I have been running FG on Ubuntu for a long time ,up to now without many problems.
My last working version of FG is 2016.2.1 on Ubuntu 16.10.The computer it is running on has a two core processor with 8G of ram.I have also installed FG 2018.3.1 on Ubuntu18.10 on this computer and when I go to use it not long after start it crashes showing a segmentation fault(screen dumped).
I also have an 8 core machine with 8G of memory and it is running FG2018.1.1 it has the same problem as FG2018.3.1.
I run FG from the terminal as soon as I hit enter in the terminal the terminal icon appears on the launcher but also does a white box with a red circle inside it and a red slash across the circle.When I click on this it says OSGVIEWER.After the sim has crashed or froze the OSGVIEWER goes away.
I have tried changing the AI folder and the Scenery folder.I have tried changing the aircraft I am using,I use the ufo craft as I used to do a lot aircraft schedules not so many these days. As well as the seg faults i also see one that says something to the effect "memory bad failed to find shortest route.
I have looked through this thread well at least from the date I started to see this problem and there is nothing that is like the problem I am seeing.As I don't believe I am the only person in the FG world to be having this problem It's either my hardware is not powerful enough anymore,I get about 12-16 FPS around heavy scenery, or I have not been able to find the fix on the web.
My FG2016.2.1 I think I got from GETDEB before it closed.
My FG2018.1.1 I got out of the 18.04 repository
My FG2018.3.1 I got from apt get on 18.10.
Thanks for any help.
