If anyone else runs into my issue, try using the -c mode (v1.1 compliant, no requirement for multiples of 60Hz; v1.2 modelines weren’t accepted by my U28e590ds) from this cvt calculator: https://github.com/kevinlekiller/cvt_modeline_calculator_12/blob/master/README.md
I could not follow the instructions . if I checked the name for the monitor I ended up with “DP-2”…
after some hours of google I found this page: https://nvidia.custhelp.com/app/answers/detail/a_id/3571/~/managing-a-display-edid-on-linux
(Works on Ubuntu 19.10 , so probably every version )
there are some hints to figure out the correct name , mine was “DFP-2” for example and also a more “nice” way of editing the Xconf file.
like this:
sudo nvidia-xconfig --custom-edid="GPU-0.DFP-3:/home/nvidia/edid-alien.txt
hope it helps someone
Come on guys, what about AMD on Linux please? We all know that AMD has far better and proper open-source Linux support. Surely this is possible on a Ryzen system with a AMD R9 290 and a Debian Buster distro called MX19. How can I grab and extract the EDID on MX19 on a AMD based system please?
You know its strange, under windows I can configure my 40" Qnix 4k freesync screen to have a freesync range of 35-60 (default is hilariously bad 48-65), but under LINUX if I configure a custom edid with that range for freesync, it causes major flickering and even in some cases blackouts in games.
Keeping in mind I’m using a NVIDAI 1080TI VRR compat mode so maybe that has something to do with it? wondering what the result will be once i move back to a AMD GPU.
Has anyone else had issues with freesync ranges working under windows but not under Linux (due to flicker etc) ?
Hello i put my hz on 87 same number i have on windows but it blacked screen wnd now every time i try to run PopOs it just black screens for a while and then restarts and boots into 10
