Last modified: 2016-03-06 04:16:58 EST
Description of problem:
For current Fedora 23, X locks up frequently after switching back from a virtual console to X or after logging out from a GNOME session if a switch to a virtual console and back had been performed. This happens on a Lenovo ThinkPad T400 with a discrete AMD RV620 graphics engine using an external monitor attached to a docking station.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Log in and out a few times from GNOME and switch to a virtual console and back in between or switch to a virtual console and back.
Screen shows the virtual console superimposed by a frozen mouse pointer without any reaction to mouse or keyboard events.
Graphical login screen or graphical user session is restored.
