In my Ubuntu 20.04.3 LTS the resolution always stuck at 640x480. I can change resolution with xrandr after login but as I start computer again it come back at 640x480. I don't want to use xrandr again and agian. Is there any different way to change resolution to 1024x768 permanently?
When booting I saw this error may be it is related to this issue :
