after installing nouveau-firmware, keyboard doesnt work in X

[robbie]

Binary package hint: nouveau-firmware

the behavior is actually rather intricate. if I replug in the keyboard at the login screen, I can log in. but once the session starts the same trick wont get it to work. at all times the number pad itself works, as does the caps lock, and ctl+alt+backspace works, but backspace alone does not (except as noted at the login screen). neither does ctl+alt+f# .. If I switch to c+a+f3 the keyboard works fine, but then Im not in x.

there is no failure message specific to a keyboard in gdm/:0.log after plugging in the keyboard or after logging in, and I see two message-blocks for the keyboard ataching and detaching.

importantly: Uninstalling nouveau-firmware DID NOT REVERT the system to its previous working state.
I consider that a major issue. :)

I'm on UBuntu 10.10, on a powerpc G5 (no live disk to revert to, because of the well-preserved bug with that disk image). I can only check in every so often, as this basically hosed my home pc. please be precise if you ask me to gather any information or follow any suggested remedy.

I have reinstalled the entire xserver-xorg* subsystem and ubuntu-desktop, and continued to play with nouveau until now I have nouveau working (had to install the 2.6.35 kernel and some mesa-gli, and create an xorg.conf file). The keyboard works in all environments except gnome after unplugging and replugging.

even in gnome, changing the input manager (for example, from None to ibus) makes the keyboard function for a tiny length of time .. but one-two seconds later it will stop working again.
