Dual monitors - disable laptop monitor

I have an added external monitor in addition to the laptop monitor.

I would like to disable or turn off the laptop monitor and just use the external monitor.


I think it depends on what kind of video card you are using.
So it it will be helpful to include the kind of video card it is
and the version of openSUSE in your post.

Use xrandr to turn the output on and off (if the laptop is anything older then about a year, its mostly the LDVS output you’re after; if its a very recent vintage, then very possible its an eDP output) … if you don’t want to use cli, then anyone of the gui frontends for it should do this … (you never mentioned what desktop environment you are using, but) if you were using KDE 4.11, then the newly introduced kscreen should allow you to do this simply by cycling through the key combo your laptop uses to evoke video outputs
