--- Comment #15 from Zéfling <zefling at ikilote.net> ---
I also have this problem with a 770 GTX since I switched to KDE 5 about 5
months ago. Freeze without reason learns exept the mouse cursor. 
Kubuntu 17.10, Kubuntu 18.4, Debian 9 KDE and KDE Neon, same problem. In
addition, with the nVidia driver it's worse.
