I am running 64-bit Trusty Tahr.
Since I updated "gnome-screensaver" from 3.6.1-0ubuntu11 to
3.6.1-0ubuntu13 , the radeon (OSS) graphics driver fails, causing
Xorg/LightDM to restart, with the following message (dmesg) :
[ 3994.889128] [drm:radeon_cs_ioctl] *ERROR* Failed to parse relocation -2!

Obviously that may be radeon/Xorg/Compiz the culprit, not gnome-
screensaver which only triggers the bug.
Thanks for reading,
