I'm using Linux Mint mate edition. I often connect an external monitor to my laptop by VGA. When the system boots up without VGA connected, I get login screen. After I type my password and continue, I get no display at all. I have to connect the external monitor to see what's happening. Ctrl +alt +f1 doesn't bring up any display. If I login with a different user, everything's fine. I tried deleting ~.config/monitors.xml and rebooting.
Now can anyone explain me how to get my laptop's main display back to work? It's really annoying. Without external monitor I'm completely blind.
I was following this post but couldn't find any solution. https://askubuntu.com/questions/148725/laptop-screen-blank-after-login-when-external-monitor-is-not-connected
