Hi! So, there was a pretty bad regression with modesetting on nouveau
that got caught by one of my coworkers which could lead to screens
connected to docks not coming up at all on laptops like the ThinkPad
P50. Note there isn't a public bug open for this, but I'll be happy to
open one if you would like.
Note as well that both of these patches are already upstream:
"drm/nouveau: Only release VCPI slots on mode changes" is already in
master, and "drm/nouveau: Only recalculate PBN/VCPI on mode/connector
changes" is currently waiting to get pulled into the kernel from
drm-fixes. So you guys shouldn't need to carry these patches around
downstream for very long.
