Bug 431411

SUMMARY


STEPS TO REPRODUCE
1. mouse copy sample text
2. press middle button
3. nothing pasted

OBSERVED RESULT

My middle mouse button can't event , middle button cannot paste the selected text.
I've configured middle button in konsole, gnome-tweaks, and it doesn't work

My kde version 5.20.3 ... you can see below

Operating System: Fedora 33
KDE Plasma Version: 5.20.3
KDE Frameworks Version: 5.75.0
Qt Version: 5.15.2
Kernel Version: 5.9.14
OS Type: 64-bit
And xinput,

$ xinput --list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ Logitech Wireless Keyboard PID:4023 id=8 [slave pointer (2)]
⎜ ↳ Logitech Wireless Mouse id=9 [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)]
↳ Power Button id=7 [slave keyboard (3)]
↳ Logitech Wireless Keyboard PID:4023 id=10 [slave keyboard (3)]
Checking in another way, I was surprised because,

$ xev | grep button
state 0x10, button 1, same_screen YES
state 0x110, button 1, same_screen YES
state 0x10, button 3, same_screen YES
state 0x410, button 3, same_screen YES
state 0x10, button 1, same_screen YES
state 0x110, button 1, same_screen YES
but, NO event pressed middle button !



and using libinput, same problem


$ libinput list-devices

and then,

$libinput debug-events --device /dev/input/event3
