(the context of this question is within virtualbox, but AFAIK it shouldn't really be different)
I have a Microsoft 5-button mouse plugged in, to which scrolling scrolls horizontally. Any ideas?
xinput list:
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ VirtualBox USB Tablet id=8 [slave pointer (2)]
⎜ ↳ ImExPS/2 Generic Explorer Mouse id=10 [slave pointer (2)]
⎜ ↳ (unnamed) id=11 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Sleep Button id=7 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=9 [slave keyboard (3)]
EDIT: This question is a pretty close duplicate of My mouse wheel has stopped scrolling up and down. Could someone possibly mark it as a duplicate?
