graphics driver problem

[neonic]

Hello, I'm using ubuntu 10.04 and I have a problem running 3D applications. With any openGL application I try to run, I get this message:

Xlib:  extension "GLX" missing on display ":0.0".
freeglut (./simpleGL.exe): OpenGL GLX extension not supported by display ':0.0'

When I do glxinfo, I get:

name of display: :0.0

Xlib:  extension "GLX" missing on display ":0.0".
Xlib:  extension "GLX" missing on display ":0.0".

My graphics card is an ATI X1600 Pro, I had it working for a while. The problem started when apt-get remove unexpectedly started removing programs recursively. To restore these programs I copied all the installed software from an NVIDEA pc. I got ubuntu running again, but no 3d graphics.
I noticed that under "System>Administration" there's an option named "NVIDEA Xserver settings". So I believe the NVIDEA driver is still hidden somewhere and I don't know how to show it or get rid of it.

I have shown this problem at ubuntuforums, but I got no reaction. So now I'm showing it here. Does anyone know any steps that I could take to find the source of my problem and/or get rid of it?

Thanks!

try

sudo apt-get remove --purge nvidia
sudo apt-get clean

then

sudo apt-get install nvidia-current

[neonic]

try

sudo apt-get remove --purge nvidia

I tried "sudo apt-get remove --purge nvidia*", it removed several programs. After rebooting, I can now start openGL programs again.
This is an improvement! Thanks!

The graphics are just very slow, however.
glxinfo now gives the following output:

name of display: :0.0
Segmentation fault

I believe, my ubuntu runs the opensource ATI driver now. Before the graphics problem this driver gave fast graphics, so I guess my ubuntu isn't fully repaired yet.

Does someone know how to solve this problem as well?

Thanks!

Which Graphics Card do you have? ATI or Nvidia? xorg.conf is listing ATI Card and you have installed Nvidia Driver.

Post the output of this

lspci | grep -i vga
grep -i driver /etc/X11/xorg.conf

My graphics card is an ATI X1600 Pro. Sorry for the confusion, but I removed all nvidia software from my ubuntu since the previous reply.

Post the output of this

lspci | grep -i vga
grep -i driver /etc/X11/xorg.conf

"lspci | grep -i vga" gives:

01:00.0 VGA compatible controller: ATI Technologies Inc RV530 [Radeon X1600]

"grep -i driver /etc/X11/xorg.conf" gives:

grep: /etc/X11/xorg.conf: No such file or directory

Whuh! It's no longer there?

Guess it went away when I removed the nvidia software.
Do I actually need "/etc/X11/xorg.conf" ?

[devils casper]

Theoretically, we do not need xorg.conf file now because X Server detect and configure Graphics card and display itself. Practically, we have to generate xorg.conf file in a few machines to configure Display correctly.

Doesn't Hardware Drivers option in Administrative Menu detect ATI Card and suggest it's driver installation?

Doesn't Hardware Drivers option in Administrative Menu detect ATI Card and suggest it's driver installation?

It just shows an empty list and the only message is: No proprietary Drivers are in use on this System

[devils casper]

According to this list, your Graphics Card is well supported and Ubuntu should detect and install ATI Driver itself. Have enabled additional drivers?
Go to the Additional Drivers Manager (System -> Administration -> Additional Drivers) and activate the "ATI/AMD proprietary FGLRX graphics driver". Ubuntu will then install and configure the driver for you.

I'm sorry! My System -> Administration tab has no entry named "Additional Drivers". Also, in the past, my ubuntu ran with open source driver and the results were fine.
Plus, I've already tried using the fglrx driver to solve my problem, but that only made things worse. (after installing fglrx, the openGL applications didn't run at all)
