I wanted to create a new custom resolution for my ultrawide monitor, because my graphics card can’t handle UWQH (3440x1440) in most games. I tried modifying my grub files and then updating it via the ‘sudo grub2-mkconfig -o /boot/grub2/grub.cfg’ command. But when I restart, the resolution doesn’t show up in settings.
My specs are:
Kernel Version 6.8.4
Mesa Driver 23.3.6
Fedora Linux 39 with Gnome and Wayland
Rx 6650xt
Amd Ryzen 7 5700x
If I run the command, it shows ‘Found Windows Boot Manager on…’ This is because I dualboot with Windows, could this be the issue? If it is I don’t know how to change it to modifiying Linux.
I also know that you can create a custom resolution with X11, but I want to use Wayland because it looks like Wayland will have better Features in the future and will be used (or is now used) on almost all Distrobutions. I would be happy if someone could help me because I don’t know much about this topic.
Wayland, as I understand it, only allows you to pick resolutions that the monitor supports.
You can try scalling the screen that should result in a lower resolution.
Don’t the games have a config to use a lower resolution in the game?
All the games I play from Steam have this option.
I want to play on 2560x1080, which my monitor supports (works on windows and on x11). Also I can only scale by 200 and 300 which I don’t want. I want to play Minecraft with a shader (which works on 2560x1080 with good performance and lower temperatures). And also it requires the games on steam that the resolution is in settings (I tried it out)
If it supports that resolution then you should be offer it as a choice.
Which desk top are you using?
What does xrandr report are the available modes?
I’m using Gnome if you mean that and Xrandr doesn’t show the resolution I want (it shows it on the bottom because I tried it with X11)
login as wayland and run xrandr it should show the modes the monitor claims to support from its EDID. It should not show your X11 special as you will not be running X11.
I thought that the resolution at the bottom is due to the xrandr commands which I execute when I start my Computer
You must pick one one of the resolutions from the list.
If it is not in the list the monitor does not support it.
Did my suggestion to use scaling work for you?
On a CRT you could add mode lines to change how a multi-scan monitor’s resolution.
But with a digital monitor that is does not work.
Only the modes that the software+hardware in the monitor can map onto the LCD panel in the monitor can be supported.
Onless there is a bug in the monitor all its modes will be defined in the EDID that monitor reports to the GPU.
Yes, it worked, kinda. I can only scale by 200 or 300%. And it doesn’t change how the game is rendered so it renders still at UWQHD. I guess my monitor supports the resolution I want because I can easily do it with Windows and X11
I use KDE Plasma and that can scale in fractions. I use 125% at the moment.
It shows the 2560x1440 resolution. But I want 2560x1080 because I have an ultrawide monitor
On X11 it works perfectly. The Monitor shows 2560x1080, there are no unused pixels and nothing is streched. I don’t know why it doesn’t show up in settings too, and so I posted my problem here
Woah, that’s a lot of questions. I’m quite a noob and new too linux. Ok, I try too answer everything.
I have a Samsung Odyssey G5 Ultrawide Monitor and I did’t update its firmware. I thought it could be done with a USB stick. I updated my resolution on X11 via the xrandr command if you mean that (I don’t really understand modelines, are they just a lines of code?).
If I understand it right what you said, I can overwrite the EDID, which is the information about the monitor. Can I just update my monitors frimware or do I have to do it on linux?
I’m sorry if I did’t answered your questions right, I’m new to linux and there’s much to learn.
Ok, after doing a bit of research I finally understand what EDIDs are. I tried updating my firmware but it seems like I’m on the newest version. I’ll post my output of the command you wrote, but first, I wanted to know, where to put that .bin file. I would be happy if you could help me with this topic, it seems like you are more into linux than me. I think it’s a good chance too learn a bit more about my OS

Ok, so I tried the first steps but I have an problem with edid-generator. If you mean that edid generator (GitHub - akatrevorjay/edid-generator: Hackerswork to generate an EDID blob from given Xorg Modelines, complete with valid checksum.). I switched to its directory and tried the second line from the website. The xorg.conf file didn’t exist so I made one. But that doesn’t work. So I don’t really know how to use edid-generator, could you please explain this? I found no other documentation on how this works. Also I don’t really understand what modelines are
I tried the last part, created an edid folder, but it seems that it did’t work. I’ll post my output from all four commands after this post. Where would the edid file be? Second Question: Where is the edid file which I can copy from kernel? And how to modify it?
