nvidia woes

[Josey]

I have been having trouble getting descent 3 to run.
I'll run the game in the same resolution as my desktop but the game will be in the middle pretty small with alot of black around it. The game claims it's still in the same resolution.
I hit new game and pick a mission. The mission loads and then crashes me back to the desktop. If I run it through terminal I get some glx errors saying nvidia isnt installed right..

So I have been trying to install nvidia correctly and through trial and error I have found that the way to get descent 3 to work perfectly is to boot into recovery mode and then use 'startx' to get into xubuntu gui.

I use the same launcher as I do in the normal boot.
I load the game that way and it works perfect.
This is one of the first games I've got loaded on here and I'm impressed. It runs better than it did in XP when I get it running. :)

Anyway... if I boot normally I'm back to a small game screen and crashes.
I'm sure the problem is in my xorg.conf but I'm pretty lost as this is my 2nd week in linux.

I haven't modified anything really after running 'sudo aptitude install nvidia-glx'

Any idea's why recovery mode would be better for nvidia-glx I guess is my question here. :)

Any help is apriciated.

Here is the error I get when the game crashes when running from terminal.

If I do this nvidia works beautifully.
I remove nvidia-glx, log out of xfrce session and restart x server.
Then I install nvidia-glx from terminal then startx everything is perfect.
It runs like a gem if I don't have nvidia-glx running on a normal boot. I just don't get it. What changes?

After some digging it seem i might have something else thats running using opengl or oss and theres a conflict. :-k

Anyone have any ideas for me? :confused:

It seems my problem was xserver-xgl. Running this and gaming seems to be a bad idea.

Also had to fix /ect/gdm/gdm.conf-custom and remove xgl options so I could get something other than terminal at boot up. In the future it might be a good idea to have packages like xserver-xgl edit the xgl options out of gdm.conf-custom so it doesn't break the boot manager when removed.

For anyone else that might be reverting back from xserver-xgl and are having trouble loading gdm...

sudo gedit /ect/gdm/gdm.conf-custom
delete this under [servers]
