http://bugzilla.opensuse.org/show_bug.cgi?id=1124603 Bug ID: 1124603 Summary: Various DisplayPort multi-monitor enabling and positioning randomness Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.0 Hardware: x86-64 OS: All Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-maintainers@forge.provo.novell.com Reporter: novell@regproctor.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- These symptoms may have the same source as the bug 1109968. This is on Leap 15 with 6 DisplayPort monitors on an AMD Eyefinity 6 display card that runs on the native Linux Radeon driver and I use KDE. If you knock a DP cable so that a monitor is temporarily disconnected, even for a fraction of a second, several things can happen. With a little luck everything will come back as it was but more likely these thing will happen, perhaps just a few and perhaps all: - The monitor may stay off even going through a disable/enable cycle in the KDE multi-monitor settings. However, sometimes it will come back on. - If you can get a monitor to come on through a disable/enable cycle it may not be in the same place. When you move it and save it to it's correct place it may still behave as if it is in another position. When you finally restart the computer because you can't seem to correct it while in KDE (perhaps logging out and back in would do the same thing) you see it positioned offset from where it was (in one case a whole monitor height upwards) but at least this time you can put it back in the correct place. It would be awesome if eventually Linux could handle DisplayPort monitors being connected and disconnected while running as I have not yet ever seen it get things correct consistently. That said, it seems to be slowly getting better. An example of something that could be much better is that if the a monitor gets disconnected and Linux moves all your items on the display off it, to have those items put back when you reconnect the display would be of great value. If this is all hard to visualize I could perhaps force this to happen and make a video showing the strangeness. -- You are receiving this mail because: You are on the CC list for the bug.
