Confirmed here as well with bluetooth keyboard and with mouse clicks. The bluetooth keyboard shows doubles on input however types and responds just fine. The mouse however does cause issues within the system on clicking. Simple usb Logitec M100 mouse.
Kernel 3.2.0-32-generic lsusb Bus 002 Device 006: ID 046d:c05a Logitech, Inc. Optical Mouse M90 Mouse Click/release output xev output `xev | grep Button` ButtonPress event, serial 33, synthetic NO, window 0x4c00001, ButtonRelease event, serial 33, synthetic NO, window 0x4c00001, Keyboard Press output `xev | grep Key` KeyPress event, serial 36, synthetic NO, window 0x4c00001, KeyRelease event, serial 36, synthetic NO, window 0x4c00001, annoying. Just tried this with an older mouse and the double-click problem has not happened once; however I did note the xev output is identical `xev | grep Button` ButtonPress event, serial 33, synthetic NO, window 0x5600001, ButtonRelease event, serial 33, synthetic NO, window 0x5600001, I believe this is a hardware problem based on the evidence from above coupled with the feedback from the http://ubuntuforums.org/showthread.php?t=1429091&page=2 mice manufacturers focus on speed, and thus new mice spit the output out much faster then older mice..... of course I don't have much to substantiate this claim; so at this point it's mere opinion. Ultimately this hardware "bug" should be dealt with by the o/s though and a mere measure implimented to determine that a human doesn't double click in mere milliseconds. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-input-evdev in Ubuntu. https://bugs.launchpad.net/bugs/365300 Title: Randomly I get double clicks when I do a single click. Status in “xserver-xorg-input-evdev” package in Ubuntu: Confirmed Status in “xserver-xorg-input-evdev” package in Arch Linux: New Bug description: Binary package hint: xserver-xorg-input-mouse Description: Ubuntu 9.04 Release: 9.04 apt-cache policy xserver-xorg-input-mouse xserver-xorg-input-mouse: Instalado: 1:1.4.0-1 Candidato: 1:1.4.0-1 Tabela de Versão: *** 1:1.4.0-1 0 500 http://archive.ubuntu.com jaunty/main Packages 100 /var/lib/dpkg/status What I expected was: Single Click. What happens: Mouse double clicks. This bug applies to the base operating system and all software installed on my system. Randomly the mouse responds with two mouse clicks when I click only once. Witch turns my system unusable: I try to close a windows, and the system closes that windows, and the one below. I try to right click something and the system right clicks and executes one of the menu options.. Etc.. Etc... When this problem happens during some time, then it disappears, then It comes back. The behaviour of the bug seems perfectly random to me. It is more frequent with the right button, than with the left one. Plus, this isn't an hardware fault because it doesn't happen in other operating systems. This is the 'xev' command output where you can see the erratic behaviour of the mouse. I single clicked two times, one of them was recorded by 'xev' as a single click, the second one was recorded as a double click.
