Once more: OpenGL Problem

[ChilliConCarne]

Hello,
I'm running Slackware 11 on a AMD Athlon 1800+, Nvidia GeForceTi4200 System. I've installed the latest Nvidia drivers. Glxgears is working and DRI is enabled.

When i start tremulous i get the following:

Especially look at:

QGL_Init: Can't load libGL.so.1 from /etc/ld.so.conf or current dir:

The Content of my /etc/lib.so.1 is:

Code Select Expand


/usr/local/lib
/usr/X11R6/lib
/usr/i486-slackware-linux/lib
/opt/kde/lib


But i haven't a libGL.so.1 file in these folders.
So i searched a "libGL"-like file and set an symbolic link in my /usr/local/lib folder, because it seems that in /usr/lib is the file tremulous needs:

Code Select Expand


lrwxrwxrwx 1 root root 26 2007-02-01 17:13 libGL.so.1 -> /usr/lib/libGL.so.1.0.7184


But i still get the same error.


Does someone know what i'm doing wrong?

[tomek-k]

hmm... weird.
The libGL.so.* should be placed in /usr/lib and it should work w/o any other symlinks.

Besides NVIDIA OpenGL drivers do not use DRI.

At first upgrade your gfx drivers - you seem to have the 1.0-7184 version. The newest is 1.0-9746.

hmmm
did I misunderstand glxinfo?

direct rendering: Yes

That may be, but he means that you do not have to include a DRI section in your xorg.conf, nor do you have to enable it with a "Load DRI" line.

Yeah - DRI stands for "Direct Rendering Infrastructure". 'Direct rendering' is a more general term

Hello,
Thx for reply.
Of course, i disabled the default DRI Module in my xorg.conf:

The libGL.so.* is in my /usr/lib/ folder:

~: ls -l /usr/lib/libG*

The confusing is, that the error message doesn't say what kind of error happend. I only get:

Code Select Expand


QGL_Init: Can't load libGL.so.1 from /etc/ld.so.conf or current dir:
failed


EDIT:
Now i've installed the latest driver for my System:
NVIDIA-Linux-x86-1.0-9631-pkg1.run

The 97xx drivers doesn't support my GPU anymore.
I've added by the way in my ld.so.conf the /usr/lib folder and reloaded it as root  with ldconfig.

But i still get the same error .


BTW: I use Kernel 2.4.xx

[Caveman]

first insert into extension-section

Code Select Expand


Option         "XFree86-VidModeExtension" "enable"
then please check if X does have any 3d support endabled with glxinfo and glxgears.

then try this in the screen-section

Code Select Expand


   Option         "NvAGP" "2"                                                                                                                                                      
   Option         "RenderAccel" "false"                                                                                                                                            

and check again.

edit:

Or it just might be that you placed

Code Select Expand


          SubSection "extmod"
             Option  "omit XFree86-DGA"
          EndSubSection


into your conf, disabling all direct graphic access .)

hmm.. I can remember that there was some solution on the forum for problems with finding gl libs by trem (I had such problem with my old gfx card).
It was exporting the library path before running trem.

Some solutions:

in console run:
export LD_PRELOAD=/usr/lib/libGL.so.1
and then run tremulous

or:

Make a symbolic link for /usr/lib/libGL.so to /usr/local/games/tremulous/libGL.so.1

[tomek-k]

Wait a moment!

Have you installed trem in your home directory?

Maby this is the problem (but I'm just guessing)...

[David]

You can install it anywhere, it makes no difference.

[ChilliConCarne]

in console run:
export LD_PRELOAD=/usr/lib/libGL.so.1
and then run tremulous

THAT was the solution   !!!
THX!!!

Thx for help to all  :wink: .
