GUI problems ever since a GPU upgrade.
 

Hey guys, I dual-booted ubuntu several months ago but threw up my arms in fustration way too soon. So I snapped out of my weak trance and decided to work hard at understanding it... but there is a good problem.
A month ago, I upgraded my ATI 9600 SE to a Nvidia 6600 GT. I updated the drivers and everything for windows, but never did for Ubuntu. Now when I try and load my Linux OS... they say it says that my graphics card isn't supported and they must disable my "server X". I can log in and use everything, but there is no GUI, so I have no idea what to do or how to fix it.
If anyone can help, much appreaciate it.

Get the driver and install it: http://www.nvidia.com/object/unix.html
Edit the /etc/X11/xorg.conf (or XF86config). You can also use nvidia-xconfig.
Maybe you'll have to uninstall ATI drivers if they were installed.

You have plenty of threads in this site explaining how to install a NVIDIA gpu.

My problem is I only have access to a command line and that is all. I have no idea how to use one... which I guess makes things a little more harder for me :).

Ok, this is a good thing. Download the driver and compile it with:
sh NVIDIA-xxxxx.run
then edit the /etc/X11/xorg.conf with emacs:
emacs /etc/X11/xorg.conf
and change the driver to nvidia:

Section "Device"
Identifier "** ATI Radeon (generic) [radeon]"
Driver "nvidia"

save and quit with ctrl-x ctrl-s and ctrl-x ctrl-c

Launch startx or reboot.

...
Umm... How do I download it with only a command line?
Also, maybe its just the x server? Maybe something is just up with the GUI.

Just check your xorg.conf and see which driver is loaded. vesa, fglrx, nv, nvidia?

As for downloading it via CLI, try links2, lynx or another textonly browser, you may get lucky and have one installed you had no idea was there. Otherwise you will ahve to use a command like wget "ftp location" after finding the exact download location on an ftp.

I don't know very much about that particular card, but you may be able to get to a gui (not one loaded with 3D acceleration).

Try sudo dpkg-reconfigure xserver-xorg. If you can't find a driver that works, try using VESA.

Alright, so I put in sudo dpkg-reconfigure xserver-xorgand everything is going good until I have to choose my monitors color.
24 bit, I choose it, and then on the bottom it says something similiar to "warning:overwriting etc etc" and then the commandline follows. What am I suppose to type in the commandline now?

Try startx and see if it goes...

Alright, tried that. Then a whole heck load of stuff happens and then I get
fatal server error: no screens found
fatal IO error 104 on X server ":0.0" after 0 requests (0 known processed} with 0 events remaining.

Would it just be easier to instal 1.10 over 1.04?

What kernel are you using? uname -r and what is /etc/apt/sources.list?

I did a quick google and it seems that there might be a package you can download that will install the proper drivers.

If you're using 5.04 Hoary Hedgehog, try following this guide (you may need to reboot): http://ubuntuguide.org/#installnvidiadriver

My kernel is 2.6.10-5-386
Access denied when trying to do the /etc/apt/sources.list

You should just be able to more /etc/apt/sources.list
