Description of problem: I can't use freeglut I get this error "freeglut (./main): OpenGL GLX extension not supported by display ':0'" and I have read it's because software isn't correctly installed. Version-Release number of selected component (if applicable): Fedora 20 OS version: Linux 3.11.9-300.fc20.i686 KDE SC version: 4.11.3 How reproducible: Compile this program (http://lazyfoo.net/tutorials/OpenGL/01_hello_opengl/01_hello_freeglut.zip) with this command (g++ LUtil.cpp main.cpp -Wall -lGL -lGLU -lglut -o main) using freeglut and try to run it. Steps to Reproduce: 1. Compile program (http://lazyfoo.net/tutorials/OpenGL/01_hello_opengl/01_hello_freeglut.zip) with this command (g++ LUtil.cpp main.cpp -Wall -lGL -lGLU -lglut -o main). 2. And run ./main. 3. Actual results: [eallan@gx270eja OpenGL]$ ./main freeglut (./main): OpenGL GLX extension not supported by display ':0' [eallan@gx270eja OpenGL]$ Expected results: A gui program that draws a polygon. Additional info: I am using a Dell Trinitron monitor 1024x1280 I think. I have had problems before with x11 driver and video modes disappearing. Im using a Dell gx270 desktop.
please attach /var/log/Xorg.0.log and glxinfo output.
Created attachment 877082 [details] /var/log/Xorg.0.log /var/log/Xorg.0.log
I typed glxinfo and it says command not found.
you seem to be missing some packages, mesa-dri-drivers, mesa-libGL, maybe glx-utils.
should I install those?
yes, I would try that.
Ok I tried that and it still doesn't work.
can you reattach the new Xorg.0.log and glxinfo results now? you may have to re login after installing new packages.
Wow It works now do you still want the results?
