I discovered this evening much to my dismay that the year and a half old western digital hard drive in my main laptop is dieing. All three of the Linux installs on the system failed in various ways (typically a sign of a hardware issue) so I grabbed the closest live CD and popped it in.
There was a few gigs of data on the drive I didn't have backed up, so I opened nautilus and navigated to my files.
Ahh right - the permissions of the hard drive made it so I could not read certain folders I needed access to. Not a problem, I'll just launch the file manager as root. I opened a terminal, typed in su followed by nautilus and was greet by a crash message.
Ahh right - nautilus doesn't like to be opened as super user if I recall correctly. It had been awhile since I had used a non-sudo distro, so I hopped into #fedora on freenode to ask how I could go about launching the file manager as super user.
