X crashes in the current Ubuntu Jaunty Alpha releases after Gdm login. It works at first if I have removed compiz but afterwards it crashes again with the follow backtrace. It seems to work fine with vesa driver.

This time X started without Compiz fine again. After starting the 3D desktop with "compiz --replace" I got this backtrace: Program received signal SIGSEGV, Segmentation fault.

I also got the Xorg.0.log message before Compiz "exaCopyDirty: Pending damage region empty!" and afterwards the usual dmesg output "[ 44.072877] Xorg[3470]: segfault at bf417fc0 ip 080f64e6 sp bf417f90 error 6 in Xorg[8048000+199000]".
