Fix for can’t start graphical apps as admin.

Earlier today I would get an error about not being able to read the users Xsession file or something when I tried to start any Administrator program from the menu. sudo worked fine, but gksudo (the graphical password entry thing) didn’t.

Solution: full root partition.

Tips to free up space:

1. Restart. This clears /tmp
2. sudo apt-get autoremove && sudo apt-get clean (remove cached and unnecessary packages)
3. check /var/tmp
4. Maybe uninstall a hefty program or two. Games take up a *lot* of space.
5. Don’t be like me and make a 10gb / partition on a terabyte hard drive [facehand].

Simple!
