I'm fairly new to Ubuntu. I'm using a mouse with two extra thumb buttons and I figured it would be handy to use them for volume control.
After googling around a bit I ended here: Configuring mouse buttons to switch between apps? Decided to try it out (first with the example for switching apps to see if that worked).
So I wrote "xdotool key alt+Tab" b:9 + Release in a file called .xbindkeysrc
I ran xbindkeys -v -n in the terminal, which seemed to work, however the mouse button did nothing. Upon closing and running again, I now got a warning too stating that there is some other program controlling the mouse buttons.
Upon using the command xev, which normally shows the number of the mouse button upon clicking in a white square, the ninth button didn't show 'button 9', instead it gave 'mode NotifyGrab, detail NotifyVirtual'
Any advice on how I can make it work the way I need to? Thanks a lot!
