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.

Help! Random 1-2 second freezes (lemm.ee)

EDIT: The solution was that it was freesync. Turned it off on my monitor, and that fixed it.

I recently picked up a used RX 6600xt, and ever since the screen will occasionally freeze for 1-2 seconds before returning to normal. As far as I can tell, input and sound work as normal during these. There's no real pattern either.

I'm on Mint 21.3 Cinnamon, on the 6.5 kernel (there was a sleep related issue for me in the default kernel version). Since getting the GPU, I've replaced the CPU and motherboard.

Any guesses as to what this might be, or where to look? I tried checking mint's logs app and there didn't seem to be anything associated with it.

Just a hunch but I'd look into rtkit. A bad process with realtime priority could starve out others.

Temporarily disable rtkit and log out.

I vaguely know rtkit handles thread/process priority... could there be any possible issues if I disable it?

Edit: actually have a more important question: how do I disable rtkit? It seems to just start up regardless of what I do.

The only important instance I know of would be your audio server (pipewire, pulse) which could also explain why audio continues to work.

Masking the service should do it.
