Priority: medium Bug ID: 81563 Assignee: dri-devel@lists.freedesktop.org Summary: Black screen and only mouse pointer visible with GNOME Shell Severity: normal Classification: Unclassified OS: All Reporter: paulepanter@users.sourceforge.net Hardware: Other Status: NEW Version: XOrg CVS Component: DRM/Radeon Product: DRI
With Debian Sid/unstable and `xserver-xorg-video-radeon` 7.4.0-2 and `gnome-shell` 3.12.2-3, the screensaver was on and the monitor in power saving mode. Entering the password there was just a black screen and the mouse pointer, which could be moved. (No idea if the password input dialog was ever shown.)
This is not reproducible, so no idea how to debug this. I attached to the process `gnome-shell` and got the following backtrace. No idea if the process `gnome-shell` is responsible for this though.
