The Unity Desktop Shell for GNOME 3 on Ubuntu Linux has created a lot of controversy in the desktop Linux world. Some users love the new forward looking vision of Unity while others long for a more traditional desktop layout. One of the criticisms of Unity has been its lack of configuration settings.

My main computer at home acts as a file and media server for the whole house, so it's pretty much turned on all the time.

My SATA optical drive would show up as /dev/sr0, however the normal symlinks to cdrom, cdrw, dvd, dvdrw were not there. I would go to the terminal and manually create the symlink and things would work fine, but after a reboot my symlinks would be gone! I found the fix in an old bug report on LaunchPad.

For now though, I'll just show the setup so you can send an email from the command line. This process has been tested on Ubuntu 12.04 and Linux Mint 13. Read more
