[Solved] How to downgrade nvidia driver ?

I have nv5500 and I need to use nvidia173 driver, how do I install it in live dvd ? I have xfce.
I can not run x server.
Is there other way to install system and after that to install nvidia173 driver ?

Unfortunately with the release of 11.3 old nvidia card will not work correctly.

There are two ways, first - download the latest build Stage. More information about innovations that came with the distribution after the last release was written here. Of your choice will not only proprietary driver, but opensource: “nouveau” and “nv”.

The second way to install the correct version of the driver nvidia-drivers from the console:

 # eix nvidia-drivers
[I] x11-drivers/nvidia-drivers
     Available versions:  96.43.19!s 173.14.28!s ~256.44-r1!s ~256.52!s ~256.53!s ~260.19.21!s [M]~260.19.26!s 260.19.29!s{tbz2} 260.19.36!s{tbz2} ~260.19.44!s [M]~270.18!s 270.41.03!s {acpi custom-cflags gtk kernel_linux multilib}                                                                                                               
     Installed versions:  270.41.03!s(22:37:42 05.05.2011)(acpi gtk kernel_linux multilib -custom-cflags)
     Homepage:            http://www.nvidia.com/
     Description:         NVIDIA X11 driver and GLX libraries

 # emerge -a =x11-drivers/nvidia-drivers-173.14.28

and restart xorg:

 # /etc/init.d/xdm restart

The driver installation you can run both on livedvd, and after installation.

Also you can mask package nvidia-drivers to avoid unwanted updates:

echo "=x11-drivers/nvidia-drivers-173.14.28" >> /etc/portage/package.mask/nvidia-drivers

I downloaded http://mirror.cnet.kz/calculate/CLDX/stages/i686/cldx-20110503-i686.iso
It does not boot including virtualbox, error message is on the picture, it says xz compression error.

Ill try download the other one iso.

Check md5sum of downloaded iso.

md5sum path_to_iso

Sum must be

e80b33ddd7002dc1bbba518730ee96b8

My external IDE cable was broken so it did not read iso correctly.
I installed system and nvidia was installed. Its a nice way how its done automatically.
I currently like calculate.
