(Note: I intentionally don't fix repeated characters cccaaaaauuuusssssseeeeeedddd by that issue in my message below)
I'm affected by ttthhheeeeee sssssssame issue. Initially I have installed Ubuntu 16.04.4 LTS. While installing it, I had to add ttttthe boot parameter "acpi=off" in grub settings (both for the installer andd for booting of the installed OS). Otherwise, I got a freeze on boot. AAAAaafter installation, I got this probleeemmmm. But next to issues with repeated keys, I got temporary freezes in firefox. I see that sometimes the caret is applicaatioooooonsssss flickers too fast (and that is when I get repeated characters). And other strange issues. I opened a clock application in https://www.online-stopwatch.com/online- clock/ and I saw that the speed offf the "seconds" needle is not regular, and it sometimes moves backwardssss bbbyyyy 10 to 15 seconds. There is really something wrong with system time. Then I have upgraded to Ubuntu 17.10, but it was the same (but I got additional issues because of the upgrade :( ). And the solution was the one from comment #356 from this thread ( https://bugs.launchpad.net/ubuntu/+source/linux/+bug/124406/comments/356 ), which adds a "clocksource=jiffies" boot option. I'm not done yet. Now I have a hang on Ubuntu shutdown ( https://askubuntu.com/questions/764568/ubuntu-16-04-hangs-on-shutdown- restart ), and the suggested solution there is ... forcing acpi in boot options :( I have no idea whether this issue is related my acpi issues. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux 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.
