[xubuntu-users] GeForce4 Old-video-card working wrong in Xubuntu 14.04

[Fernando Duo]

I have an old computer wich was running Xubuntu 12.04, quite good. As I
upgraded it last Saturday it started working wrong, specialy video totally
distortionated.
When I learned I can change default video configuration, puting a xorg.conf
in /etc/X11/, I tried difrent resolutions.

As I tried difrent resolutions and syncs I could see things get better when
I limitate horizontal sync to low values, giving me the chance to get up to
800x600 resolution.
I took a Xubuntu 11.10 Desktop/Live CD to learn modelines using xvidtune.
The following modelines worked all perfectly good with 11.10. Also take a
look to syncs ranges, they are within the monitor capabilities:

ubuntu at ubuntu:~/Desktop$ xvidtune
Vendor: (null), Model: (null)
Num hsync: 1, Num vsync: 1
hsync range 0:  30.00 -  95.00
vsync range 0:  50.00 - 160.00

"1280x1024"   135.00   1280 1296 1440 1688   1024 1025 1028 1066 +hsync
+vsync
"1024x768"     94.50   1024 1072 1168 1376    768  769  772  808 +hsync
+vsync
"800x600"      56.25    800  832  896 1048    600  601  604  631 +hsync
+vsync
"640x480"      36.00    640  696  752  832    480  481  484  509 -hsync
-vsync


Then I puted it in the /etc/X11/xorg.conf, without success (see the file I
send).
So I guess it's a matter of the nvidia driver. I'd like to know wich driver
uses 11.10, with my LiveCD ¿How could I know?

Grub menu showed bad behavior before Xubuntu 14.04, having heavy distortion
since Xubuntu 12.04.
Now, even console interface works wrong, it get almost no distortion but
it's like there were flying pixels.
I installed nvidia tools, and tried this:

root at fernando-machine:~# nvidia-detector
none
