Status in mutter package in Ubuntu:
New
Bug description:
I have 2 monitors a 2K monitor (2560x1440) and a 4k monitor
(3840x2160) both 27inch
Obviously to extend display correctly (join displays) I need to put my
4k monitor at scale of 125 and 2K monitor at 100% scale.
I arrange two monitors side by side, then select 125% on 4K monitor
(Fractional scaling is on) and click apply, both my monitors go to
wrong scaling 2K goes to 50% and 4K goes to 200% and displays arrange
bottom and top of each other.
also login appears on wrong monitor (secondary) instead of selected
primary
