I switched to Xubuntu from windows and things have been pretty smooth until I tried to connect another monitor to my laptop (using vga). The screen suddenly went black, and since then, even with my external monitor disconnected, all I see is a black screen after I enter the login details. I can use the guest account to login without any problems.
I looked around before posting and found the exact same problem and the solution there was to delete this file
/.config/xfce4/xfconf/xfce-perchannel-xml/displays.xml, but unfortunately that file doesn't seem to exist in my pc.
