X11 Screwed 2??

Hi All,

If  you folks search - there is already one post by the heading "X11 Screwed".

I am cont. from there but in a different process altogether.

Lets imagine you are trying to install Nvidia driver for your Debian.

Nvidia driver installation will be discussed in some other post.

So you install nvidia driver and it messes up X.

The process complicates from here.

You should either know how to uninstall nvidia drivers or to just allow them and modprobe the XF86 drivers.

Lets here discuss just about reinstalling XF86 drivers. And take the other one some time later.

Follow these steps:

1. lsmod | grep nvidia
This has to output some values.

If 1 above has no output - then it means to say that nvidia driver has not been installed properly.   

2. lsmod | grep nvidia \ | nv \ | vesa \ | vga

This 2 has to output some values.

If there are no values for this as well, then it is simple as the last post.

Next try to search for nvidia-glx or nv or nvidia in the /proc/modules file

cat /proc/modules | grep nvidia-glx \| nv \ | nvidia

If you get any of the 3 values here - it is as simple as a modprobe command.

Last Resort

Reinstall XF86 drivers. But before that try doing this:

dpkg-reconfigure -phigh xserver-xorg


If you get the X screen - then its yippeee... or last'est'

As said in the last post - if you have a fast internet connection, update your sources.list file to your nearest mirror and issue this:

apt-get update; apt-get install xserver-xorg

Let me know for any issues...

Mail me at

Take care,
Ananth Gouri
