Comment 18 for bug 327844

having the same problem on an Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller, getting the same lockup conditions where everything is frozen except for the mouse which can't click on anything......I have also noticed that once I have enabled emerald that sometimes it will look like it is locking up, but will let me click on the minimize maximize and close buttons on the corner of a window which will enable me to control it again (this isn't a fix since I have experienced one incident when this did not work, but I thought it might prove useful to others.......This is NOT the entire os locking up as I have the openssh-server running and can ssh in, and everything appears to be running normally, other than the fact that the xserver isn't responding. I agree that this bug is extremely serious to be happening at this stage (beta) of the development compared to my experience with the past three betas, I have never experienced a bug that completely rendered my installation useless
