[PLUG] How to run fsck on /home partition

[Richard C. Steffens]

I just installed Google Earth on my Ubuntu machine. When the install 
script finished I let it start the program. I "visited" a bunch of 
places, setting place marks as I went. Eventually it froze. I was unable 
to shut down the program, and as I switched to other running programs, 
they froze. Eventually the system no longer responded to mouse and 
keyboard actions and I had to power cycle the machine to get it running 
again. When I did, I got a message telling me to run fsck on /dev/sda3. 
That's /home on my system. fsck warned against running it on a mounted fs.

Do I need to stop X and run from the terminal?

When I tried to umount /home I was told it couldn't be done. I was only 
running a terminal window at the time, but now that I think about it, I 
assume there are some hidden files related to X, or maybe something 
else, that have to be closed.
