--- Comment #9 from Fermulator freedesktop-bugs@fermulator.fastmail.org --- this morning, at the system physically
the issue I submitted originally is no longer happening (there have been several kernel updates since original submission ...)
$ uname -r 4.17.17-100.fc27.x86_64
now however, the symptom is:
noticed that the same monitor (connected via DisplayPort) had mis-match capabilities (wasn't able to go max resolution)
``` $ xrandr Screen 0: minimum 320 x 200, current 3840 x 1200, maximum 16384 x 16384 DisplayPort-0 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 1920x1080 59.95* 1600x1200 59.95 1680x1050 59.95 1280x1024 59.95 1440x900 59.95 1280x800 59.95 1280x720 59.95 1024x768 59.95 800x600 59.95 640x480 59.95 HDMI-A-0 disconnected (normal left inverted right x axis y axis) DVI-D-0 connected 1920x1200+1920+0 (normal left inverted right x axis y axis) 518mm x 324mm 1920x1200 59.95*+ 1920x1080 59.95 1600x1200 60.00 1680x1050 59.95 1280x1024 60.02 1440x900 59.95 1280x960 60.00 1280x800 59.95 1280x720 59.95 1024x768 60.00 800x600 60.32 56.25 640x480 59.94 ```
The " 1920x1200 59.95*+" option is missing from the display port monitor.
If I disconnect the DP, and reconnect, it comes back.
``` $ xrandr | grep + DisplayPort-0 connected primary 1920x1200+0+0 (normal left inverted right x axis y axis) 518mm x 324mm 1920x1200 59.95*+ DVI-D-0 connected 1920x1200+1920+0 (normal left inverted right x axis y axis) 518mm x 324mm 1920x1200 59.95*+ ```
