asus switch video hotkey

[Nicolò Chieffo]

Binary package hint: acpi-support

asus laptops have a hotkey that lets the user change the video outputs (vga, svideo, lcd).
I'm building a patch to link it to /etc/acpi/videobtn.sh

The patch/fix has been included in the debdiff at bug 193842, and is waiting for sponsorship.
A test package is available from my PPA, if you want to test it (https://launchpad.net/~blueyed/+archive).

Although this bug is marked as "fix released" I'm commenting this.
Some Asus and Samsung notebooks share ACPI features like hotkeys and both are supported
by the asus_laptop kernel module. This report here added an ACPI hotkey event for the Fn+F4
(video switch) combo on my Samsung P35 (ATI Radeon 9700 r300), but there is no effect to the key press.
The situation is as follows:

- key press
- /etc/acpi/events/asus-video
- /etc/acpi/videobtn.sh
- acpi_fakekey $KEY_VIDEOOUT
- KEY_VIDEOOUT maps to 227
- no reaction :(

Which application should handle this event in hardy? Where to look for more hints?
I've written some helper scripts, I can call manually, which efectively do:
  xrandr --output VGA-0 --auto
  xrandr --output LVDS --mode 1280x1024
  xvattr -a XV_CRTC -v 1
or
  xrandr --output VGA-0 --off
  xrandr --output LVDS --mode 1400x1050
  xvattr -a XV_CRTC -v 0

Why is there no general handler for this case? It's hard to switch video-out during run-time and
especially after resume, as there seems to be no automatisation.

[Maybe related report is at bug #212790]

Nikolaus, thanks for reporting about this.
This sounds like bug 217504, please subscribe there and provide any additional info you may have, while trying to keep the bug "in shape" for easy understanding.

Bug 212790 seems to be different: acpi_fakekey does not get triggered (probably) at all.
