[Bug 1859071] Re: Modesetting randomly fails to offer all modes available in the EDID
Great, thanks. Indeed the native mode of the monitor is missing from that list so this is a kernel or hardware problem. I assume the same command /usually/ shows more modes..? ** No longer affects: xorg-server (Ubuntu) ** Changed in: linux (Ubuntu) Status: Incomplete => New ** Summary changed: - Modesetting randomly fails to offer all modes available in the EDID + Native mode 2560x1080 is randomly unavailable on some boots -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1859071 Title: Native mode 2560x1080 is randomly unavailable on some boots To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1859071/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

It took me many reboots, but i finally got it for you! =) ** Attachment added: "modes.txt" https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1859071/+attachment/5321275/+files/modes.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1859071 Title: Modesetting randomly fails to offer all modes available in the EDID To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1859071/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Thanks! The login screen uses Wayland so that's also a good test in itself. If the issue affects the Wayland backend then it sounds like this is a kernel or hardware problem. To check that, next time the issue happens, please run: grep . /sys/class/drm/*/modes > modes.txt and then attach the file 'modes.txt' here. --- Just a guess: The problem might be timeouts on the i2c bus waiting for the monitor to return its EDID. So that could happen randomly. In that case, maybe try a different DisplayPort cable if you can. ** Also affects: linux (Ubuntu) Importance: Undecided Status: New ** Changed in: linux (Ubuntu) Status: New => Incomplete ** Changed in: linux (Ubuntu) Importance: Undecided => High -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1859071 Title: Modesetting randomly fails to offer all modes available in the EDID To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1859071/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hello Daniel, Today the issue occured again, so I was sure to login with "Ubuntu on Wayland", but the issue persisted until I rebooted (as usual). Please keep in mind the screen is in the wrong resolution while on the login screen, as well. Let me know if i can do anything else to help. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1859071 Title: Modesetting randomly fails to offer all modes available in the EDID To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1859071/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
