I've just had a freeze last night. My machine *reacted* on "ALT+SysRq+K".
After I pressed that combination a black screen with a wide blue stripe on the right side appeared including thin purple stripes and that screen stayed there. So I tried that key combo for 5 additional times. After the 5th time a window appeared saying something like: "Ubuntu is running in low graphics mode". I klicked "OK" and so another window appeared asking hot to proceed. I chose to stay in low graphics mode but right after I klicked that the screen turned and remained black. At least I was able to go to first real console (CTRL+ALT+F1). Graphics where screwed up but I was able to see that I was able to type although I couldn't see WHAT I was typing. So I blindly tried "/etc/init.d/gdm restart" which turned the screen into a light blue screen. After that I wasn't able to reach another real console again and I had to reboot anyway. -- Clocksource tsc unstable leads to lockups in Ubuntu Jaunty https://bugs.launchpad.net/bugs/355155 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
