Today I tried trisquel 7.0 on two laptops at my friends' just out of
curiosity.
It worked perfectly on an Asus with intel graphics (can't remember the model
though) ,graphics,resolution,wifi .. all smooth and flawless.
The second laptop I tried - Acer Aspire 7740 (somehow I remembered to note
the model on this one) worked also flawlessly, well - everything except the
ati mobility radeon chip - it had no 3d acceleration and max screen
resolution of 1280*800 (it should be 1600*900).
So yea, I will test it on other laptops but I really think you don't need to
spend an eye for those librem or whatever to get a freedom-friendly setup -
just check the parts of the laptop you want to buy before actually buying
it..
h-node webpage is very usefull for this purpose
