Per a suggestion on the xubuntu-devel IRC channel, I tested the intel xorg-edgers ppa driver -- to no avail.
Next suggestion was to try a later kernel. First, I did a fresh install of the current vivid daily image and confirmed that problem was still present. Then I installed the latest 3.17 kernel and that did seem to resolve the problem. So for the heck of it, I then installed the latest 3.19 RC and it's working okay with that one too. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1384515 Title: Laptop screen dims on logout To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1384515/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
