I upgraded (in place, via Ubuntu Software Update) from Ubuntu 13.10 with no problem, and only one minor utility did not work which is no problem (it is unsupported software).
My new laptop (which came with Ubuntu 13.10) is 64bit which means Ubuntu 14.04 is 64bit version.
Some features seen on desktop:
- The orange Ubuntu icon on the top-right Title Bar is the treed Classic Menu add-on (I hate using search to find applications)
- Note, you can get Steam for Ubuntu
- The blue icon with the arrow in the Unity Bar (left side of desktop) is Krusader split-panel file manager, which has an option to run in Root Mode (Root is the equivalent of Windows Administrator mode)
- As you can see Ubuntu comes with Firefox WEB browser
- And my favorite Desktop Calendar "Rainlendar Lite" (free version) which I also have on my WinXP Desktop rig
Rainlendar is NOT included in the Ubuntu Software Center but can be downloaded from their site.
Rainlendar Home - Rainlendar all version download
The install package is a .deb file, I used the 64bit Debian/Ubuntu version.
WARNING: Do NOT use Ubuntu Software Center to install! (which is the default installer)
Use the GDeb Package Installer, which comes with Ubuntu 14. Recommend this installer for any Linux Debian software NOT found on Ubuntu Software Center or Synaptic Package Manager.
