Something similar, happens on my Dell XPS M1210 with Dual Boot Windows XP and Ubuntu 8.10. My system suddenlly freezes even the clock stops, but I can move my cursor in very very slow and not-smooth way. Keyboard does not respond. Ctrl+Alt+del or backspace doesn't work. But during all this process my 'thinking' LED (I dont know how to call it) is on. Its like if suddenlly an applications starts using 100% of CPU capability and everything slows down and freezez. Just like in windows 95...
This has happened to me about 5 times this week. And everytime I have been using different applications so I dont know if there is anything in common (besides the symptoms). I am no sure but I think that in this 5 times, I had a pdf viewer running (could have been evince or acroread, I use both). By the way in each of this five times I had to force reebot by using the power button. I will try to run top a dmesg if this happend again, but really don't think that ctrl+alt+f2 will work. Any other thing I could attach to give you more information? -- Xubuntu 8.10 intrepid ibex - Sony Vaio PCG-V505BX freezes within 30 minutes or so https://bugs.launchpad.net/bugs/300966 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
