I use an Lenovo Thinkpad X60S with Ubuntu 6.10 extensively while travelling. The following are some tips that have worked for me when using Ubuntu / Thunderbird on the road:
- Sync on Arrival plug-in - I regularly just grab the laptop and leave home or the office. Sync-on-Arrival synchonises every email as it arrives, no need to close down properly OR click 'sychronise-now'. Link
- Nostalgy - I used to use Quickfile but wanted an extension that could either learn or have filters set. The solution to this problem is Nostalgy by Alain Frisch. This outstanding extension makes filing email x10 faster.
- Start off-line / on-line - I find that Thunderbird can stutter on starting when I am offline. I force the work online / offline dialog to come up on every login. (This is set under Account Preference / Off-line & Disc settings)
- Network Manager - Network manager works excellently on my machine showing all available networks, strength and security setting. My only gripe is that on car journeys the application seems to accumulate new networks endlessly and not realise it has lost some.
