It is notable to see so much Fujitsu Siemens hardware affected. I have the same issue with the onboard USB 2.0 of a Fujitsu Siemens P710 E90+ Intel i5 3470 desktop computer.
The problem occurs with any of my Varmilo VA88M keyboards, but not with a Cherry Cymotion G-224. The Varmilo keyboards work perfectly fine on any other desktop computer I tested but which happened to be not of the Fujitsu brand. However, only on the Fujitsu Siemens P710, both Varmilo keyboards would very often, but not always, stuck and repeat key combinations like Ctrl+C. This never happened in combination with the Cherry keyboard. So it seems, reproducibility of this issue depends on both the computer and the keyboard hardware. Fed up with this behaviour, I recently installed a NEC USB 2.0 card in its single conventional PCI slot. The problem never reoccurred over the span of two weeks now. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/124406 Title: Keyboard keys get stuck and repeat Status in GNU Emacs: Invalid Status in Linux: Confirmed Status in X.Org X server: In Progress Status in linux package in Ubuntu: Won't Fix Status in xorg-server package in Ubuntu: Won't Fix Status in linux source package in Jaunty: Won't Fix Status in xorg-server source package in Jaunty: Invalid Status in Gentoo Linux: New Bug description: Keyboard keys such as the arrows, Alt-F4, PageUp/PageDown, etc. often get 'stuck' and continue being 'clicked' even after they are physically released. For example when clicking Alt-F4, sometimes it gets stuck so all the windows are closed instead of just one. My configuration is Feisty + Xgl + Compiz Fusion. My previous configuration was Edgy + Xgl + Beryl, where this didn't happen. Others have reported the same problem without using either Xgl or Compiz. The keyboard itself isn't the problem. When dual-booting to Windows, everything works fine. Also, the problem happens with two different keyboards (internal laptop, external USB). My best guess is that the problem occurs at time of high system load. Somehow during these times the key-release signal gets lost and the key-press is repeated indefinitely. This happens more often with Compiz configurations because Compiz tends to increase system load. It also happens more often with power-hungry apps like Firefox and Acrobat Reader for similar reasons. PS: When the keys would repeat all input devices would be locked up. ie. mouse won't move, clicks don't do anything, keyboard presses don't register. Then when it becomes unstuck, the mouse moves around and everything. Hope this helps.
