I had Debian Lenny working 100% with my Lenovo 3000 N200 laptop. All keys working flawlessly.
Then I accidentally removed myself from all groups with usermod. To fix things (like having no sound, since I removed myself from audio group) I asked someone which groups he was part of and then added myself to them.
I now have audio back, but the sound keys are not working as expected. They even popup up volume control window and the volume bar moves, but that has no effect. It's like if that window is associated with a different mixer.
alsamixer works and so does Gnome's sound applet.
I want to make them work back as they were before I messed my groups.
