The problem here is that the BUSID support for platform devices got broken after patch drm_device_keep_trying.patch was added to xorg-server (bug 982889).
As the BUSID is empty when initializing the omap x11 driver, it fails and move back to the old probing method, which allows more than one driver to be up at the same time (fixed previously by bug 1015292). ** This bug is no longer a duplicate of bug 982889 X trying to start before plymouth has finished using the drm driver ** Changed in: xf86-video-omap (Ubuntu) Status: New => Confirmed ** Package changed: xf86-video-omap (Ubuntu) => xorg-server (Ubuntu) ** Changed in: xorg-server (Ubuntu) Importance: Undecided => High ** Changed in: xorg-server (Ubuntu) Assignee: (unassigned) => Maarten Lankhorst (mlankhorst) -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xf86-video-omap in Ubuntu. https://bugs.launchpad.net/bugs/1161981 Title: Boot stalls after Ubuntu Raring desktop ARM (Panda board) install To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-ti-omap4/+bug/1161981/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
