i had cachyOS installed for a couple of months but was plagued with random system freezes (only hard reset possible, no leads in journalctl). i tracked it down to an issue with the combination of wayland, KDE plasma and the kernel or at least that’s what i could gather from web searches. i had at least one of those freezes per week, often more.
i am now on kubuntu which basically has the same combination of things (wayland and KDE) that should cause the problem but it has been running fine for three weeks, no freezes. so something with the cachy kernel didn’t agree with my system.
i was now told i could use the arch kernel on cachyOS, which was news to me. i tried switching to the cachy LTS kernel but the issue persisted. i now wonder how does the compatibility of the linux kernel work? is it compatible because it is both arch linux? or would the kubuntu kernel also work on cachyOS?
Im having a similar issue on cachyos, but my screen freeze is recoverable by removing the HDMI to external monitor and waiting a bit, then the built in screen will come on and I can plug the HDMI back to continue. I haven’t been able to narrow it down I just write down the time it happens and look at the journalctl but can’t make sense of it
i didn’t try that but does your audio loop the last ~second too? (all my monitors are external)
No for me the audio would keep going like nothing happened. It was just the display that was stuck. Like I could alt tab or switch desktop and the audio would follow correctly and when the screen got unstuck it would be where it should
ah ok, different issue then
