[Trisquel-users] Re : So is this true about AMD on Trisquel?

[magicbanana]

Radeon cards work on Trisquel. But because of the proprietary firmware you  
mentioned (and that remains proprietary until now), some features do not  
work. That includes 3D acceleration.

If your computer has an Intel graphical chipset (the case for all Intel  
processors, for many years), you had better removed the Radeon card and enjoy  
the perfect support of this chipset by the Linux-libre kernel (that all free  
GNU/Linux distributions, including Trisquel, use). You would save energy in  
this way too.
