Public bug reported:
Binary package hint: xserver-xorg-video-ati
There are several bugs reported that seem similar to the issues that I
have, but they all appear somewhat different.
I use an X300, with dual head (merged fb mode) and AIGLX. Everything
works fine under KWin (including glxgears) and glxinfo reports direct
rendering.
However, when using beryl, the X server freezes after some random
interval (always within 2-3 minutes). The mouse is usually still
movable, but the keyboard is unresponsive, and X will not terminate when
told to when I ssh in from another machine. ps reports that X is
consuming 100% CPU. The only way to recover is to reboot from the
external machine.
Occasionally the X server appears to crash and restart, after which the
keyboard is again responsive, but X is still consuming the entire CPU
and the system is extremely sluggish until I reboot.
After trying many different options, I eventually found that by changing
colour depth down to 16 bits resolves the problem. After making this
change I have no further issues.
Regards,
Joe.
