Title:
Fix shrinking behavior in rrCheckPixmapBounding
Status in HWE Next:

Status in xorg-server package in Ubuntu:

Status in xorg-server source package in Xenial:
Won't Fix
Bug description:
[Impact]
When using extended mode on an slave-output connected external monitor,
RRSetCrtc calls rrCheckPixmapBounding, which shrinks the output area. It makes
the slave-output configured to scan-out an area which completely falls outside
of the screen-pixmap, and end up with
a black display on the external monitor.
We need these two commits:
a46afee84d45fbff4e4dad9376afc95bbcc31d7c randr: rrCheckPixmapBounding: do not
shrink the screen_pixmap
3b624aa9a9df86dc7d48149e0f18ca223b4355f1 randr: rrCheckPixmapBounding: Do not
substract crtc non 0 x,y from screen size
[Test Case]
Enable NVIDIA PRIME, plug an external monitor, and change to extended mode.
[Regression Potential]
There should be none, the shrinking behavior wasn't right at the first place.
