Disable auto-opening nautilus window after auto-mount
Each and every time I log in to Ubuntu 12.10 Nautilus opens and opens my two mounted hard drives in devices, one after the other, in separate Nautilus windows. This wouldn't be too much of a problem, however Nautilus seems very unstable in 12.10 and frequently hangs anyway when browsing files. So when this happens I see my Desktop for about 1-2 seconds and then before I have chance to do anything, it opens the first device in the File Manager, hangs, then the second, hangs, and then I am waiting an extra 30s before I can actually use my desktop. Fortunately I just have the two devices set to auto mount on boot.
How do I stop Ubuntu from opening these devices every login? No other version did this, from 12.04 backwards.
Thanks for the help.
