Not sure if it is a kernel issue or user-space. Truth is probably somewhere in the middle. It popped up moving to 3.8-rc1 using nouveau. Using nvidia's driver works fine. With nouveau, after entering login credentials in lightDM the user session does not start and I am back at the lightDM login screen. This is shown in the syslog: Jan 5 11:28:34 linux-e6410-1 rtkit-daemon[1888]: Successfully made thread 4920 of process 4920 (n/a) owned by '110' high priority at nice level -11.

Did not try xcompmgr. Gr. AvS _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
