[Debian-eeepc-devel] Bug#471521: Bug#471521: vga-toggle.sh: does not do XAUTHORITY dance

Looks like the vga-toogle funtion doesn't know anything 
about XAUTHORITY then because it is started in a subshell. 
Cause that's exactly why there was/is the notify call before 
the vga-toggle in hotkey.sh

Sounds good, yes.

That's sad but there is currently no sane way to do this. 
Look at #462954 for example to see another example of a 
problem detecting the x session this way. Ideally X should 
provide a sane way to get it but we don't know of any yet.

Kind regards
Nico
