Hi,
Running Plasma 5 (5.19.3) on Arch. Works great. Only after waking up from hibernate or sleep Plasma/KWin (?) gets messed up. Occuring issues: activity switching doesn't work anymore, only cursor (no more keyboard entry), missing left information menu/icons in the System Settings (just black). The system is up/alive. I can switch to any TTY and login. Only no more DE and I'm forced to shutdown/reboot. Probably (after searching Forums) it has to do with my NVIDIA card (Geforce GTX 1660 Super OC) running on the latest dkms driver (450.57-2). Any advice is very welcome! Up till then I limit myself to Shutdown (no big issue but still). Thx again, Zach

Hi, great that you want to learn more about working with KDE Plasma. Regards, Zach

Same issues. Thinkpad T15g. I love KDE but if I have to reboot my laptop every time I close the lid, it's unusable.

Same issues on HP ZBook 17 G2. Have you tried Hybrid Sleep? It works for me, but hibernation is a definite reboot every time.
I ran memtest and it shows errors for me.
