[Bug 1483629] Middle mouse emulation failed on Thinkpad t520
https://bugzilla.redhat.com/show_bug.cgi?id=1483629
--- Comment #4 from Peter Rathlev <peter(a)rathlev.dk> ---
I'm also on a Thinkpad, though a T530 (specifically model 24295ZG). So it's
probably specific to Thinkpad.
Agree that it's not Blender. And good thing to rename the bug, but I don't
think it's emulation failing. Emulation (when using left+right lower mouse
buttons, those that belong to the touchpad) actually works, whereas the
physical middle mouse button (upper buttons, between the spacebar and the
touchpad) does not. Maybe it could be called "Middle mouse button fails on
Thinpad T520/T530"?
It tested installing "xorg-x11-drv-synaptics-legacy" and that does not seem to
make a difference to this problem, though the touchpad does seem to handle a
bit better.
I have perused the Lenovo forum thread and it doesn't look like the same
problem to me. In this case everything except the physical middle mouse button
works, and the problems seems to be that the "press" event is held back until
the button is released, at which point it arrives together with the "release"
event. And this is seen with "xev"; testing with "evtest" from a text
VTY shows
events arriving as expected, "press" on button down and "release" on
button up.
