I think I broke my OpenGL...


As the title says, I think I broke my Open GL.
(Please nobody ask what I was doing to break it, because I can't remember. )
Now, none of the OpenGL screen-savers work at all. And whenever I try to start an OpenGL application from command line I get the following error:
Quote:
OpenGL GLX extension not supported by display ':0.0'
It was working fine until I messed with something. (Maybe this'll teach me... but probably not.)
What I would like to know is whether or not I would have to re-install to fix this.
(It won't bother me either way)

Do you have

Load "glx"

in your modules section of /etc/X11/xorg.conf?

AFAIK, yes. But I'll go check.

EDIT: Yes, it's there.

what does the command 'glxinfo | grep GLX' show? Loads of glx stuff, or nothing?

Also which display driver are you using?

The nv driver doesn't support 3D. Did you install the Nvidia drivers? That should say nvidia if you did.

um... no, I didn't.

Could you point me in the right direction of the 'nvidia' drivers?

/me feeling like a right idiot...

EDIT: I think I've found them...

Exclamation Uh oh...

I've installed the nvidia drivers. and now I don't have X. I'm posting this using lynx. It's all gone dark!!
Funny stuff over, I'm going to re-install. Maybe it might fix some other issues I have been having.
Like the fact that my keyboard is set to the german (I think) layout, and will not change back, no matter what.

EDIT: Stuff it. I can't be bothered with a re-install. (Not today, anyway.) I found that it did backup my xorg.conf, so now I have X back up. (Posted with Firefox.)

Uh oh, again.

No kidding...

Well, let's try XMMS.

Uh huh...
I think I've broken something much more serious than just OpenGL, and anything I do is just treating the symptoms, not the cause.

I think I'll re-install in a few weeks when (if ) I get a separate HDD for my documents.

/me is procrastinating, and praying it all doesn't die on me.

How did you install the nvidia drivers? It almost sounds like it found the wrong kernel source and messed up the kernel.

I got the nvidia drivers from the nvidia site, ran the installer as root (using single user boot). It completed (with no errors which is surprising. ) it installed, and I continued the boot process.
entered runlevel 5, and it tried to start KDM. And failed.

Que sera sera.

I'm about due for a re-install anyway...

Did you change the driver from 'nv' to 'nvidia' in your /etc/X11/xorg.conf ?

You will probably also need to 'modprobe nvidia' too.

D'oh.

Ah well, never mind. I'll remember that for next time.
