Comment 67 for bug 16873

I experienced a similar situation where X and Gnome just freeze upon login(no blank screen; the screen just froze). I couldn"t access a console, mouse or anything for that matter. Only a hard re-boot (pressing the power button) would release the system.I have been experiencing this problem since i tried to upgrade (sudo apt-get dist-upgrade) to Ubuntu 6.06 Dapper beta2. I have dont have any such problem on my Ubuntu 5.10 installation. I have a ATI (ATI Radeon 9600)graphics card. (Toshiba SA60 laptop). I have had to downgrade back to Ubuntu 5.10. Could this be the same problem? Or would this be a different issue?
