My mouse wheel seems to have (suddenly) stopped working and will not
scroll. Anyone come across this? Help much appreciated.
Run xev and the scroll the wheel and check the output.
You should see something like this:
ButtonPress event, serial 32, synthetic NO, window 0x2c00001,
root 0x557, subw 0x0, time 45498783, (88,110), root:(400,614),
state 0x10, button 4, same_screen YES
ButtonRelease event, serial 32, synthetic NO, window 0x2c00001,
root 0x557, subw 0x0, time 45498783, (88,110), root:(400,614),
state 0x810, button 4, same_screen YES
ButtonPress event, serial 32, synthetic NO, window 0x2c00001,
root 0x557, subw 0x0, time 45500535, (88,110), root:(400,614),
state 0x10, button 5, same_screen YES
ButtonRelease event, serial 32, synthetic NO, window 0x2c00001,
root 0x557, subw 0x0, time 45500535, (88,110), root:(400,614),
state 0x1010, button 5, same_screen YES
If that occurs, the mouse itself is working.
