Usually there is not need for the whole sequence, just Alt-SysRq-R, which takes the keyboard away from X. You can then switch to a text console with Ctrl-Alt-F1. However: Sometimes (well, most of the times during my last ATI struggles) the screen was still blank. But I could reboot with Ctrl-Alt-Del. And sometimes the system was so frozen even the SysRq trick did not help. But in cases when only HAL does not work and recognize the keyboard, Alt-SysRQ-R should work just fine. > With the open drivers all works as it should with SysRq but I like > 3D-acceleration and that is by now far away for my chipset with open > drivers. I know how you feel, I also had huge problems with that. And then, all of a sudden, with the new 2.6.31-tuxonice kernel, everything was fine and working. Wonko
