Mouse Driver Problem?
 

I have recently installed on a desktop PC Slackware 14.2 (64-bit) with a KDE desktop environment.

Sometimes when I click on an icon in the bottom panel nothing happens. The mouse pointer stays in the shape of an arrow instead of changing into the shape of a hand with the index finger out. And so nothing else happens...

I have a Logitech M315 wireless mouse that is paired to a USB dongle.

When initially setting up Slackware I picked "USB connected mouse" within the mouse configuration window. I did not see any other choice that would better apply to my mouse.

Anybody knows what is going on here?

If it were me, the first thing I would try is plugging in a wired mouse and seeing whether it is sensed and whether it works properly.

I think the kernel manages the connection to the mouse.

Also, I found this article. It might help: https://github.com/sriemer/fix-linux-mouse
