First, press ctrl + F10 to lock mouse to dosbox and then try alt + Enter.

I think the Alt-Enter command makes DOSBox go full-screen. That might not be your problem, though.

  • Goto /home/user/dosbox.conf
  • Find resolution
  • Change fullresolution from original to your choice (eg. fullresolution=640x480)
  • Leave windowresolution intact (i.e, windowresolution=original) as you might want a smaller sized window.

Optional: change fullscreen to true (i.e, fullscreen=true) if you want to start dosbox in fullscreen mode
