Ubuntu 14.04 was thee most combative linux os yet, can not run shell scripts from the desktop, krusader suffered locked config files and no cure in site from the developer.
have to run as root ; plagued with security stepping on users feet all the time with add-on software. I am now trying the latest Mint 64 bit and so far so good, to early to say 5 stars but it's doing well so far. Try and add a launcher or widget in the 14.04 task or launch bar ? HA!! What a joke the right mouse button menu options are stripped bare. Terrible loss of user control. Tried different desktops no luck, made things worse.

Ubuntu 12.04 LTS blows away the 14.04 in my opinion.
