I was having all kinds of problems but couldn't solve or even repeat them. They seemed to come and go which meant they never really quit. One was when I closed Konsole I'd have a CPU stuck at 100% and Dolphin did it sometimes, too. I had a flickering desktop when two windows were opened on top of each other after resuming from suspend. Before sleep, it was ok and restarting kwin_x11 fixed it. I used a small script on the desktop and just double clicked it after waking it up. This was better than logging out and back in.
- Code: Select all
#!/bin/bash
/usr/bin/kwin_x11 --replace &
I removed my Nvidia GTX 760 and installed an AMD RX 580 and everything is fixed. I don't know how a Nvidia driver causes a stuck core when closing Konsole, but it sure appears changing the card fixed it. I haven't had a problem in a few days and this includes in Mageia 6 and Suse Tumbleweed. Tumbleweed hasn't been updated in months, it's for testing and working on Mageia if I break it. In Tumbleweed I removed the Nvidia driver and installed the open source driver, AMDGPU, and then over wrote xorg.conf with xorg.conf.install which was created at initial install. When I was able to boot into Tumbleweed, I double checked and everything seemed to be ok and I still didn't update it.
Mageia was much less trouble to get going. I removed the Nvidia driver and shutdown then changed the card and rebooted and it detected the new card and just worked. I gave you the driver details to point out that I didn't change anything that wasn't driver related and it fixed everything on both distros, so Nvidia is causing serious problems. I was using whatever the current Nvidia driver was in Mageia 6, nothing custom or anything. I hope this helps some of you.
