External monitor on X250 runing Linux

I'm runing the Devuan OS on an X250 and need to hook it up to a projector. None of the discussion on line has been of any help.

So far have been using a VGA cable and booting with it connected. The result is a blank screen The Fn-F7 buton does nothing, which I gather I must expect. I have no desktop environment. The xerandx -d :1:0, -d :0.1 etc. command fails to recognize the monitor, although of course -d :0.0 does the laptop's display.

Re: External monitor on X250 runing Linux

Hi! Officially this model is tested to work with Ubuntu 14.04 as per this link: https://support.lenovo.com/us/en/solutions/pd031426. Since the display driver you're asking is form a different distributor, you can check it from the links highlighted on the picture below.

Re: External monitor on X250 runing Linux

I did not understand the advice I was given. It assumed that the display driver I am using was not native. It is native to devian/devuan. Do I need a different display driver to get Fn-F7 to select external display options. I suspect I can user randr utility to do it, but do not know how. If I simply need a differenrt display driver to get the Fn-F7 key to work, what is is or where do I get it?
