PS: An interesting things is that I select the new kernel 2.6.29, why can I boot from kernel 2.6.27 without eselect kernel set * again? anything wrong here?
This is normal, ensure that your video drivers are correct with:

Code: Select all

eselect opengl set nvidia
and reboot.
It's been already at that option.
I am a bit confused, why I set the kernel at 2.6.29 (eselect kernel set), I still can boot using the 2.6.27 from the grub?

Because the selected kernel is just for "working" with it, when you will emerge/install packages or modules,
they will be installed for that kernel; I think that your problem is in graphic drivers, if you have a Nvidia, as far
as I know, there can be only one installed Nvidia driver in the system, Nvidia doesn't allow multiple drivers for
more kernels.
If the system boots fine with kernel 2.6.27 this means that your drivers are for that kernel, or that you are not
using proprietary drivers... at least this is what I'm thinking.
Could you check which version you have with:

Code: Select all

equo query installed nvidia

there are three entries rather than one, that explain why I can boot.

Code: Select all

You could try to remove the old nvidia module (nvidia-settings is just the GUI used to configure the
video settings), eselect again the nvidia opengl implementation and reboot.
Be careful, if it won't work you will not be able to boot in the old kernel, at least not using the Nvidia drivers.

To do remove the old modules you should do this:

Code: Select all

equo remove --ask "x11-drivers/nvidia-drivers-185.18.14#2.6.27-sabayon"
then eselect nvidia opengl:

Code: Select all

eselect opengl set nvidia
and reboot.

If this fails, login as root in text mode and eselect xorg-x11.

Code: Select all

eselect opengl set xorg-x11
and reboot, this will allow to you to have at least the GUI and recover the old
Nvidia drivers.

Thanks for your kind help!!
I have tried to remove the x11-drivers/nvidia-drivers-185.18.14#2.6.27-sabayon, and leave only the nvidia-drivers for 2.6.29, it still not works. furthermore, I tried the live CD sabayon - gnome 4.2 which is using the kernel 2.6.29, then it got into the same situation. It might be because the kernel 2.6.29 is not compitiable with my machine?

Hi,
A question to all the kind people helping, I honestly do not know the correct answer.

All through this thread.. I have not read that the op has booted the .29 kernel to eselect the kernel or opengl
I may have missed it but....
Is it possible to boot the .27 kernel and have these changes effect the .29 kernel?

If so, I would equo install the latest nvidia driver even though it is listed as installed...so were 2 others.
But eselect opengl set "xorg" would also get a gui as mica suggested

another option might be to add a cheat code at grub to boot .29

Hi, all

it still cannot work, even the cheat code. I remember last time I did not select the right video driver with the kernel
I still can get a tty console and run until the x-window tell me failed to load the driver.
but this time it is too strange, it doesn't show anything, moreover, i didn't observe any disk reading.

This worked for me (a total ignoramus):

su

equo install linux-sabayon
(did "modprobe -r nvidia" but not sure if it had any or important effect)
equo install nvidia (this will suggest what to write instead of just nvidia)
