Setting SAVE_VIDEO_PCI_STATE=true in /etc/default/acpi-support did note solve the problem - it happened again today. Once the screen goes buggy after resume, I can't do anything to turn the light back on.
I tried all pm-suspend quirks. Hibernating brings the screen back on during boot-up, but as soon as I get to the resumed desktop it's off again. Switching to console (Ctrl+Alt+F1) and back doesn't bring the light on at any moment. The only way to get the light back on is with a full reboot. Must be a bug with the Intel driver then...? Maybe I should turn off kernel-mode setting and try the console-switch method next time it happens? If anyone knows anything I can try, please let me know. -- [gm45] Backlight sometimes stays off after resume on Lenovo X200 https://bugs.launchpad.net/bugs/580225 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
