Back to the problem 
If it is nvidia and an nvidia proprietary driver maybe reinstalling the driver can help. So enter the driver manager in systemsettings switch back to the nouveau driver and restart. Then test it with nouveau just to be sure it is really the graphicsdriver. If it works fine try the driver manager again with the recommend nvidia driver there.
Also just btw. Please use another image uploading website. The one you link to is not save to use without adblocking or on a mobile phone.
