I recently installed KDE-neon 5.20 and screen display freezes ramdomly.

The only workaround is to restart my system.


  • Graphics Processor: GeForce GTX 750 Ti/PCIe/SSE2
  • model : GM107 [GeForce GTX 750 Ti]
  • vendor : NVIDIA Corporation

How to fix that?


This solution worked well for me :

$ sudo add-apt-repository ppa:graphics-drivers/ppa
$ sudo apt-get update
$ sudo ubuntu-drivers autoinstall

Now, reboot your system
