   Hi, 
	   Has anyone seen XFreeX86 1.2 loose characters and mouse events?
   I am running with pccons and patchkit 0.2.1, and I am not using the
   kernals that they provided. Also I am having problems with the 
   state of the control key. If you hit ^C or something sometimes the
   state of the control key gets stuck in the down position. If you depress
   control the keyboard behaves normally again. Lastly backspace doesn't work
   after a while. If I do stty < /dev/tty it says 

   ...
   erase
   ^H


	   Could someone please enlighten me as to what my problem is?

This can be a symtom of a process other than the X xerver reading the
keyboard or mouse port and stealing characters from the input stream.
I've seen it happen when both getty and xdm are unintentionally run at
the same time.  getty steals what characters it can and the server
gets the leftovers.  Since the keyboard is sending raw up/down key
events, getty can steal just the control up or control down event.
