The problem I’m facing is that my Kubuntu 20.04 does randomly lock screen. At this moment I could found any pattern to explain the random lock screen. This has been happening in my computer for 2 months when I had Kubuntu 18.04 and it’s still happening despite I’ve upgraded to 20.04 (thought that upgrading the dist could solve it).
Lock, Log out and Switch User works perfectly, meaninig that after a randomly lock I can log in again without problem and all the programs still open.
I’ve dual boot Kubuntu and Window 10 and I can confirm that this does not happen in Windows, so I discard a hardware problem. ¿Any command to know which process are interfering wiht my lock screen?
