Hi,
My external monitor has a graphical glitch after an update to Zorin OS 17.3 Pro. See attachement. Linux version: 6.8.0-57-generic. I have propriety NVIDIA metapackage version 550 installed.
This often happens after I lock-out and log-in again. Any ideas?
Kind regards
Filip
Yes, that is a Nvidia glitch. I have seen this happen, before.
I recommend several steps.
First, please ID for us which Nvidia card you are using.
Welcome to the Forum!
Does Your System run in Wayland or X11/Xorg? You can check that in Settings>About. If there should stand Wayland, try it with switching to Xorg.
to do that, go to the Login Screen (not the Lock screen). Simply reboot for that. On the Login Screen, click on Your Profile so that the Password field appears. It has to be appeared. When it is appeared, You should see a Gear Icon in the bottom right Corner. Click on it and choose the Option ''Zorin Desktop on Xorg'' and then log in and check if it works.
Another Option could be to try a different Nvidia Driver. For this, first uninstall the existing Driver with:
sudo apt purge nvidia*
Then install the Driver with:
sudo apt install nvidia-driver-[Driver-Version] nvidia-dkms-[Driver-Version]
For [Driver-Version] choose the Number of the Driver. For Example: 535, 550 or 570.
And it would be good to know what Nvidia Card You use and how the Monitor is connected.
Tried the switch to Xorg, it seems to have resolved it for now when I log-out and log-in again. So thanks for that. I will mark this for now as the solution.
