This is a Dell Studio 15xx series notebook. Just tried with a USB external keyboard and that works fine. When hitting 2 keys at once both keys are reported on screen, and no sticking.
Still, given everything else listed in symptoms it seems it would have to be an X bug, since console and other OS works fine. -- xorg key events not registering causing missed keypresses and sticking key repeats https://bugs.launchpad.net/bugs/371066 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
