Created attachment 118807 [details] dmesg.display_port_problem.4.2.3-300.fc23.x86_64 I get a flood of kernel events from nouveau when connecting and disconnecting my 2nd display via the display port cable. Events start with this: nouveau E[ PDISP][0000:01:00.0] INVALID_VALUE [UNK84] chid 0 mthd 0x0700 data 0x00052002 modinfo nouveau -n /lib/modules/4.2.3-300.fc23.x86_64/kernel/drivers/gpu/drm/nouveau/nouveau.ko.xz lspci -v | grep -i vga 01:00.0 VGA compatible controller: NVIDIA Corporation G92GLM [Quadro FX 2800M] (rev a2) (prog-if 00 [VGA controller]) Errors come and go with connection/disconnection of the Display Port cable. So long as I stay running in init 3, the primary laptop LCD continues to function. Once I go init 5, X appears to start, and then just hangs. I've attached dmesg output for boot-up, when I connect the display port, and when I disconnect the display port. Please let me know if I can help in any way.

I should also add - I do not have this problem when running CentOS 7 - 3.10

Please attach your VBIOS as well (you can retrieve it from /sys/kernel/debug/dri/0/vbios.rom )
