Johannes, The problem in comment #6 sounds like a hotplug event, like the whole HDMI connection was lost and then reconnected. Next time the problem happens please immediately run: journalctl -b0 > journal.txt and attach the resulting text file here. ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1926032 Title: [i915] Screen "disconnects" when updating screen buffer To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1926032/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1926032] Re: [i915] Screen "disconnects" when updating screen buffer
This problem is persisting and today I noticed something I think might help pinpoint the problem. I was playing a slide show in shotwell when the screen went black again and when it came back on after a few seconds, the last picture displayed was stuck and the new pictures were displaying in a corner in a much smaller frame as if the system just tried to reset the resolution to something much smaller and then changed its mind and reverted (but shotwell didn't get the message and kept rendering to the small resolution rather than the wide one). Hope this helps to pinpoint the issue. ** Attachment added: "IMG_2026_111933.jpg" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1926032/+attachment/5541181/+files/IMG_2026_111933.jpg -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1926032 Title: [i915] Screen "disconnects" when updating screen buffer To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1926032/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1926032] Re: [i915] Screen "disconnects" when updating screen buffer
There certainly are invisible differences between Linux and Windows kernels internally how they implement HDMI signalling. So it is possible Linux is more fragile than Windows in this respect. As such, avoiding the receiver or changing cables might be a workaround. A proper fix in that case would go in the kernel so reassigning there... ** No longer affects: xorg-server (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1926032 Title: [i915] Screen "disconnects" when updating screen buffer To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1926032/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1926032] Re: [i915] Screen "disconnects" when updating screen buffer
Most certainly not a problem with hdmi connection. I have had windows installed on the same machine without issues. The behavior is such that it is very clear that as soon as you move the mouse after a period of idle, the problem occurs. Also if the computer receives a notification after a period of idle it occurs. There is a definite link to activity which renders new information on the screen buffer. It can play a movie without a problem on vlc but when I pause, it disconnects the screen (presumably because the "pause" bars appear on the screen). If I right click to add subtitles or change something else in the video it also appears at the exact same time I click. This problem is very repeatable. I can do a phone quality video if that would be of interest. If it was a problem with hdmi it would be more random in behavior and it would be a problem on windows as well. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1926032 Title: [i915] Screen "disconnects" when updating screen buffer To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1926032/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
