Please check if there is a way to disable DGA support on VMWARE and try it to see if that problem is really DGA related. If not on VMWARE, it's possible to turn off DGA extension support on XF86Config-4 (I don't know it by heart by I can find that out for you). > * glxgears performance is limited to approx. 500 fps ; this seems rather > below par to me, wrt. to benchmarks of equivalent Radeon desktop models > (700-1000 fps). What bitdepth are you using?

The first strange thing is that there is a difference between the nightly binary packages and your own compiled CVS snapshot. What version of gcc/libc do you have? Try to get a backtrace from the segmentation by making export LIBGL_DEBUG=verbose gdb glxinfo run (segmentation fault) bt quit and paste it here. Regarding the 2nd case, have you followed the right steps to install the compiled CVS tree? That is, have installed [sperately] X and the kernel drivers?
