** Attachment added: "WifiSyslog.txt"
https://bugs.launchpad.net/bugs/1824815/+attachment/5256158/+files/WifiSyslog.txt
** Description changed:
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.
