Christopher, I believe Wayland is a default display server on Ubuntu nowadays (at least in 17.10). As it is some hassle for me to set up the test environment and mess around with all the cables again, I would like to understand, why the logs I have enclosed are not good enough. ** Changed in: xserver-xorg-video-ati (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to 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 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1509997] Re: 1002:6821 Graphical issues when radeon MST enabled
Christopher: 1) I used to have radeon.dpm=1 to save power (although, I don't have numbers how much better it is with respect to no parameter). 2) I can't. My Ubuntu 17.10 (and according to my knowledge it's a trend in the community) runs with Wayland, not Xorg so there is not Xorg server with its log file. Thus, as suggested on the webpage (https://fedoraproject.org/wiki/How_to_debug_Wayland_problems), I use journalctl to combine all relevant log information. Thus, you do have entire logs, only with different file names. ** Changed in: xserver-xorg-video-ati (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to 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 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1509997] Re: 1002:6821 Graphical issues when radeon MST enabled
I have tried today’s version of the next Ubuntu (16.04) -> the problem hasn't been resolved. The system behaves as my current instillation (15.10) before log-in: ".. two Dell screens, laptop's screens got off. The Dell screens are properly detected as separate: I can move mouse from one screen to another. Image on the last Dell screen is defected (blur) as in the attached picture." ** Changed in: xserver-xorg-video-ati (Ubuntu) Status: Incomplete => New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to 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 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Adrian, to clarify, does using fglrx provide a WORKAROUND via https://help.ubuntu.com/community/BinaryDriverHowto/AMD ? ** Changed in: xserver-xorg-video-ati (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to 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 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1509997] Re: 1002:6821 Graphical issues when radeon MST enabled
Yes, in property drivers (fglrx) the MST feature is implemented correctly and thus can be considered as a workaround. ** Changed in: xserver-xorg-video-ati (Ubuntu) Status: Incomplete => New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to 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 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
