The reason why the brightness notifications work on T60 and newer is that they
have a better ACPI implementation. I'm not really a programmer, but using
bwalex's script as a guide i guess i'll be able to add brightness to the
notification watchlist, so we can have a more lightweight solution for
Thanks everybody for the contributions, it really was a morning surprise
:) I'll try to combine Kees' cycle with dmandell's level checking in the
evening, as i don't have my T42 with me currently. I've been also
thinking how this could be developed to look like an official fix, do
you have any idea
I've created a small script to handle hardware mixer and brightness changes on
Thinkpads. If you start it (perhaps fork it to the background) and change
hardware mixer or brightness levels, you should see a notification pop up with
the appropriate value within 1 sec (yes, i know it's not immedia
This workaround does the trick, but is unfortunately not the prettiest. The
keys on the Thinkpads are controlling the hardware mixer (as Henrique & the
others explained above) and with the old hotkey-setup, your volume buttons will
control the hardware mixer and the software mixer together.
The
Under polling you mean a soft that continuously checks the hardware mixer
levels and sends a message to osd-notify whenever it changes? I'm not a
programmer, but I think this is not a difficult thing to code. I have an IBM
T42, and experienced the above-mentioned problems myself when i updated,
