How to Use Dual Display on Linux

I have KDE 4 and use the NVIDIA video drivers (I configured with 'nvidia-xconfig --no-logo --composite'). I tried plugging my computer into a projector and pushing fn+f4 which is supposed to enable dual display so the projector can show the video, but it didn't work. Does anyone know how to do it? Thanks in advance!!

Try

man xrandr

It's the most basic solution to multi-screen layouts I know of. Served me quite well in several presentations.

Or since you use Nvidia, you could run nvidia-settings and set it up from there.

Re: How to Use Dual Display on Linux

Whenever you run nividia-settings the settings are temporaryily stored i.e. You can't write it into the file. So, the right way would be to

sudo nvidia-settings

Now you can write to the file and ur settings are permanent


How I'm learning linux : If it ain't broken, fix it until it is. Then start over again.

Always useful to have an external monitor to test it out first. Make sure the resolution is the same as the one advertised by the projector.
