This sounds like it is the same bug as here: https://bugs.launchpad.net/ubuntu/+source/casper/+bug/107516
and here: http://bugzilla.kernel.org/show_bug.cgi?id=8246 Try adding ec_intr=0 to your kernel options in grub. For me this made everything more responsive but it is only a workaround. If this works for you guys then this bug should probably be marked as a duplicate. Unfortunately none of these bugs seem to have much activity so any extra information that can be supplied will probably be helpful. -- ThinkPad R40e Keyboard/Mouse/Trackpoint regularly unresponsive on Feisty Release https://bugs.launchpad.net/bugs/107859 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
