Description Alexander Monakov 2013-04-15 21:35:47 UTC

Looks like since

[PATCH] xfree86: use udev to provide device enumeration for kms devices
http://lists.x.org/archives/xorg-devel/2012-June/031669.html

the server will attempt to initialize GPU devices other than specified by the -isolateDevice option.

At the moment, in combination with Ubuntu patches it leads to this failure:

https://launchpadlibrarian.net/135935376/Xorg.8.log

even though in addition to -isolateDevice, "AutoAddGPU" "False" is specified in the config, and then Section "Device" follows, specifying the driver (nvidia), but not the BusID.  Adding BusID eliminates the issue.
