I personally think that LXDE is better looking than XFCE, but in comparing
Trisquel's default look for Mini, it looks ok. The Linux Mint team really
stepped up their game with their LXDE version looks wise with 10 and 11 and
the Trisquel team should look at that for reference. I've tried other LXDE
based distros and it seems to be the best looking out of the box.
Speaking of Linux Mint, I heard that 12 (based off of 11.10) will come out in
two versions: full Gnome Shell desktop and a backported Gnome 2.32 into the
Ubuntu 11.10 codebase coexisting with Gnome 3 libraries. The second option
seems to be a lot of work, but their team is pretty solid for stable
releases.
If Linux Mint is able to have Gnome 2 and Gnome 3 libraries co exist, would
the Trisquel team be interested in taking their code and migrating it into
Trisquel 5.5 ?
