Kubuntu Gutsy Gibbon / Feisty Fawn on a Thinkpad R61e

[mindcrime]

Hello all,

Can someone tell me how to get the brightness keys to work (Fn + PgUp and Fn + PgDn) on Kubuntu gutsy or feisty. The current file's contents are:

Code: Select all

cat /etc/acpi/video_brightnessdown.sh
#!/bin/bash
. /usr/share/acpi-support/key-constants
acpi_fakekey $KEY_BRIGHTNESSDOWN

and when I press the keys, nothing happens.

Thanks

The brightness control does not seem to be completely worked out yet. Which video chipset do you have? There seems to be a little more progress in the Nvidia camp than the ATI camp.

That's strange I'm running Kubuntu Feisty Fawn, with ATI drivers,
on a T42p and the brightness keys worked out of the box.

My graphics chipset is:

Code: Select all

 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c)

Suspend is working but when I come back from a suspended state, the brightness drops to near zero and there is no way to restore it to normal. Can you even imagine why this problem seems to be occurring? By the way, I am running a custom 2.6.20-15 kernel which supports hdaps and has tp_smapi.

Thanks

That is because you have a T42p. I have a T60 that works fine also but my R61 does not work at all. Newer graphics chips are not as well supported as older chips are at this point, it will come along.

mindcrime, My R61 has the Nvidia Quadros 140m chip and although the brightness keys do not work I do not have the resume from suspend issue that you do. Better drivers will come along soon to hopefully resolve all issues. Sorry I can't be more help.
