Ok so I apology not to test and report it at first, but here is some important informations :
-My problem triggered when upgrade ubuntu last friday 10 June. Before, I used Natty KDE for few weeks without any hitch. -I use my old usb Logitech wire-mouse, G5, when I plug it out the laptop touchpad runs perfectly. When I plug it in, both (touchpad & mouse) won't take left clicks. Of course I tested the mouse on Mac, it works perefectly. My problem's behaviour is extacly like this one, so I thought it would be related ! Anyway, I found a way to finally use again my lovely Ubuntu, which I was missing a lot since. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/505494 Title: Mouse events fail frequently and unpredictably, requiring kwin restart To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-evdev/+bug/505494/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
