• Trisquel 6.0
• Linux-libre kernel 3.2.0-49-generic, 3.10.5-gnu
• xserver 1.11.4
• mesa 9.1.6
• nouveau 1.0.9
• No proprietary firmware used.

The following test result was collected in August 2013. Trisquel 6.0 LiveCD would not login to its live desktop environment. Use netinstall instead in order to install the system. Even with the up-to-date kernel and drivers from the official repository, the login screen would not appear after the installation. Just a black screen. It seems the system would not switch to VESA driver automatically. Use another display card (Intel/AMD) to install a newer kernel (3.10.5-gnu) and nouveau driver (1.0.9) in order to make it work. Compiz and OPENGL does not work with mesa 9.2-devel and 9.3-devel, fallback to metacity window manager to display the title bar.
