https://bugs.freedesktop.org/show_bug.cgi?id=89664 --- Comment #15 from Omar --- I thought I'd give this another shot to see if things have changed since the last few kernel releases. Tested on: Linux Omar-PC 4.8.12-3-ARCH #1 SMP PREEMPT Thu Dec 8 16:10:23 CET 2016 x86_64 GNU/Linux Nouveau default behaviour: - Main GPU shortly blinks with boot information on the first screen followed by the second screen, then both power down. - The monitor attached to the second GPU shows the coloured stripes. - Turning the monitor on the second GPU off and back on again made it render a bright blue opaque screen. Nouveau with config=NvForcePost=1 behaviour: - All monitors power down, nothing is shown at all on either GPU. I'll attach the output of `journalctl -b --no-pager | grep nouveau` for both runs shortly. -- You are receiving this mail because: You are the assignee for the bug.
