Back in the 'old days' you could just specify which X11 display you wanted to open your window on ...

export DISPLAY=:0.0

That would be for the default first screen typically.

Then you could run your windowed apps from the serial console/remote shell and they'd pop up on the desired display.  Modern linux seams to have more layers of security, but on the gumstix everything runs as root so this would be the first thing I'd try.  (Disclaimer: I only have headless gumstix's running here now so I can't give this a quick try myself and then not post this if it doesn't work.) :-)

Anyone ever try this combination? I can run a PyGTK on the XFCE desktop, but

try that, PyGTK barfs because it doesn't know what to display itself on. Has
anyone ever figured out how to launch a PyGTK (or even regular GTK) windowed
app from a serial console?

Get your SQL database under version control now!
Version control is standard for application code, but databases havent
caught up. So what steps can you take to put your SQL databases under
version control? Why should you start doing it? Read more to find out.
