Recently, I've been having exactly the same issue with my keyboard. I do not know if it's after a recent kernel update.
# uname -a Linux basaidai 3.5.0-28-generic #48-Ubuntu SMP Tue Apr 23 23:03:38 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux Anyone else having the issue recently? I am not using KDE or anything, just a clean 12.04 Ubuntu with Compiz. Keyboard seems very sluggish after resume. I need to press hard on keys and type very slow in order for keys to come in to the OS. This looks like a Kernel bug. ** Attachment added: "dmesg" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/227359/+attachment/3675580/+files/dmesg -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/227359 Title: suddenly keyboard event recognition gets really slow after multiple suspend/resumes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/227359/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
