Note that I am using MinLinux. I'M trying to launch Team Fortress 2 from Valve's Steam and I'M getting the following error.

Required OpenGL extension "GL_texture_compression_s3tc" is not supported. Please install S3TC texture support.

I checked my Synaptic Package Manager and I already have the following two packages installed when I enter s3tc into the text field of the SPM.


The only one listed as not installed was libtxc-dxtn-s2tc-dev

Any ideas? Thanks.

It may be a S3TC version issue, but you should install the dev package as well, especially if you built Steam from source.
