It does indeed seem that the switching back and forth between text and

probably did do this (but didn't include this in my recipe above) - so
here is a new 'recipe' that shows the problem (for me)
boot to run level 3
if not root, then make sure /dev/console is writeable
login and type:
setterm -blank 0
start X
type into an xterm:
while true; do echo "" > /dev/console; usleep 100000; done
while the above loop is running switch to the text console and back
again (Ctrl-Alt-F1 then Ctrl-Alt-F7)
... and the screen will be shifting (and wrapping) to the left.
Okay, this makes me see the problem more clearly. It looks like that
vt/console layer is unreliable in terms of checking for the
text/graphics mode of the current console. Instead of auditing the
console code, I'll just have vgacon check for the mode. Try the
attached patch and let me know if it helps.
That seems to fix it!
Thanks
