From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Never use sudo for graphical apps. If you need admin permissions use pkexec instead. ie.
pkexec gparted
That's one I haven't heard before. Care to elaborate? And who works you use sudo on graphical apps in the first place?
Some GUI apps need admin permissions and will not work without them. Gparted is an example. pkexec (polkit exec) is the right way to start these apps, read this for more info https://askubuntu.com/questions/270006/why-should-users-never-use-normal-sudo-to-start-graphical-applications
After a quick Google, I learned that gksu is no more, ah well!
