From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Custom refresh rate on KDE wayland (lemmy.world)

I'm running KDE wayland with proprietary Nvidia drivers on CachyOS, so far I haven't found a way to set a custom monitor refresh rate, on windows I could use the Nvidia control panel to make one (going from 60hz to 75hz). kscreen-doctor doesn't let you set "unsupported" modes, the kernel launch option of video=1920x1080@75 didn't work, somehow. So how would I do it?

That is what xrandr allows you to do on X11, create and set display modes that aren't reported by the monitor.

EDID editing is basically replacing the data reported by the monitor, which also allows you to add display modes it doesn't report itself. This is the only way to do what you are looking for on wayland.

You can either switch to X11, and use xrandr, or create an EDID file with the display mode you want, and have it load on boot. Doing that is unfortunately not simple.
