Description:
Trisquel 6.0
Test environment:
  • Trisquel 6.0
  • Linux-libre kernel 3.2.0-49-generic, 3.10.5-gnu
  • xserver 1.11.4
  • mesa 9.1.6
  • radeon 7.1.0
  • vesa 2.3.2
  • No proprietary firmware used.
Test result:

Radeon driver would not work without the proprietary firmwares from normal Linux kernel. Ubuntu 13.04 worked out-of-the-box, while free distributions like Trisquel automatically fallback to VESA driver. As a result, everything 2D sort of worked but at a very slow pace. Screen resolution could not be correctly detected, limited to 4:3 ratio ones only. 3D acceleration did not work.
