I have installed Debian 8 and xfce. My machine is Lenovo Ideapad 500S. There's no information for this machine on how to properly use Debian on it.

When I install linux-image-4.4.0-trunk-amd64 and reboot to start from that kernel, nothing appears.

Getting to the terminal and trying to do startx or restart the service lightdm doesn't work. X server gives up. lightdm status said something got failed.

500S has GeForce 940M. Nvidia homepage suggests installing 352.79 driver. It doesn't work. Even crashes X when booting on original kernel. Also tried to install nvidia-driver package and let them handle it. No changes. still got black screen on 4.4.0 kernel booting.

What should I do?

    Please add the detailed error messages Xorg and lightdm gave you. – Johnson Steward Feb 16 '16 at 4:00

I don't still know how to use nvidia-driver on the kernel, but I at least succeed on successfully booting the computer with x server working.

After installing the kernel, edit /etc/default/grub and add nomodeset in the line with GRUB_CMDLINE_LINUX_DEFAULT.


Save the file, and do

sudo update-grub

Still it seems like there's a problem unsolved as I see something like [ Failed ] on a boot log when booting up the computer. But it work at least. :(
