Title:
With kernel 5.0.0-11-generic and nouveau, Ubuntu MATE has wrong colors
and can't control brightness
Status in Ubuntu MATE:
Invalid
Status in linux package in Ubuntu:
Fix Released
Bug description:
With the latest kernel (5.0.0-11-generic) my MacBook with nouveau
shows wrong colors and can't control brightness while running Ubuntu
MATE. For example, Ubuntu MATE green appears as teal and orange like
in the Firefox logo and window decorations is blue. This includes the
plymouth boot logo, but not the desktop wallpaper.
Screen brightness can't be controlled at all, neither with the
keyboard keys (which have always worked automatically) nor in the
Control Center > Power Management because no brightness slider appears
at all.
This also occurs in a live session from the latest daily build
(20190413.3).
It does NOT occur in a live session of the latest (20190413.2) Ubuntu
Desktop (GNOME).
By editing /etc/default/grub to boot the previous kernel (5.0.0-8-generic),
it works normally again.
