Default flickering virtual-console, after X was started

Salut folks,
I use the 4191 driver on a GeForce2go (Acer 634LC). With X there is everything allright, by now ;-). When I start into textmode, I get a nice virtual-console (my boot-vga-mode is 788). After starting X I may temporarily switch back to one of the virtual consoles, or permanently, by terminating X. I all cases the text-mode is flickering as my screenshot shows. Did I do something wrong?
For my XF86config you may look at

Thanks
hartwig ;-)

You're going to have to either focus that camera or not enlarge the bitmap. Try taking another picture, this time in focus, and repost it (the edges of the monitor, BTW, are the giveaway that the camera or the resizing are the problem). Don't scale it up, either.

Your XF86Config-4 should have nothing to do with the problem.

But it seems so... Who is responsible for restaurating the right graphics-mode when X terminates, or when there is a switch form X to a virual console?
The point is, that befor you start the X-Server, the virtual console looks as it should, without any flickering. The problem only occours after X has been started.

Umm, the kernel. Specifically, the console driver.

If you're running a hi-res console (framebuffer console is what the kernel config calls it, I think), check into the fbcon.c file, specifically the fbcon_switch() function. It's in linux/drivers/video/fbcon.c.

Or, if you use the default RH virtual console setup, then before you start X up, hit Ctrl-Alt-F7 (actually, I'm pretty sure Ctrl-F7 would work, but I'm in the habit of using Ctrl-Alt because that's the only thing that works when you're currently looking at an X screen) once. You'll see a blank screen, as long as X is configured to start on that VC. Hit Ctrl-F1 and startx. The VC switch that you just saw happened somewhere in the fbcon driver.

The thing is, X runs entirely on top of the VC layer, AFAIK.
