Ubuntu installation

Installing Ubuntu 6.05 LTS on my Toshiba satellite 5501.

1. Install ubuntu hoary CD

2. sudo passwd root

3. on root terminal,
vi /etc/apt/sources.lst
in repository list
replace 'hoary' as 'dapper'

4. apt-get update
apt-get dist-upgrade

5. reboot

6. Nvidia driver install
http://www.nvidia.com/object/linux_display_ia32_1.0-8762.html

still no pre-compiled driver, so latest 2.6.15-26-386 kernel source and header are needed.
apt-gat install linux-source-2.6.15-26-386 (or)
apt-gat install linux-source-2.6.15-26-686

apt-get install linux-386 (or linux 686)

apt-get install linux-headers-2.6.15-26-386 (or)
apt-get install linux-headers-2.6.15-26-686

Nvidia's "NVIDIA-Linux-x86-1.0-8762-pkg1.run" runs good and it makes new kernel module driver well.
But X does not start.

X's error message is that "Synaptics" "glx" "nvidia" driver were not found.

Have to switch back to "nv" driver for entering X.

Try to find reason for one day long!

http://doc.gwos.org/index.php/Latest_Nvidia_Dapper

with above howto, all trying was failed.

the method describe in there -
apt-get install nvidia-glx or
apt-get install nvidia-glx-legacy nvidia-xconfig nvidia-settings

seems to make a situation more screwed.

each driver was mixed and dis not erased clearly.


Have to find another way of dirty hack.

I, first uninstall all nvidia driver distributions all by manual.
and compared the path of each file in /var/cache/apt/archives/nvidia-glx_1.0.8762+2.6.15.11-3_i386.deb, /var/cache/apt/archives/nvidia-kernel-source-2.6.15.11-3uk_i386.deb, and /download/NVIDIA-Linux-x86-1.0-8762-pkg1(produced by nvidia run package).

The cause of the trouble is progra path!!!

nvidia's compile path was not compatible with ubuntu xorg path.
I don't know who should be blame for this.
may the one would follow the standard xorg schem, another does not.

so I have to copy nvidia's file in /usr/X11R6/lib to /usr/lib/xorg/.

My X looks like entering good!
But very bright appeared first and then goes back to black screen.

Looks like it has refresh rate or RAMDAC problem.

So I put section "Modes" in /etc/X11/xorg.conf with scratching internet.

Finally I can see the NVIDIA logo after 3days from installing!

This is my xorg.conf file.
Still have lot a work. (Optimize, Twinview <-- this option cause system freeze)
