Hi Raphael,

I've done what you said. The nvidia driver was deinstalled but the Xorg didn't fail when restart (I don't understand because I check with lspci I had only the nvidia card). By the way the background gradation of the login screen was not as usual, as if I had only a few colors.

So I rerun the janitor and reinstall nvidia driver 1.85 from the repo. Every thing is ok with nvidia.
with Intel, the switch-x-to is not anymore in infinite-loop.

the only thing is that glxinfo says:
name of display: :0.0
Xlib:  extension "GLX" missing on display ":0.0".
Xlib:  extension "GLX" missing on display ":0.0".

This is the same thing that when I reinstall my system from scratch. At this step I've created the symbolic link (I will not do this error again):

I don't understand what I'm doing wrong. I'm exactly in the same case when I've resinstalled from scratch.
It's not a big problem (nvidia is ok, and I don't really need glx on intel) but I'm curious to understant what happens.

thanks,

Christophe

Hello Christophe,

i did send this message but one mailserver in the middle seem to be
down, I send it here again with another smtp host:

I see what you manipulated. Why are you not able to solve such easy
things yourself? Simply undo the steps you did..

      * Wrong syntax:
        this will only output the result of dpkg-divert --list to the
        logfile if the two other requests succeed.
        what you where trying to say and what you wanted was this:

        {
                ls -l /usr/lib/libGL*
                ls -l /usr/lib/nvidia/
                dpkg-divert --list
        } > domaklog.txt

      * and wrong procedure!

You should undo your changes, simply fix the diverted symlinks:

To understand what I mean: make a diversion from a symlink and look
where it points to after it was diverted.

the fault lays here:

domak@domakistan-laptop:~$ ll /usr/lib/nvidia/
lrwxrwxrwx 1 root root     21 2009-12-12 18:45 libGL.so.1.xlibmesa -> libGL.so.1.2.xlibmesa

That can not work.

this symlink should not point to libGL.so.1.2.xlibmesa but to
libGL.so.1.2 (which is the original target it points to before it was
diverted, that target should not change after diversion)

simply run

sudo ln -fs libGL.so.1.2 /usr/lib/nvidia/libGL.so.1.xlibmesa

that will fix your personal selfmade problem.

Or you can undo the complete nvidia instalation, create a virgin system
and reinstall everything again:

while in stamina mode:

run the sanitor script and when it asks you if you want to install the
newest driver from nvidia ftp answer with yes, let the script uninstall
all the previous nvidia drivers

reinstall all the intel stuff again:
sudo apt-get install --reinstall xserver-xorg-core libgl1-mesa-glx

(you can check with dpkg-divert --list if the diversions are now
removed)

Next you can begin installing the driver again

      * if you want to install the repo driver, reboot twice without
        acpi_osi in commandline

      * if you want to install the nvidia ftp driver (my recommendation)
        you can simply now reboot in speed mode, the xserver will fail
        (don't be afraid, it MUST fail at this point) and it will tell
        you something about 'Ubuntu is running in Low Graphics mode",
        choose the last option (Comandline) and login, run

                sudo nvsetup

and get happy.

Regards,

Raphael
