Now I tried all the Trusty HWEs and it seems to have started with Wily. xserver-xorg-video-radeon-lts-wily 1:7.5.0+git20150819-0ubuntu1~trusty1 linux-image-generic-lts-wily 4.2.0.42.34 xserver-xorg-core-lts-wily 2:1.17.2-1ubuntu9.1~trusty1 mesa-lts-wily 11.0.2-1ubuntu4~trusty1
I had once wrong colors with the Trusty initial stack (3.13), which I couldn't reproduce. And I was just told that disabling DPMS / monitor power management in KDE also prevents the problem, which might correlate with the fact, that running a DPMS "force off" / "force on" cycle also restores the colors correctly. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1643843 Title: Distorted colours after suspend / resume cycle To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1643843/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
