[SLUG] dropping to console from X problem ##

[Minh Van <mle@xxxxxxxxxxxxxxxx>]

i have a problem with X. i can't press ctrl-alt-F<> key sequence to drop
to a console -- i mean, it does drop to a console ... but the display
doesn't reset the current X screen to the switched console screen. i have
to type things in blind. it's like dropping to a console screen with a
permanent screen capture of the current X screen.

eg. 

if tty10 was in X, and i switched to tty15 with ctrl-alt-f5, linux will
invisibly place me in/at a tty15 console, but with a frozen tty10 X
screen-capture.
