make a difference but it seems to.
Any ideas on what to do with this?
