I updated to ati-drivers-12.2 to finally fix the xv issue (bug 391193). I opened amdcccle (as root), selected "Display Manager", and changed my desktop from cloned to multi-display (I have 2 monitors). When I hit "apply", amdcccle closed, and I saw the following in the console. (process:12156): GLib-GObject-CRITICAL **: gtype.c:2715: You forgot to call g_type_init() (process:12156): GLib-CRITICAL **: g_once_init_leave: assertion `initialization_value != 0' failed (process:12156): GLib-GObject-CRITICAL **: gtype.c:2715: You forgot to call g_type_init() (process:12156): GLib-CRITICAL **: g_once_init_leave: assertion `initialization_value != 0' failed (process:12156): GLib-GObject-CRITICAL **: g_object_new: assertion `G_TYPE_IS_OBJECT (object_type)' failed Segmentation Fault After updating the drivers, I ran "/opt/bin/aticonfig --initial -f". Luckily, that backed up my old xorg.conf, so I used it to set back my dual monitor setup.
That piece of software is proprietary, we can't fix it. Get a stack trace and report to the unofficial fglrx bugzilla http://ati.cchtml.com/
if you open a bug in the unofficial fglrx bugzilla add the link here please, thank you
Someone else posted it already, I'll just add to that. http://ati.cchtml.com/show_bug.cgi?id=346
Closing this bug, as 12.2 is not available in tree anymore. Please reopen, if you can reproduce with a recent version.
