I have a newer, touchscreen laptop/tablet (a 2-in-1? but it doesn't come apart, it folds back and becomes a tablet), and I'd like the fullest support possible for my newer device. When trying to upgrade by computer to Ubuntu Gnome 14.10 from 14.04 recently, I noticed that the release notes state that Utopic is a devolopment release, not intended for use on production machines. However, I've yet to see a way to install either gnome 3.14, or 3.16 on 14.04. However, I can update the Gnome DE to version 3.14 on Utopic. I was wondering if anyone on here could please tell me, exacly how buggy Utopic is. With a name like Utopic Unicorn, one would think that the software is fully mature. Will I likely encounter a lot of bugs? Is it worth updating past the LTS release to get support for my newer device?
14.10 Utopic has been released (in October last year) and is stable, but is newer than 14.04 LTS Trusty (which could be 'more stable') - 15.04 Vivid is in development and will be released in April. See more here
As for GNOME, Ubuntu sort of misses out on newer versions due to the timing of GNOME's release and Ubuntu's. So if you want to install a newer version (e.g. 3.14 on Utopic), you need to use PPA's to update to it:
Note this is experimental, and may break other desktop environments including Unity. Source.
(I will add that Fedora and Arch, different distributions of Linux, often have the newer versions of GNOME more easily available by default)
