I just had to redo my laptop and choose Ubuntu 12.10 (had 12.04 before). Now I encounter a problem with Lightning, the calendar app for Thunderbird.

My Thunderbird is of version 16.0.2 and I installed Lightning right from the add-ons site inside TB it is of version 1.8 . Anyway I cannot do anything in Lightning. I cannot open the Properties of a calender, it actually won't even properly show the calendar grid at all. Not even the default calendar "Private" works.

Any help is greatly appreciated!

Thank you.

Thunderbird and Lightning are not products of Ubuntu. They have had issues mating different distributions of TB and Lightning in the past. TB is a Mozilla product. Lightning is a third party dev product. AFAIK TB 16.0.0 and Lightning 1.8 work. So, downgrade your TB and live with it. NOT A UBUNTU ISSUE. – Ringtail Nov 13 '12 at 21:30
We update lightning when we update Thunderbird in Ubuntu. – micahg Nov 14 '12 at 2:09

Install the xul-ext-lightning package. The version from won't work with amd64 systems.
