Hi. After recent update my middle mouse button stopped working in every program. Scrolling still works. I dual boot Windows on the same machine and MMB works there, so it’s not a hardware issue.
I use XFCE, but I’m not sure if this is a DE related problem, so I’ve posted it in general Support.
The only idea I have
is to check and rule out whether the mouse button is actually working or maybe just coincidentally physically broken
use the command:
xev
every movement and every button press and release should generate a response
If it is not already installed:
pamac install xorg-xev
Thank you.
xev doesn’t notice MMB click. I could use Timeshift to make sure the MMB not working was caused by the update.
In that case my diagnosis would be:
it’s broken - physically/electrically not working anymore
… the switch gave up the ghost … it happens …
If the button doesn’t generate a response in xev
no amount of software timeshift can fix it 
But it works well enough on Windows on the same machine, using the same mouse.
It is not physically broken then - but if it isn’t
I have no bright idea why it wouldn’t respond in xev
Sorry!
Someone else might know how to diagnose this further.
Or maybe timeshift can help.
It’s easier though to simply boot a live system and see whether it works there, like it does in Windows.
I’m sorry. It was a hardware issue after all. It just started working and then stopped again on Manjaro. And checking once again on Windows, it doesn’t work.
Thank you and I apologise for wasting your time.
