FlightGear : OpenGL GLX error

[dysharmonic]

Hi

I stumbled upon this game quite a few weeks ago, but never gave it a try. Installed it and ran it and got this error:

GLUT: Fatal Error in fgfs: OpenGL GLX extension not supported by display: :0

Here's my /etc/X11/XF86Config-4

Section "Module"

# This loads the DBE extension module.
Load "dbe"

# This loads the Video for Linux module.

You need a Load "glx" line in your XF86Config-4 file too. In the modules section.

[dysharmonic]

Thanx a lot!

It works!

So now how do I fly this thing? Also, I dont have any sound?

Thanx.

[bwkaz]

I have no idea how to fly, I've never played flightgear... ;)

As for sound, ... umm... does it log any messages to the terminal you start it from? If you're starting it from a shortcut, open a terminal and run it from there instead.

[dysharmonic]

These are the only lines I could find which have the words sound/snd/audio in them.

WARNING: slScheduler: Needs a sound card that supports 8 bits per sample.
Audio initialization failed!
WARNING: slSample: loadWavFile: Cannot open '/usr/lib/FlightGear/Sounds/click.wav' for reading.

Sound is working fine in other apps/games.

But not all games have sound tho.

Hmm..there are posts here on FG, sadly w/o much resolving tho...

[bwkaz]

Sounds like your card is in 16-bit "mode", and for some reason, FG won't work with that...

Do you know which library FG uses for playing sounds? SDL maybe? OpenAL?

Which card do you have, and which drivers are you using (alsa, oss, either of those+esd, either of those+arts)?

[dysharmonic]

Hi

This is an nvidia nforce sound card but I didnt install the drivers from nvidia, just these 3 modules, during sndconfig.

I'm not sure which lib or which driver (esd, arts, alsa) is used but xmms works fine w/ esd selescted.

Another thing is fgfs is excruciatingly slow after just a few seconds, i.e. after pressing the a key (acceleration i think).

I'm on a Duron 1.05G, 32Mb of GForce 2 MX, and 352Mb of DDR266 w/ lots of free space on /.

(The help file for fgfs is at /usr/lib/FlightGear/Docs/index.html)

I'm d/loading the latest version of that game and maybe they have a Windows version too :)

Thanx.

[dysharmonic]

Well, doesnt seem like they have an rpm package for Mdk...just some source code for compilation....
