During the installation I made a mistake and selected that my mouse was of type PS/2 instead of USB which is the correct type. When I later started X the mouse wouldn't work, nothing strange about that since I chose the wrong type. What's strange is that the keyboard didn't work. I rebooted and ran XConfigurator, and when XConfigurator starts X to check the configuration I got the same thing. Neither the mouse nor the keyboard worked. When X exited and I got back to XConfigurator I found that the keyboard didn't work even _after_ X exited. Seems like X is trying to detect the PS/2 mouse and screws up the keyboard by sending some weird data to it or something.
This defect is considered SHOULD-FIX for Fairfax.
What mouse (brand/model) do you have? Also, what keyboard do you have? Is your keyboard PS/2, AT, or USB? This problem is sufficiently bizarre IMHO that I need much more detailed information. Can you create an X server log by running X configurator, and then attaching /var/log/XFree*.log (all of em) to this report? Please attach your configuration file as well, and a copy of your /var/log/messages (trimmed if necessary to be <= 200k or so, we just want the bottom of it preferably with kernel boot messages). Also, are you using a Red Hat binary kernel, or a home built kernel?
Closing bug due to lack of information.
