Wow Mike, thanks to your comment I realized I had the exact same problem with my Logitech M210 wireless mouse. I notice that it seems the majority of other reports here also are reported using Logitech mice, so this particular issue may very well be a chronic Logitech mouse problem and not software related at all.
Comments like these make me even more suspicious that this is hardware related and not software related: "Middle button on my M557 BT mouse resumed normal expected functionality, no specific action on my part, even though I could swear it didn't work on firing up the PC this morning." -The faulty switch probably got knocked back into place. "the middle click now occasionally works. I would guess that with the chance of 1/2-1/8 the click works. In the remaining cases it does not." -Since the click can register with extra force, this would explain why a user might see it working sometimes and not others. "The failed mouse device was a "Logitech USB Receiver", USB ID 046d:c517 On runtime I attached another Logitech mouse, USB ID 046d:c52f, running absolutely fine in this regards." -another mouse works fine In sum, I think this issue likely has nothing to do with the Linux kernel or any other package, and may be a candidate for closure. This shouldn't be confused with the mouse scroll issue that John M reported, which does appear to be software related, but that should be filed as a different bug as it has to do with the scrolling function of the wheel and not the middle mouse click. Probably not of interest to anyone, but I am going to try taking my mouse apart to see if I can bend something back into place. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1581088 Title: Middle mouse (wheel-click) button stopped working after upgrade to 16.04 Status in linux package in Ubuntu: Confirmed Bug description: Since upgrading to 16.04 clicking the middle mouse button (scroll wheel) on my Logitech M185 stopped working. xev does not even show the event for clicking the wheel, while it shows other button clicks and scroll wheel up/down events. xinput list shows the USB receiver 2 times: ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ Logitech USB Receiver id=9 [slave pointer (2)] ⎜ ↳ Logitech USB Receiver id=10 [slave pointer (2)] ⎜ ↳ HID 046a:0023 id=13 [slave pointer (2)] ⎜ ↳ SynPS/2 Synaptics TouchPad id=16 [slave pointer (2)] ⎜ ↳ TPPS/2 IBM TrackPoint id=17 [slave pointer (2)] Listing the capabilities looks like this: $ xinput list 9 Logitech USB Receiver id=9 [slave pointer (2)] Reporting 7 classes: Class originated from: 9.
