The problem still occurs when using a kernel from vivid (3.19.0-35). If I login, the resolution is not correct. If I fix the resolution everything is fine until I logout (no need to reboot). If I login again, the resolution is bad again.
The available resolutions seem to change from time to time. Sometimes after login I get only 1920x1080 when doing a login, but it drops back to 1024x768 as well, sometimes rescaling to 1920x1080 if I wait a bit longer (the error messag already appeared at that time). After logging in and waiting approximately 20 seconds I can go to display options and reset my display to the full resolution( 3840x2160). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1515784 Title: UHD resolution not found when logging in, can select after login To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1515784/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
