I am struggling with my left mouse button. Sometimes my left mouse button stops working. It seems randomly. Sometimes after 5 minutes, sometimes everything is okay for 5 hours. Its NOT an hardware issue. I have tested external usb-mouse too, same issue appeard.

I can solve the problem by jumping to text-only console (CTRL-ALT-F1) and going back to graphical desktop.

But after some minutes our hours, same problem appears.

I have tried out different desktops and users too (Gnome, Mate and XFCE). In every desktop-environment, same issue appears.

The left button issue is different from time to time. Sometimes its like my left mouse button is clicked permanently, sometimes it doesnt react to whatever I do. Everything else works fine. (Right mouse button etc.).

I have already tried to solve my problem using google and stackExchange(i.e. this) but everything fixes my problem only for some minutes/hours.

I cant find a permanent solution. Thanks in advance.

Post where I am logging tries and possible solutions


I have exactly the same problem on a Sony Vaio with Xubuntu 16.04, but the left mouse button stops working about every third hour, both on the touchpad and on the external mouse. To date I have been logging out and in again to fix it. Recently I found this alternative.

sudo modprobe -r psmouse
sudo modprobe psmouse proto=imps

Works fine for the external mouse, but the touchpad gets slow and stops scrolling. However, after entering the commands the hanging never bothers me, not even after a full workday.


I found a way to get round this by restaring lightdm .

sudo service lightdm restart

but it's not a fix solution , so each time you have this problem you have to type the command again , so to solve the problem once for all you have to changed lightdm to gdm

sudo apt-get install gdm

  • Nope. I am already using gdm. – julandi Mar 21 '17 at 12:46
