Mouse scroll wheel has stopped working
As of about a week ago, the scroll wheel on mice have stopped working (not just one, all mice). Here's what I've tried to investigate and fix the problem, all to no avail so far:
- Confirmed the problem persists across three mice. One is Corsair, two are Logitech
- Confirmed that all three mice work just fine on other operating systems
- Booted Windows on the same machine and confirmed scroll works, so it's not a hardware problem
-
xinputshows the mouse, including the scroll wheel, and the button map is1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 -
xevdoes not display any event for when the scroll wheel is moved. However, middle mouse click does work just fine. - Restarting the window manager had no effect
- Switching to a different window manager had no effect
- Restarting X had no effect
- Rebooting had no effect
- I have three USB ports, changing to any of them has no effect. Tried switching to a different mouse, same problem. Tried a third mouse, same problem.
- Updated all software and upgraded the kernel
- Searched for answers on Reddit, Super User, Quora, etc. but all the solutions have already been ruled out by the above
- Asked a question on Reddit r/linuxmint but they were no help
Here's some info on what I'm using:
- OS: Linux Mint 18.1
- Kernel: x86-64 Linux 4.10.0-14-generic
- WM: i3, also tried awesome and cinnamon
The biggest issue I see is that xev doesn't show an event and that the problem is consistent across different mice. Again, this problem just popped up a week ago, it had been working without a care for about a year prior. I can't think of any changes that could have caused this in the last days preceding and I'm growing increasingly frustrated.
Any ideas on cause, a fix, what to investigate next?

Update 2: Relevant section of /var/log/Xorg.0.log. To be clear, here the mouse being used is Corsair, but I've also had the same issue with Logitech and Microsoft mice.

Many honest thanks to everyone here and on Reddit, especially @dirkt, for all the help. In the end, I went with the nuclear option: I wiped my root partition and reinstalled Linux. My scrollwheel works flawlessly now, and it fixed a few other problems I was having.
I don't recommend this for most users who run into a problem like this, though it does work. Go through some work trying to fix it before nuking everything (and of course, back up all your data first).
I'm now on Linux Mint 18.2 using the default 4.8 kernel. I can update my question with more information if anyone is curious about what the same command outputs are now.
