With new install (12.04) I confirm this problem. I can simply unplug keyboard and then re-plug and all is then well.
Serious problem as we cannot always be doing this every time we switch on computer. With PS/2 connection no problem, just with the USB. Consequence - cannot login in. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/990870 Title: External USB keyboard not working in Ubuntu 12.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/990870/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
