I got the same problem. This appeared when I did an update in 15.04. I thought that upgrading to 15.10 would solve the problem. So on and so forth.
I gave it a little test. If you know your mouse device in 'xinput --list' try to test it with xinput --test %id%' where %id% is your mouse device id in xinput. Leave that test run in a terminal window and open another terminal. In the second terminal cat the device input file into the terminal. On my system it's /dev/input/mouse0. Get the mouse events to stream into the terminal with 'sudo cat /dev/input/mouse0'. Just to be clear, try these commands in two separate terminals: xinput --test %id% sudo cat /dev/input/mouse0 You'll notice that your mouse motions appear in both terminals in addition to the right button clicks. As for the left bottom clicks. Keep clicking the left mouse button and you'll notice that both terminals won't show the input event every now and then. If this turns out to be the case for a lot of users that experience this problem. The error would have to be in the system and driver processes. As for the broken mouse button. My mouse works fine in another installation of ubuntu 13.4? or 14.4? It's a wireless mouse and keyboard that connects to the usb port. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1316873 Title: Left mouse button stops working Status in xorg package in Ubuntu: Expired Bug description: This problem has plagued me for a few years across different laptops and Ubuntu versions. Current I am experiencing this on a Dell Inspiron 15z running Ubuntu 14.04 LTS. It typically starts after I have used the chat or call feature in gmail, by clicking on the phone icon in the left chat margin. I am a Firefox user and have not tested this with chrome etc. It has not happened if i dont install google-talkplugin so it is quite possible that the plugin is to blame. Symptom ======= The left mouse button on all attached mice - USB , Trackpad and touch - will not do anything .... however the right mouse button continues to work. This happens to all applications and also to the desktop. The keyboard continues to function as normal. When this occurs , my solution is to Alt-F4 close all windows and log out of the X session. When I re-login the left mouse button works as normal. This is an irritant and work disruptor as I have to save all browser and desktop applications to safe state before I logout to reset the mouse. I will appreciate any soltion or workaround.
