Yesterday I booted up Ubuntu 18.04, only to find out that the resolution is extremely low and the system lags a lot, it even glitches out a bit sometimes. I've tried rebooting several times with no luck. I'm running on a 1920x1080 144hz monitor and RTX 2060 with the 415.27 driver installed. The CPU is i7 8700K if that's relevant at all.
There wasn't any problem with the GPU/driver previously and the system ran smoothly on the highest graphics settings. The only change I made to the system that I could recall is installing the no-IP DDNS dynamic update client, which I hardly think would be the culprit. I also force shut down two times before the problem occurred.
P.S. I have Ubuntu installed alongside Windows 10 and the latter appears to be fine and unaffected.
