Title:
Display orientation resets on reboot with USB-C external monitor and
refresh rate dropdown disappears when setting it sometimes
Status in gnome-shell package in Ubuntu:
Incomplete
Bug description:
When rebooting with USB-C external monitor (3440x1440) attached,
display orientation in "gnome-control-center display" resets requiring
one to reposition the windows on boot. Very annoying.
In addition, refresh rate drop down for external display sometimes
goes missing when setting refresh rate to 100hz instead of default
60?Hz. Refresh rate listing and dropdown box disappears until setting
monitor resolution to different resolution and back or reboot.
