Adrian: 1) To clarify, do you need to use radeon.dpm=1 for a reason or are you just testing it to see if it does anything different?
2) While using the latest mainline kernel, please attach dmesg and xorg in their entierty only for the scenario of when using radeon.mst=1, and please don't rename the log file names. ** Changed in: xserver-xorg-video-ati (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/1509997 Title: 1002:6821 Graphical issues when radeon MST enabled To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-driver-ati/+bug/1509997/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
