Blank Screen after installing Kernel 2.6

[sminons]

tried installing the linux 2.6 test 10 kernel. After compiling and installing the new new kernel (kerneltrap.org/node/view/799), when I try to boot, all I get is a blank screen. The same happened when I tried installing the test 9, 2.6 kernel. What is wrong ?. Am I missing something?

Do you have all the stuff you need in Console Drivers ?

VGA text console
Video mode selection support

(And framebuffer if you prefer that)

[sminons]

How do I check that?

[Hayl]

make menuconfig

when you are in the directory that has your kernel's source code, then scroll down to the section with teh console driver stuff and look.

[sminons]

I had enabled all the options, but still the same. I get a blank screen when the new kernel boots.

What kind of mother board? Chipset? etc. You may even post the config file you are trying to use (relevant parts)

I don't think the standard nvidia drivers work with 2.6... that could be the prob.

do not enable the framebuffer...

please post your /etc/lilo.conf , you grub.conf and your kernel config (.config in top level source directory)

Make sure your .config has
CONFIG_INPUT=y, CONFIG_VT=y, CONFIG_VGA_CONSOLE=y and CONFIG_VT_CONSOLE=y
A lot of people have discovered that taking their .config from 2.4 and
running make oldconfig to pick up new options leads to problems, notably
with CONFIG_VT not being set.

according to the halloween document:

I have seen the same on several of the 2.6.0-testXX's

Try disabling all of the Framebuffer drivers except "VGA 16 colors" and "VESA VGA".

This should work. It did for me.
