how to reset the text mode?

[Mario Olimpio de Menezes <mario@curiango.ipen.br>]

Hi,

	I have a box which had its text console frozen by some X app.
The screen froze on exiting from fvwm95 and nothing works since then:
can't switch to VT using Crtl+Alt+Fn or kill X using Crtl+Alt+Backspace. 
	My only solution was to start xdm from another machine so that I
can log in locally. 
	Now, I can have fvwm95 running again, but VT aren't usable. They
are frozen with pieces of fvwm95 screen and other patterns.
	How can I reset the text mode console so that my VT (F1-F6) get
usable again? I tried kill -HUP pid_of_getty but didn't help. 
	I can even login in the VT but reset didn't help. The screen is
rock frozen.
	Any suggestion?
	Thanks.
