I'm hoping someone might have gone through this exact issue and can help me.
The volume wheel on my laptop no longer works under mint kde --> seeing as it worked fine under Ubuntu but not under Kubuntu it must be something in kde right? I'm sure if it worked in one distro there must be a way to enable it here. Most of my reading online points me to Keyboard Layout or Keyboard Shortcuts in kcontrol but I'm not sure what to do in there.
Alternatively, I can live without the wheel as long as I can enable some keys as volume control shortcuts. It just plains sucks having to use the gui everytime to adjust the volume when watching a dvd.
