|Ah~ freshly minted Ubuntu 14.04 LTS.|
Things went nice and smooth with the upgrade. My files didn't get chewed and spit on, my wallpaper's still intact, and the system seems to run much more smoothly than 13.10. This is a pretty awesome release so far.
Performance-wise, 14.04 is way better than 13.10. I've been using the open source drivers since my last clean install of 13.10 and I can tell you there's moments when I know I'm not getting everything out of that HD7750. The Ubuntu Dash isn't completely smooth, and the most obvious is when you launch LibreOffice Calc and have to wait a minute or two while the UI is not responding. Now, even Calc is ready to go the moment the UI is visible.
Personal files and settings remained intact, as I mentioned earlier. Your music library is still the same, Thunderbird feeds and Firefox bookmarks are still where they're supposed to be. Basically, backup before starting the upgrade (just in case) but no need to panic if you realised you've forgotten to back something up.
Some obvious changes
|New Rhythmbox UI. Looks a bit less cluttered.|
There's a new lock screen that fades smoothly into your desktop. I like that a lot.
|Turn on integrated menus in the Appearance Behaviour tab.|
Software installed from 3rd party repositories are obviously gone (Handbrake, for example). It'll take a while for them to catch up.
Everything looks like it's running as they're supposed to. I wasn't paying attention but I think it took less than half an hour to upgrade the system? That's just awesome! This may be the smoothest and fastest upgrade I've experienced (Windows included). While Ubuntu's had smooth upgrades before, it's never been this quick mainly since I've been using Update Manager/Software Updater which required downloading gigabytes worth of packages as part of the process.
Upgrade to Ubuntu 14.04 now I you haven't already.
