I think I have an idea what to include in ibm-videobtn:
-action=/bin/true
+action=xrandr --auto
Just checking, does it work if you replace it by
action=/etc/acpi/videobtn.sh
? This is what all other video buttons do, and I am of course hoping
that we can consolidate this. :-)
However this does not best way to do it, but it works and maybe it is
better than /bin/true.
This will only switch on the second display if is already connected, it
won't switch off unless disconnected.
Some further ideas:
Make an external script which toggles between:
switch off VGA: xrandr --output VGA --off
switch off internal display: xrandr --output LVDS --off
Detect if a xrandr aware video card is present (works with intel, not
sure about the others).
I think "xrandr --auto" is simple and safe enought.
If this is needed, I think the "switch explicitly" option is probably
better, because I can think of some real use cases where you don't want
to disconnect the external monitor but you _do_ want to keep your
display to yourself. For instance, if you have a TV that automatically
switches to a certain input if it detects a signal (mine does that). Or
if you're preparing for a presentation, you might want to connect and
test the output and then switch back to only the internal display until
you've finished preparing. Furthermore, if you want xrandr --auto, you
really make users expect real autodetection, which we can't do. Better
to keep it with the usual behaviour for these kinds of buttons. :-)
If someone have the resources to write the external script, the better.
I'd definitely move this to an external script. Not much resources
required, but testing would be nice if it's implemented. If you would
like to help, I'd much appreciate it.
Cheers,
Bart
