Run Thunderbird in the Tray at Startup (on Linux using All Tray)
For some reason, I wanted Thunderbird to run at startup, and to run in the tray. Email is just one of those programs I like to have running all the time, but I don’t want it cluttering up the taskbar. I wasn’t able to find an addon to make Thunderbird run in the tray the way I wanted, but after some searching I found AllTray which solves the problem perfectly.
1. Install Alltray from their website or you can “sudo apt-get install alltray” from the console
2. Create the following bash script:
#!/bin/sh
alltray -na thunderbird
3. Add the script to your list of start up programs. In Ubuntu/Gnome: click System > Preferences > Sessions and add your script to the list of startup items.
Alltray is a great program and can be used to put any program in to your tray. There are other ways to put Thunderbird in to your tray, but this way works the best for me.

Great work.
[...] Grab the sensors-applet from synaptic. NB log out and re-log in to be able to add it to the top panel. Edit Main Menu preferences. Increase height of top panel until icons jump one step in size. Set screen saver. See earlier post on PHP and Apache ( Apache and PHP on Ubuntu - Very Easy Installation ). NB install mysql module for php from synaptic - php5-mysql and this includes both mysql and mysqli. From the virtual XP MySQL, do a data dump ready to import into MySQL in Ubuntu. Set up cron jobs. From synaptic install gnome schedule, then find it under Applications > System Tools > Scheduled jobs.
