The mute button of my Thinkpad SL510 is no longer working in Maverick with Kernel 2.6.35.
In Lucid it didn't produce an "XF86AudioMute" signal either but at least it muted the notebook's speakers (not the headphones) and illuminated it's led when pressed. Now with Maverick it doesn't work at all.
Also the brightness controls don't work properly. Ubuntu's indicator OSD already is at it's left end when medium brightness is set. If i lower the brightness any further it starts over at it's right end. So from highest to lowest brightness, the OSD runs through twice.
