I use the nv driver in XFree and the vesafb for the framebuffer console.
vesafb works fine, I get the bootlogo and all during boot.
Once X11 starts up and I want to switch back to the framebuffer
console using CTRL-ALT-F1, the framebuffer is garbled. The screen is
flickering, as if the vertical synchronisation is lost. Colors seem to
be OK, I get grey garbage on black background.
Switching back to X11 using ALT-F7 works OK, the X11 screen looks fine.
I made two screenshots to illuminate what I'm seeing:

(watch out, high resolution)
It's not entirely clear if it's an issue of the nv driver or the vesafb
in the kernel.

I have a similar problem. With open source nv and vesafb the virtual terminal
looks like this if I switch back to the framebuffer:

Everything is moved to the left, the right area is repeated some time and
fills the rest of the screen.
As binary nvidia module works without this problem I support it's a problem of
nv...

You're way better of than I am, since you can SEE something.

Same here, the binary nvidia module doesn't give me that problem.
So it's nv, and probably OT for lkml. Sorry for the noise, guys.
