Re: [Trisquel-users] Cannot activate Desktop effects

[magicbanana]

libgl1-mesa-dri-experimental is Free software. It is in Slaine's and Dagda's  
repositories (no repository to add). You can, for instance, install it very  
easily from Synaptic (in the System/Administration menu).

nVidia's driver is proprietary software. Neither Trisquel nor people on this  
forum would help you install it.
