Booting the kernel with parameter acpi=off resolved the problem for me. I had exactly the same problem as described above: Keyboard worked fine with Edgy. After an upgrade to Feisty the keyboard worked in Grub, but neither on the console nor in X.
I noticed that in /proc/bus/input/devices veraious power and sleep buttons are listed with the kbd driver as handler. Maybe I should add, that my motherboard is rather old and doesn't support ACPI properly. This workaround may resolve similar problems with PS/2 mice, too (e.g. bug 108382). -- PS/2 Keyboards Not Responding https://bugs.launchpad.net/bugs/106289 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
