Default Black Screen on Ubunto Jaunty - Please Help - No similar threads

Hi,

Apologies in advance if there are similar threads but the ones I looked at did not match.

I have installed Ubuntu Jaunty from scratch on my home made PC. The graphics card is a Gigabyte GeForce 6200 AGP-8x, with DVI and TVOut.

I am having problems getting the Nvidia drivers to work. I have tried the following drivers with varying results:
  1. 180.51 and 180.44 (comes with Ubuntu Jaunty); I get the black screen. Ctrl+Alt+F1 does not respond at all. To recover I have to hard reboot to recover mode and use Xfix to reinstate the generic drivers.
  2. 173.14.18 and 185.18.08 : I get the black screen. CTRL+Alt+F1 responds. I log in in text mode then immediately exit (I do nothing else) and presto I get my Gnome desktop and all seems fine). I adjust the TV-Out etc. using NVidia XServer Settings. I press "Save to X-Configuration File" and I get the following error:
    Code:
    Failed to parse existing X config file '/etc/X11/xorg.conf
    . Alarm bells are ringing.
  3. I am attaching my Nvidia-Bug-Report.Log and my Nvidia-Installer.log
  4. My Nvidia-Installer.log gives the first clue that something is going wrong during the kernel rebuild. Errors are reported indicating that a
    Code:
    Void is used in arithmetic
    several times. I am guessing that some expected items are missing and void is being returned instead. Perhaps libraries are missing.
  5. I continue to investigate and I read
    Code:
    http://uk.download.nvidia.com/XFree86/Linux-x86/180.51/README/chapter-05.html
    which tells me what libraries are required. All looks fine with the exception that
    Code:
    /usr/lib/libGL.so
    is missing. I do have
    Code:
    /usr/lib/libGL.so.1 -> libGL.so.173.14.16
    and
    Code:
    /usr/lib/libGL.so.173.14.16
    . I am guessing that this is not the problem, but would be happy to be told otherwise.
  6. Issuing the command
    Code:
    ldd /usr/X11R6/bin/glxgears
    gives me the following output:
    Code:
    	linux-gate.so.1 =>  (0xb7f79000)
    	libGL.so.1 => /usr/lib/libGL.so.1 (0xb7ec4000)
    	libm.so.6 => /lib/tls/i686/cmov/libm.so.6 (0xb7e9e000)
    	libc.so.6 => /lib/tls/i686/cmov/libc.so.6 (0xb7d3a000)
    	libX11.so.6 => /usr/lib/libX11.so.6 (0xb7c4b000)
    	libGLcore.so.1 => /usr/lib/libGLcore.so.1 (0xb6f0b000)
    	libnvidia-tls.so.1 => /usr/lib/tls/libnvidia-tls.so.1 (0xb6f09000)
    	libXext.so.6 => /usr/lib/libXext.so.6 (0xb6ef9000)
    	libdl.so.2 => /lib/tls/i686/cmov/libdl.so.2 (0xb6ef5000)
    	/lib/ld-linux.so.2 (0xb7f7a000)
    	libxcb.so.1 => /usr/lib/libxcb.so.1 (0xb6eda000)
    	libXau.so.6 => /usr/lib/libXau.so.6 (0xb6ed6000)
    	libXdmcp.so.6 => /usr/lib/libXdmcp.so.6 (0xb6ed1000)
    This is more worrying.

    In summary...

    Expected
    Code:
    libdl.so.2 => /lib/libdl.so.2
    but got
    Code:
    /lib/tls/i686/cmov/libdl.so.2
    Expected
    Code:
    libm.so.6 => /lib/libm.so.6
    but got
    Code:
    libm.so.6 => /lib/tls/i686/cmov/libm.so.6
    Expected
    Code:
    libpthread.so.0 => /lib/libpthread.so.0
    But got nothing.

    Expected
    Code:
    libXp.so.6 => /usr/lib/libXp.so.6
    But got nothing.

    Got the following which I did not expect:
    Code:
    	libXau.so.6 => /usr/lib/libXau.so.6 (0xb6ed6000)
    	libxcb.so.1 => /usr/lib/libxcb.so.1 (0xb6eda000)
    	libXdmcp.so.6 => /usr/lib/libXdmcp.so.6 (0xb6ed1000)
  7. The above implies a Conflicting libraries. Chapter 5 recommends that I either remove these conflicting libraries, or I adjust the ld search path. This is just where it gets a little beyond me and where "tread cautiously" throbs in front of my eyes.

    By removing the conflicting libraries, won't I be rendering something else unusable? The option of adjusting the ld search path looks much more attractive, but now I am at the end of my teather, and feel that I need guidance.

    Can anyone guide me further please? Am I looking in the wrong direction?

    Please help. Any help will be greatly appreciated.
  8. I did look at other threads that mentioned the black screen, but the files that they suggest to modify do not even exist in my system. Another cause for concern?

p/s; I have tried using the UBUNTU provided installers where available, also drivers downloaded straight from NVidia, and using the magic EnvyNG Python tool. The results tend to be the same for each driver regardless of the installation method. Because I am having a problem I have tried to be meticulous in clearing up before trying another method when one fails.

In a nutshell you have to undo everything and start fresh. "Purge" all the nvidia modules / envyng / etc that you installed with Synaptic. Install the ubuntu 'build-essential' package , if it isn't. Download nvidia-xconfig , install it (hint: http://us.download.nvidia.com/XFree8...fig-1.0.tar.gz). Remove any binary drivers you installed with the 'sudo nvidia-installer --uninstall'.There are probably old drivers and messy links still in /usr/lib judging by /usr/lib/libGL.so.1 -> libGL.so.173.14.16. Choose 1 binary driver to install (180.51). Also make sure X(/etc/X11/xorg.conf) is set to load the 'nvidia' driver not 'nv' on startup.

Hi Dizzle7677,

Thank you for your assistance. I followed your instructions to a tee, but unfortunately the same problem still persists.

Any further help from anyone will be greatly appreciated.
