and i thought the old gforce2 mx 400 on my 15 year old desktop was old needing the 96 driver
bad news
all of the current X11's are too new for the 71 nvidia.run
http://www.nvidia.com/object/linux-d...15-driver.html
you will NEVER be able to use that driver on ubuntu 14.04 xorg is just WAY TOO NEW
some older legacy support OS's might
have a look at CentOS 5.11
even for my GForce-2 i have to DOWNGRADE x11 to use the 96nvidia.run on Cent6.7
( downgraded to the version in 6.3 - xorg 1.12)
if Nouveau is not working on such a old card as yours
there is not to much else
use a OS that has a OLD ( very old) x11
if CentOS 5.11 is too new there is CentOS 4.9 - but that is a dead and unsupported OS
i am guessing that the 71 driver will need Xorg of 1.10 or OLDER (xfree 6.8)
the readme for the 71 driver mentions xfree86 6.8
CentOS 5.11 uses xorg 1.11
CentOS 4.9 used the old xfree86 6.8 xorg
now the 71 driver was last updated in 2011 so it ? Might? use the xorg 1.11
