I did a fresh install yesterday, and I got a problem on installing the latest Dropbox. The error was like this,
The program dropbox received an X Window System error.
To get it working, I did the following
Install Dropbox’s nautilus and daemon package
Download latest build of Dropbox (as of April 28, 2009), here
Issued the following command on the terminal
rm -r .dropbox-dist/
tar -xzf dropbox-lnx.x86-0.6.510.tar.gz
Restart nautilus (I did a logout)
and voila, Dropbox is now working!
Credit goes to Adam Michael Roach, I modified it to fit the current versions and releases.
