HDMI connected monitor stopped being recognized by linux mint

Post by MintCondition »

I have been using linux mint for over a month(recently switched from windows) and everything was working as expected and all of a sudden the monitor isn't being recognized. I have verified that the monitor is working just fine and that the cable is good as well.

I tried to boot linux mint from usb and there its being recognized, but its not from the installed version.

below is the output of inxi -Fxz and grep HDMI /var/log/Xorg.0.log
