Created attachment 465594 [details] xorg-server log file I have only one keyboard and one mouse. Sometimes the X-server gets into a state where pressing the left mouse button generates two ButtonPress/ButtonRelease events for a single press/release: ButtonPress event, serial 40, synthetic NO, window 0x5a00001, root 0x4b9, subw 0x0, time 80885247, (55,108), root:(1959,165), state 0x0, button 1, same_screen YES ButtonRelease event, serial 40, synthetic NO, window 0x5a00001, root 0x4b9, subw 0x0, time 80885295, (55,108), root:(1959,165), state 0x100, button 1, same_screen YES ButtonPress event, serial 40, synthetic NO, window 0x5a00001, root 0x4b9, subw 0x0, time 80885310, (55,108), root:(1959,165), state 0x0, button 1, same_screen YES ButtonRelease event, serial 40, synthetic NO, window 0x5a00001, root 0x4b9, subw 0x0, time 80885342, (55,108), root:(1959,165), state 0x100, button 1, same_screen YES Once it gets in this state, maybe the duplicate events happen 1/3 of the time. It comes and goes. I only see this for the left mouse button. When I press and hold the left mouse button and release only after several seconds, then the duplicate Press/Release sequence comes after the first Release: ButtonPress event, serial 40, synthetic NO, window 0x5a00001, root 0x4b9, subw 0x0, time 81126422, (114,108), root:(2018,165), state 0x0, button 1, same_screen YES ButtonRelease event, serial 40, synthetic NO, window 0x5a00001, root 0x4b9, subw 0x0, time 81128158, (114,108), root:(2018,165), state 0x100, button 1, same_screen YES ButtonPress event, serial 40, synthetic NO, window 0x5a00001, root 0x4b9, subw 0x0, time 81128166, (114,108), root:(2018,165), state 0x0, button 1, same_screen YES ButtonRelease event, serial 40, synthetic NO, window 0x5a00001, root 0x4b9, subw 0x0, time 81128182, (114,108), root:(2018,165), state 0x100, button 1, same_screen YES Note the times of the last 3 are all close together. I don't think this is a hardware issue, because I am not the first person to report this (http://superuser.com/questions/750818/x11-evdev-mouse-generates-duplicate-events). This report was from 2014. I also have had this happen before years ago on the same system as today (maybe around 2014), but eventually it went away (I upgrade packages frequently). I recently did a major system upgrade.

I have absolutely no idea what the problem might be, but I doubt it's the kind of thing a distribution will be able to solve... Okay, you're using libinput. That's good. Please file a bug upstream: https://bugs.freedesktop.org/enter_bug.cgi?product=xorg&component=Input/libinput and link us to it.
Filed upstream. https://bugs.freedesktop.org/show_bug.cgi?id=100057 Thanks.
Upstream bug is RESOLVED/WONTFIX. Please reopen if something changes.
