No, sudo from a terminal works fine.
Well, I booted up the pc today and I received some sort of a GUI error in a pop-up window when after logging in... unfortunately I didn't write it down. I'm assuming it's from the GUI error, but the MintUpdate icon didn't even show up and then I noticed that none of my favorite programs were listed in the "Start Menu" (what do you call that in Mint?). Also in Firefox I couldn't use the built-in search box or back/forward buttons.
I have a feeling something's terminally screwed up. Since installing about a month ago, some of the things I've done:
-Rearranged/renumbered some of my partitions w/ gparted
-Used VirtualBox a lot (had to make changes to enable usbfs)
-I'm down to about 4GB left on my partition (using 1 partition for root & home)
I also get a lot of text messages when I shut down the OS... something about bus connection failures (the text disappears so quick).
Honestly, I'm attempting to switch from Windows because I hate having to reinstall the system for best performance, but I'm getting the feeling I'm gonna have to reinstall Mint.
That's what happens when a noob tries to be a power user... but, only one way to really learn I guess.
