Fn Keys & Brightness


Hi everyone!

I have Mandrake 10.0 on my Toshiba 5205-s505 running 99%, the 1% left is the problem with the Fn Keys, specially the brightness ones (up - down). I have installed the FnFx, but doesn't work.

Any ideas, i will appreciated so much


Thanks


Edgar

I found that I can type
Code:
setbrightness xxx
at the command prompt on my Sony to dim the screen substituting a value, say 150 for xxx. It's part of ACPI, I think. So, you'll need an ACPI kernel installed. Let us know if the same command works on your Toshiba.

Thanks Dennisk, but it don't work at all. I re-compile the kernel undex /usr/src/linux with the toshiba module, but i don't see the module /etc/acpi/toshiba, i don't know if i made the right compilation process.

The FnFx give me the same error, that i don't have the Toshiba ACPI module enable. But really, now i am more confused.

Here's a script that I use under Fedora Core 2 to control the brightness and fan. It expects that you have /proc/acpi/toshiba, however.

#!/bin/sh
TOSHIBA=/proc/acpi/toshiba


case "$1" in
low)
echo "Setting brightness to low"
echo "Setting fan to auto"

echo "force_on: 0" >$TOSHIBA/fan
echo "brightness: 2" >$TOSHIBA/lcd
;;

medium)
echo "Setting brightness to medium"
echo "Setting fan to auto"

echo "force_on: 0" >$TOSHIBA/fan
echo "brightness: 4" >$TOSHIBA/lcd
;;

high)
echo "Setting brightness to high"
echo "Forcing fan on"

echo "force_on: 1" >$TOSHIBA/fan
echo "brightness: 7" >$TOSHIBA/lcd
;;

*)
echo "Usage: $0 (low|medium|high)"
exit 1
esac

Hope this helps.

The hotkeys can be read from /proc/acpi/toshiba/keys I don't know if there's a more efficient way.

Do you have problems with your touchpad being erratic sometimes? Occasionally, when I touch the pad to move the cursor, the mouse pointer jumps across the screen. It's kind of annoying.
