The problem is little complicated and don’t know how to start lol.
Okay. So I installed latest version of Manjaro with Gnome. And the main problem is - Manjaro works correctly on FHD screen but when I switched back (via cable) to my 2k display GUI not work.
I can open TTY. Tried switch resolution via
xrandr but on 2k screen I got
Can't open screen..
For example. When I start Manjaro on FHD display, turn youtube playlist and switch back to 2k display - system still works.
I had this problem on Arch (march iso) too. And no. This is not the problem with cable because week ago I had Debian based distro (ParrotOS) and works correctly on 2k resolution.
My PC have Radeon graphic card so this is not the classical Nvidia problem.
