This started happening to me as well. I have a Dell optical mouse which was working perfectly, and then one day (after some update), I started having the double-click problem (with a single-click).
I have fixed the problem (temporarily) by changing the mouse to left- hand use, but eventually the other switch will also become worn and I will have to replace the mouse (which works fine in Windows). I like to take a guess as to what is happening: 90% of "mice" do not do an adequate job of switch de-bouncing, and I suspect my mouse is one of those. Probably, after some use (about 2 years) the left-click switch became more noisy, and I started to see this problem. (My system is dual-boot and Windows filters out these "impossible" double clicks-- it is physically impossible for a human to double-click faster than about 200mS.) To fix this, somewhere deep down in the workings of the system (probably at the mouse-driver or maybe in Gnome), there needs to be a setting to ignore double-clicks that happen too fast for them to be created by a human-- (say, 100 to 300 milliseconds or thereabouts). This will filter out "noise" from faulty mice-- (again, about 90% of mice will eventually have this problem, but it can be addressed in software). Windows does a good job of filtering out this noise, and there is no reason why Linux can't do this as well. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/339256 Title: Double mouse click every time I single click -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
