I can set the resolution during the session, but on next login it returns back to full hd. This is a regression from vivid, where the resolution worked without problem. This happens with different window managers. In cinnamon I get an additional error, which is solved by removing .config/monitors.xml none of the selected modes were compatible with the possible modes: Trying modes for CRTC 63 CRTC 63: trying mode 1920x1080@60Hz with output at 3840x2160@60Hz (pass 0) CRTC 63: trying mode 1920x1080@60Hz with output at 3840x2160@60Hz (pass 1) Trying modes for CRTC 64 CRTC 64: trying mode 1920x1080@60Hz with output at 3840x2160@60Hz (pass 0) CRTC 64: trying mode 1920x1080@60Hz with output at 3840x2160@60Hz (pass 1) Trying modes for CRTC 65 CRTC 65: trying mode 1920x1080@60Hz with output at 3840x2160@60Hz (pass 0) CRTC 65: trying mode 1920x1080@60Hz with output at 3840x2160@60Hz (pass 1) Trying modes for CRTC 66 CRTC 66: trying mode 1920x1080@60Hz with output at 3840x2160@60Hz (pass 0) CRTC 66: trying mode 1920x1080@60Hz with output at 3840x2160@60Hz (pass 1) I'm willing to invest some time in trying to find a solution.
