I had this problem too with non-working left button mouse(Miscrosoft) and I found out that the reason was that the mute-button was pressed on my Microsoft headset. When the headset is muted the button lights up and the left mouse button pressed and hold down, aka I can use the mute button to select text by pressing mute, move mouse and press button again. So my problem is that the mute button of the headset is wrongly mapped. I guess it should be mapped to the audio mute function. Just like my Logitech keyboard is. If I suspend my computer and wake it again the mute button is turned off on my headset and the left button works again. Also logout and login solves my problem, but the mute button on the headset is still lit.
So my problem was not the mouse it was the headset that interfered. I adding lsusb info for my mouse and headset. ** Attachment added: "lsusb for mouse and headset" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1316873/+attachment/4347846/+files/lsusb.txt -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1316873 Title: Left mouse button stops working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1316873/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
