:)
I get a similar problem with :
nvidia tnt2 64
mandrake 8.1 or 8.0
not always but occasionaly (with or without FB)
no DRI (not for nvidia)
X server crashes when i flip from X -> text tty -> X again
then "text mode" consoles are displayed in the vidmode i was in in X
sometimes causing garbage on the screen (green/red characters)
I have no idea what could cause this ...

I've got a similar situation with an identical card and linux distro.
I can repeatably freeze the console with the following procedure:
startx from the console, with no window manager, only launching an xterm.
log in to another virtual console as the same user you started X as, 'export
DISPLAY=:0.0'; and start a window manager (actually, any X client, I think).
switch back to the graphical console (should now be displaying a window
manager), and kill the xterm (ctrl-d).
switch to the virtual console where I started the window manager, and kill
the window manager.
at this point the console hangs; displaying a blank (tho not dark) screen.
attempting to switch to any virtual console results in the rendering of a
series of short, vertical (mostly red & green) lines at the top of the
screen. machine is still active, and I can SSH in
Greg, can you try doing this, and see if it happens on your machine as well?
It doesn't happen to me if I don't load the DRI stuff. I've tested this with
kernel 2.4.9-ac3, 2.4.14, and 2.4.16.
I don't have framebuffer support in my kernel; as someone on #dri suggested
removing it to see if it fixes another DRI lockup problem (after playing
Half-Life [under wine] or Rune [from loki] for some time, the screen will
hang).
I actually never got console framebuffer working with my G450... hung every
time, with the early 2.4 kernels I tried.
I submitted a lengthy and detailed bug report to [EMAIL PROTECTED]; is it
appropriate to repost it here? (I'm new to this list).
Care Soderstrom.
