Hello! I am on Fedora 40 KDE Edition (Wayland). I have monitor with two supported refresh rates (60, 50 Hz). How can I set custom refresh rate? I know, on Windows you can use CRU.

in case you have not solved it, it’s easy on Sway. man sway-output (kinda) tells you how to do it. Here’s an example sway config line:

output HDMI-1 res --custom 1921x1081@61Hz

You can even change CRT timings like front porch, if you want that.

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.
