I am using Ubuntu 15.10. I accidentally changed the size of the interface to maximum. Now my folders and windows are too large and don't fully fit the screen so I cannot revert the effect. Is there any way to reset the display settings to default so this can revert to normal?
~/.config/monitors.xml should do it:
- Open a terminal window by pressing Ctrl+Alt+T
rm ~/.config/monitors.xmland press Enter
- immediately log out and back in. It should be reverted now
If you know what resolution your screen supports (e.g.
1440x900), you can run the command:
xrandr -s 1440x900
to at least temporarily set a workable solution, then subsequently change settings from GUI.
I had a similar problem to you but I found the solution here How to scale title bars and menu in Ubuntu 14.04 with the terminal only
dconf reset /com/ubuntu/user-interface/scale-factor
This changes the "scale for menu and title bars" to default.
