Thank you for the feedback. Good to know it works well for someone else.
I think we'll need to wait for the Foundation to release a more general interface for X-windows to do that, I'm afraid. As it is fortunately a DPI interface(with a D2A attached) the Foundation may be trying to do 2 things in one go, as what they do for DSI may be almost directly applicable to DPI
I'd like to run joan
's PISCOPE application on VGA666, but it needs GTK+ which in turns needs X, so I'll have to wait.
There's still a useful amount of things one can do now though.
Whilst typing this on a Pi2, "hello_teapot" is displaying on the other attached screen, vga666, with a total cpu usage of 2%
I've converted a couple of "hello_pi" applications, along with a basic slideshow application to use vga666 (or HDMI - just supply the display number as an argument to the application).
So even now, more than just omxplayer is practical.
Having the DPI available as a separate display is very useful. Kiosk displays can run 2 independent AV displays from 1 RPi, at better quality than composite. It's useful when testing GPU programs, because you can see the result on VGA, & edit the code displayed on the HDMI screen, without the display being obliterated by the GPU output.
There are so many cheap & second hand VGA displays & build times are decent now on RPi2, so not so much a need for another computer to SSH into RPi. I bought a second-hand vga monitor last year for a quarter of the cost of RPi, so it's in keeping with RPi's low cost philosophy
