OpenGL
From ArchWiki
OpenGL was not working out of the box for me, here is what I did:
make sure your card can handle openGL
put "dri" and "glx" are in your xorg.conf file:
Section "Module" Load "glx" Load "dri" Load "i810" Load "ddc" # ddc probing of monitor Load "dbe" Load "extmod" Load "bitmap" # bitmap-fonts Load "type1" Load "freetype" Load "record"
It should now work, if it does not, make sure you have the libraries installed. I had to install the package "libgl-dri".
