Hello.

Distribution Slackware 14.1, there was a problem with support for 3D-accelerated Intel graphics card.

00:02.0 VGA compatible controller: Intel Corporation ValleyView Gen7 (rev 0e) # glxinfo | grep 'renderer string' OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 3.3, 128 bits) 

Kernel 3.8.13 MESA Version 11.2.2

At the same time, if you install Slackware-current with core 4.4, 3D acceleration works.

But you need to enable it on the kernel 3.8.
