yo, i just installed Unreal Tournament 2003 - demo version off a magazine (LinuxFormat). when i try running it, the splash screen appears but then i get the error:

couldn't set video mode: couldn't find matching GLX visual

Also, from the same magazine i got Flightgear-0.7.10 on DVD which (as the magazine says) can be run from the disc with a Flightgear.sh script (which will run an fgfs executable) but on running it i get the error:

Flightgear.sh: ./fgfs: permission denied

i'm using slackware 8.1. what should i do?

hehe know this one

look into your /etc/fstab
With the dvd drive the options are users,default i guess.
The trick is that default disables the execution from the mounted drive to prevent abuse.

Try adding exec before default, and it _should_ work.
If not try reading the fstab manpage and look what is set for the default entry and what is does mean.

As for GLX: is it enabled? Try running glxinfo to get more information, is direct rendering enabled?
Does glxgears work? And even if it does work try to get direct rendering to work.

Also i don't know about the demo, but the retail version does require an NVidia card to work properly (IIRC).

More precisely it needs a video card with drivers which support S3TC, the new Radeon 8500 - 9700 drivers should work, as should the Accelerated-X drivers (from xig) for the Radeon 8500.


Evil_lafta.

What graphics card do you have?
What drivers are you using?
Do other OpenGL programs work okay?
How many FPS do you get in glxgears?
What does glxinfo indicate?
What resolutions do you have setup in your XF86Config (in 'Section "Screen"')?

The first thing that UT2003 does is switch to GLX mode in 800x600, if you have not setup your X-Server to allow it to switch 800x600 you will very likely get a message like the one you have got (I can't remember the exact error message I got, but it was very similar to yours).

BTW if you post to the Linux Format Forums then I will probably see your reply sooner (post here still ofcourse, so that more people may help).
