I think it's kwin and/or xorg which is causing this problem. Sometimes, what seems to be "random", my whole desktop just freezes up. I can't move the mouse and the keyboard doesn't do anything. I can't switch to any TTY and if I press the power button on my computer nothing happens. The only way I can get out is if I hold the power button. I've had an idea to SSH in and try to kill X to see if that would help, but I've forgot the wifi-password for the network, so I could never do it.

I almost always have cmus running in the background, and it works fine. It plays music, as it should. It even plays the next song in the playlist. I think it's kwin because I have conky running, and kwin usually uses 0-1% of my CPU, but last time it froze it (along with Xorg.bin) went up to 6%.

I'm running KDE 5.8.0 and xorg 1.17.1-4 (catalyst requires an older version of xorg) on Arch Linux.

if the mouse cursor freezes it means that it's X or even lower. The best thing is to try to get the ssh to work again.

Thanks for the guide, I got SSH working now. I'll report results when the next freeze happens (hopefully it won't).

But please do NOT post on this (freeze in X11 or the kernel) problem there (enough diversion already
