?

xrandr lists two screens, DP-1 & DP-2
but Settings -> display lists only one screen: Screen 1

Strange. That should show the same. Install lxrandr and try that instead.

Like the output from xrandr, lxrandr sees two screens and allows the resolutions to be set individually. However it does not have any options to use the two screens as one desktop, they are just mirrored and no option to do anything else.

Yes, you're right, lxrandr doesn't support that apparently. I thought it did, sorry.

Open sourcery and install arandr. That will do it. Make sure you refresh the slackbuild cache if you don't find the package in the list at first.

Thats it works fine, thanks.
