I have just installed flightgear on ubuntu using the standard package management.
The system is a system76 laptop, using a second console, 24 free gig of ram.
The flightgear version is 2019.1.1
I start up flightgear by running fgfs from the console. I maximise the screen over the second console.
I am in a cessna. I set time to noon. I complete the first tutorial, checking the plane. I think I get to starting the engine, the whole thing crashes.
The shell window console error (many prior warnings) is:
-------------------------------------------------------------------------------------------------------
674.53 [ALRT]:nasal Nasal runtime error: Timer is running, cannot change type between real/sim time

Am attempting to use the saitek controllers as far as possible, they appear to partially work.
