Re: New install and problems with Calender
Lightning is an add-on to Thunderbird. Have you installed Lubuntu over Ubuntu or did you install it side by side with Lubuntu? Oh yes, one other option, did you install the LXDE inside of Ubuntu?
An installation of Thunderbird will require you to install the add-on. I am assuming that you did that. It is not like the stand alone Sunbird which I do not believe is supported any longer.
