Ah, sso I think this bug and bug 619397 are actually duplicates. When you remove the power cable, then gnome-power-manager tries to adjust the screen brightness.
So this looks like a bug in the ATI kernel DRM driver. Do you get the freeze if you do this? echo 3 | sudo tee /sys/class/backlight/*/brightness Please also give me the output of ls -l /sys/class/backlight/ for completeness. -- Computer freeze when removing power cable https://bugs.launchpad.net/bugs/615803 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
