Blank Screen after new Kernel only on boot! KDE ok, system works

[fraujansen]

Hi!
I have installed new kernel and now I see only a blank screen while the boot process. The system works, because after this "invisible" boot my PC starts KDE without problems....
When I am in KDE I can't switch to the Terminals with CTRL+ALT+F1,2,3... etc...
It seems like my kernel/pc/graphiccard doesnt support something....
FB? to much colors in console-mode? what can I change in my kernelconfig?
I thought it was the bootlogo option... but it isn't.
any help?
please maybe also to daniel.schiller@gmail.com? thank you very mcuh

What distribution are you using? Is your default runlevel set to 5? What graphics card do you have, and have you reinstalled the drivers for it? (You'll need to do this after a kernel upgrade.)

Debian unstable
Kernel 2.6.14
with NVIDIA GeForce4 Ti4400
but this problem was also with Ati Radeon 7200 maybe? don´t know...

I think is something in kernelconfig, framebuffer? console-something? video-mode?
now I´m at work but later I think post my dmesg or boot.log or kernelconfig... I think it says more...
thank u 4 reading!

You didn't answer my other question. What is your default runlevel set to? (You can find this out in your /etc/inittab file.) If it's 5, then you're booting to graphical mode which *might* be what's causing your weird blackout problem. Try changing it to 3. The line you're looking for looks something like this:
