I also confirm that problem continue to exists for Ubuntu 14.04 using th standard Linux X1 3.13.0-30-generic #54-Ubuntu SMP Mon Jun 9 22:45:01 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux kernel.
The way around it is to go the console, adjust the brightness to desired level, then go back to X. Brightness adjustment doesn't work at all when in X. Just console after I unplug the external monitor or reboot the entire machine. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1291371 Title: thinkpad screen dims after unplugging external display, and won't re- brighten without leaving X To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1291371/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
