ThinkVantage Button Stopped Working

[wolke]

I have a Lenovo ThinkPad W520. The ThinkVantage button worked perfectly fine. xev gave it the sym XF86_Launch1, which I bound to gnome-terminal.

I installed the proprietary nvidia driver for the quatro 1000 it came with, and the thinkvantage button wouldnt work on boot. xev doesnt appear to receive it at all. Volume up/down/mute all work fine. The microphone mute button also stopped working {it reported something or other in xev and now nothing}.

Im gonna reboot with integrated gfx and see what happens.

booting with integrated graphics enabled in bios completely fixes the issue. so, the nvidia driver appears to be causing the issue. WEIRD, i want my terminal button baaaack.

and no brightness control either! again, with integrated graphics selected, brightness works like a charm.

Has anyone resolved this issue?

I'm facing the same problem with kubuntu 11.10 on a Thinkpad T410.

I have the same issue with Thinkpad T61 and the NVidai proprietary drivers. With the NVidia drivers enabled all function key and special buttons work except the thinkvantage button. With the nouveau driver the thinkvantage button works. I think that this is a relatively old issue. For me the problem first appeared with the 260.x.x series of drivers but i never bothered to find a solution.

EDIT:

I have found a bug report for the issue - http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=613534
