Re: [Trisquel-users] Who of this community honestly runs Trisquel GNU/Linux?

[leestrobel]

Yeah, they do! There a nice wiki page here that provides details on how to  
install/configure Libreboot and Trisquel. Only very specific Macbook versions  
support it though (1,1 and 2,1), although you can get hold of one off of Ebay  
very easily. That's where I got mine - had to replace the battery and fan,  
but now it runs great.

I don't know about the opengl question ... not sure if the graphics chip  
supports those versions. Could probably find out on the internet somehow.
