Can't change Gnome* but I did find a repair guide for the mouse on ifixit because they are the best.

*probably can, probably too lazy
very cute Corsair. Can't get a screwdriver in to these recessed screws
*drill*
There we go.
Please notify next of kin* the mouse may not survive the procedure.

can't really recommend looking inside keyboards and mice via microscope
Feel better about the patient's chances. The scrollwheel contains the seeds of its own demise. The axle material has flaked off a bit into the button, presumably obstructing the electrical connection inside. Compressed air may help. Can somewhat see it here. White on left is plastic axle, resting on blue button. Magnification is ~20x
Isn't this interesting?
Patient is in recovery.
Scrollwheel click works but not at 100%. Plastic flakes in the button? Button worn out? Space monkeys?
I'm in the market for another mouse.
