OK, just to confuse matters: For the above description, I was using the mouse left-handed. I described right and left buttons according to function on the computer, i.e. what I called the right button, which invokes a context menu, is physically the one on the left. This raises the same event (button 3) as occurs when I press a special key. I'd forgotten that left-handed is the exception until just now.
When testing the same thing with the mouse right-handed, a special key fires a button 1 press event. In other words, whichever hand the mouse is set for, it signals a 'press' corresponding to the physical-left button. As before, there's no corresponding ButtonRelease, so it's as if that button is 'held down'. I hope this helps someone to understand what might be causing this behaviour. -- Keyboard special keys interfere with mouse https://bugs.launchpad.net/bugs/636311 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-input-evdev in ubuntu. _______________________________________________ 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
