I have upgraded the Catalyst driver to the version 14.12 installing directly the deb packages taken from the official amd website.
I have applied the workaround suggested here: http://askubuntu.com/questions/540780/14-10-wine-and-fglrx-conflict to solve the conflict fglrx/wine on Ubuntu 14.04 and everything works fine. I can logout with both graphic cards without any issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1310071 Title: Low graphics mode on logout To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fglrx-installer-updates/+bug/1310071/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
