I am running thunderbird over an ssh -Y connection on my local LAN. The application runs with no visible (to me) problems, other than those reported in the console window. So, when it starts, it gives some GFX1/glxtest messages which I assume come from the fact that it runs remotely and some numbers reported to glxtest do not make sense (thunderbird runs on a dual GPU laptop, with the nvidia card enabled in performance mode). Then it says it cannot deduce the GPU vendor but I still get normal (if not a bit slow) GUI output. Then I get console errors mostly from the calendar, which have to do with my google account, but the most worrying one is this one: "Assert failed: Calendar manager initialised calendars before loadCalendarComponent ran on the first 3pane window. This should not happen.\n " Are they important and can I do something about it? (Screenshot attached) Thanks for your time! Nestor
