[Kernel-packages] [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 Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1859071 Title: Native mode 2560x1080 is randomly unavailable on some boots Status in linux package in Ubuntu: New Bug description: $ lsb_release -rd Description: Ubuntu 19.10 Release: 19.10 $ apt-cache policy gdm3 gdm3: Installed: 3.34.1-1ubuntu1 Candidate: 3.34.1-1ubuntu1 Version table: *** 3.34.1-1ubuntu1 500 500 http://us.archive.ubuntu.com/ubuntu eoan/main amd64 Packages 100 /var/lib/dpkg/status $ apt-cache policy lightdm lightdm: Installed: 1.30.0-0ubuntu1 Candidate: 1.30.0-0ubuntu1 Version table: *** 1.30.0-0ubuntu1 500 500 http://us.archive.ubuntu.com/ubuntu eoan/universe amd64 Packages 100 /var/lib/dpkg/status $ lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09) I have a 3rd gen Intel laptop with only Ubuntu 19.10 installed, and a monitor attached via DisplayPort.

[Kernel-packages] [Bug 1859071] Re: Modesetting randomly fails to offer all modes available in the EDID
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 Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1859071 Title: Modesetting randomly fails to offer all modes available in the EDID Status in linux package in Ubuntu: Incomplete Status in xorg-server package in Ubuntu: Incomplete Bug description: $ lsb_release -rd Description: Ubuntu 19.10 Release: 19.10 $ apt-cache policy gdm3 gdm3: Installed: 3.34.1-1ubuntu1 Candidate: 3.34.1-1ubuntu1 Version table: *** 3.34.1-1ubuntu1 500 500 http://us.archive.ubuntu.com/ubuntu eoan/main amd64 Packages 100 /var/lib/dpkg/status $ apt-cache policy lightdm lightdm: Installed: 1.30.0-0ubuntu1 Candidate: 1.30.0-0ubuntu1 Version table: *** 1.30.0-0ubuntu1 500 500 http://us.archive.ubuntu.com/ubuntu eoan/universe amd64 Packages 100 /var/lib/dpkg/status $ lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09) I have a 3rd gen Intel laptop with only Ubuntu 19.10 installed, and a monitor attached via DisplayPort.
