Hello again,
Thank you for all your help I will try that as soon as possible :D I've been
testing other Ubuntu 12.04 based distributions to see if the problem was here
as well (like Elementary OS that I've found to be a gorgeous distribution to
be honest but I will talk about this in a different post for different
reasons), and I've noticed that none of this applied to those
distributions.... only for Trisquel !
I will try to see the scripts code and the version of the pm-utils software
in order to see what changes. But I've noticed one thing tho : This problem
isn't there in KDE with Trisquel (haven't tested with others), and better
than that, if I boot with the "nomodeset" option in the Kernel then I don't
have this problem at all on any DE in Trisquel.
So it is possible to be a Nouveau related problem, but until then I will have
to solve this by trying your tweaks. (I also need to understand why the HDMI
is detected - since it detects the screen connected to it - but not usable,
since no image appears on the screen).
