Thanks for testing and the update. That is good news that the bug is fixed in 3.14-rc1. Can you also test the latest 3.13 stable kernel, which is 3.13.1? It can be downloaded from:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.13.1-trusty/ That is the kernel currently in -proposed. So if the bug is fixed there, it will land in Trusty shortly. If the bug is not fixed in 3.13.1, we can perform a reverse bisect to identify the fix in 3.14-rc1. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1276037 Title: [Thinkpad T420s] Brightness dims when unplugging external monitor and cannot be changed afterwards To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1276037/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
