    Default Install 11.4 Video Unreadable Except For Safe Mode

    My old desktop had a power supply that was going bad, so instead of replacing it again I decided to buy a new PC Desktop. So I ordered from TigerDirect.com and got a grodd AMD computer without a operating system on it as I didn't want that Windows 7 scheisse on it. So I downloaded SuSe 11.4 64 bit, and installed it last night.

    At this point I will tell you the new PC has an NVIDIA GeForce 61100 GPU for graphics with 128 mb memory. Also I use an HP W2007 wide display monitor running 1680 by 1050 resolution, that I got over 3 years ago when I was running SuSe 10.2.

    So during installation last night of 11.4 when it did the first boot after install, is when I first saw the symptom which is an illegible white screen, with about 100 3 mm lines on it. So I shut down, rebooted and brought it up safe mode and all is fine. The error screen only appears if I boot GRUB with the Desktop or Xen option and only when the boot would switch to display my desktop.

    I recall a similar illegible video monitor issue when I first got the display over 3 years ago, and fixed it by changing a SuSe video configuration option, but being I am getting old and I didn't write down what the configuration file was I am at a loss. All my previous SuSe installations never had a problem as I would always choose the Update rather than new install option thus that configuration file was brought across the many releases installations. This video configuration parameter had the monitor resolution sizes in it.

    So if someone could help me I would greatly appreciate it.

    Probably the file you are thinking of is /etc/X11/xorg.conf ... but I don't know what to tell you to put in there.

    What happens if you boot the 'desktop' option with the 'nomodeset' boot option? Have you had the chance to install the proprietary nvidia driver?

    Thanks for the reply, ok that is the file xorg.conf living in etc/X11 directory. When I get back to this system I will try editing it.
    How do you boot with nomodeset option, do you have to set something in GRUB manager?
    Have not yet installed any NVIDIA drivers, I will look into that.

    I went to the nvidia.com site and downloaded the 6100 driver, and discovered the readme file which contained amongst other thongs the following:

    Chapter 6. Configuring X for the NVIDIA Driver
    Prev Part I. Installation and Configuration Instructions Next
    Chapter 6. Configuring X for the NVIDIA Driver

    Table of Contents

    Using nvidia-xconfig to configure the X server
    Manually Editing the Configuration File

    The X configuration file provides a means to configure the X server. This section describes the settings necessary to enable the NVIDIA driver. A comprehensive list of parameters is provided in Appendix B, X Config Options.

    The NVIDIA Driver includes a utility called nvidia-xconfig, which is designed to make editing the X configuration file easy. You can also edit it by hand.
    Using nvidia-xconfig to configure the X server

    nvidia-xconfig will find the X configuration file and modify it to use the NVIDIA X driver. In most cases, you can simply answer "Yes" when the installer asks if it should run it. If you need to reconfigure your X server later, you can run nvidia-xconfig again from a terminal. nvidia-xconfig will make a backup copy of your configuration file before modifying it.

    Note that the X server must be restarted for any changes to its configuration file to take effect.

    More information about nvidia-xconfig can be found in the nvidia-xconfig manual page by running.

    % man nvidia-xconfig

    Manually Editing the Configuration File

    In April 2004 the X.Org Foundation released an X server based on the XFree86 server. While your release may use the X.Org X server, rather than XFree86, the differences between the two should have no impact on NVIDIA Linux users with two exceptions:

    *

    The X.Org configuration file is /etc/X11/xorg.conf while the XFree86 configuration file is /etc/X11/XF86Config. The files use the same syntax. This document refers to both files as “the X config file”.
    *

    The X.Org log file is /var/log/Xorg.#.log while the XFree86 log file is /var/log/XFree86.#.log (where # is the server number -- usually 0). The format of the log files is nearly identical. This document refers to both files as “the X log file”.

    In order for any changes to be read into the X server, you must edit the file used by the server. While it is not unreasonable to simply edit both files, it is easy to determine the correct file by searching for the line

    (==) Using config file:

    in the X log file. This line indicates the name of the X config file in use.

    If you do not have a working X config file, there are a few different ways to obtain one. A sample config file is included both with the XFree86 distribution and with the NVIDIA driver package (at /usr/share/doc/NVIDIA_GLX-1.0/). The nvidia-xconfig utility, provided with the NVIDIA driver package, can generate a new X configuration file. Additional information on the X config syntax can be found in the XF86Config manual page (man XF86Config or man xorg.conf).

    If you have a working X config file for a different driver (such as the “nv” or “vesa” driver), then simply edit the file as follows.

    Remove the line:

    Driver "nv"
    (or Driver "vesa")
    (or Driver "fbdev")

    and replace it with the line:

    Driver "nvidia"

    Remove the following lines:

    Load "dri"
    Load "GLCore"

    In the Module section of the file, add the line (if it does not already exist):

    Load "glx"

    If the X config file does not have a Module section, you can safely skip the last step if the X server installed on your system is an X.Org X server or an XFree86 X release version 4.4.0 or greater. If you are using an older XFree86 X server, add the following to your X config file:

    Section "Module"
    Load "extmod"
    Load "dbe"
    Load "type1"
    Load "freetype"
    Load "glx"
    EndSection

    There are numerous options that may be added to the X config file to tune the NVIDIA X driver. See Appendix B, X Config Options for a complete list of these options.

    Once you have completed these edits to the X config file, you may restart X and begin using the accelerated OpenGL libraries. After restarting X, any OpenGL application should automatically use the new NVIDIA libraries. (NOTE: If you encounter any problems, see Chapter 8, Common Problems for common problem diagnoses.)

    and go there from there...and, you will soon the answer to your
    question: "How do you boot with nomodeset option?" under the heading
    named "The 1st thing to try" and you probably also find your way to a
    smile..

    STOP Trying if nomodeset gives you a good boot (QUIT that page) then
    just go on smiling, or to install the nvidia driver, follow
    instructions here:
    http://forums.opensuse.org/informati...ide-users.html

    btw: /etc/X11/xorg.conf is (ideally) no longer required....and, the
    SUSE thing that used to do the graphics set was called SAX2 and both
    of those have been put out to pasture in favor of "automatic
    configuration"....if you are lucky (many are) you won't need a
    xorg.conf once you have installed the nvida driver, or maybe the open
    driver does all you need!

    Having fought a running battle with an Nvidia 6100 chipset, I would also
    suggest you add "irqpolling" to the grub boot parameters. That was the
    trick that got past a problem reading the monitor info during boot and
    allowed the system to make an intelligent determination of the monitor
    capabilities. That made the rest of the process a lot simpler.

    I use "nomodeset irqpolling" on the boot for installation which winds up
    adding those parameters to the installed grub as well but you don't want the
    irqpolling parameter once you get the Nvidia driver installed so you may
    want to remove it using the Yast grub editor. It does slow down the system a
    bit.

    Thanks for the help nomodeset worked
