Test conducted in August 2013. Trisquel 6.0 liveCD could not login to its desktop environment, automatically logout back to login screen. After netinstall it shows only a black screen at startup. It seems the system failed to switch to VESA driver automatically. Must use another display card (Intel/AMD) to boot the system and upgrade to a newer kernel (3.10.7-gnu) and nouveau driver 1.0.9 in order to make it work. gNewSense 3.0 LiveDVD worked but it was using VESA driver. Compiz and OPENGL did not work with mesa 9.2-devel and 9.3-devel.

Worked with the newer linux-libre kernels from the following PPAs:

• https://launchpad.net/~linux-libre/+archive/ppa/ (3.8.x-gnu)
• http://jxself.org/linux-libre/ (3.10.x-gnu)
