I just updated to Kubuntu 17.10 from 17.04. During the initial install, the desktop would not load. After some work in the root shell (including using dpkg to fix some issues, I got the desktop GUI back up.

Now, the screen seems to be flickering and hanging at random intervals, and seemingly just with the focused application. As I write this, the entire screen will freeze from time to time, save for the mouse cursor.

Is anyone else experiencing a similar issue?

I had found this one on AskUbuntu and it worked for me on 16.04:

Ubuntu 15.10 and 16.04 keep freezing randomly

I have applied it on Kubuntu and stopped freezing at all but get from time to time freeze but gets back again. I hope this helps.
