Comment 33 for bug 261318

Thanks Andy. Reporting back on a Toshiba Portege R100:

* toshset now works for what I use it for: switching the external VGA on
and off, and changing the LCD backlight brightness. Very good. Definitely
more fun than having to edit xorg.conf and restart X for such changes.

* A number of fn keys work: sound mute/unmute, display brightness up and
down. The volume up and down fn keys don't work, but I suspect that will
just require some local tinkering... or possibly undoing local tinkering
that I've already done incorrectly!

* I didn't notice any regressions, e.g. suspend to RAM still works (I'm
guessing there's some ACPI help for it).

Let me know if you'd like me to prod anything else.

As an aside I note that if I change the LCD backlight brightness with the
fn keys, my display zooms into the top-left 640x480 (?) of the screen (as
it would when pressing fn-spacebar under Windows). Doing a VT shuffle in
and out of X fixes the issue. Using toshset to change the LCD backlight
brightness does not cause the zooming effect, however. After suspend to
RAM, though, the fn-key LCD backlight change is not causing zooming,
although I note that video reverted to the LCD only (but toshset -video
both brought back the CRT output successfully). FWIW I think I fixed this
problem under Debian by changing the boot-time kernel video parameter...
(but of course I can't remember exactly what I did previously)
