Resolution dropped from 1600*1200 to 1024*768 after updating from 19.04 to 19.10

Question

I was using Ubuntu 19.04 and everything was fine. yesterday I updated to 19.10. There was no problem after rebooting. Today for some reason after I booted my computer, the resolution dropped from 1600*1200 to 1024*768. I tried restarting it again but it is still the same. 1024*768 is the highest resolution in the display settings now. I tried to add the 1600*1200 again manually using these steps but the image was shifted to the left and slightly up. I could barely see the dock and the top bar because of that. And of course there were black margins on the right and the bottom. Here is the output from inxi -Fz for the system specs
