I have only even run Flightgear on NVidia cards. There are packages available on Ubuntu but I haven't tried them on the PC with an Intel graphics card to see if they will work.
root@sdrbox1:/usr/src/ghpsdr3-alex# apt-cache search flightgear
fgfs-base - Flight Gear Flight Simulator -- base files
fgo - simple graphical launcher for FlightGear
fgrun - graphical frontend for running FlightGear
flightgear - Flight Gear Flight Simulator
simgear-dev - Simulator Construction Gear -- development files
simgear2.4.0 - Simulator Construction Gear -- shared libraries

This is what I suggested to Donn.
Mesa-libGLESv2-2
Description :
OpenGL|ES is a cross-platform API for full-function 2D and 3D
graphics on embedded systems - including consoles, phones, appliances
and vehicles. It contains a subset of OpenGL plus a number of
extensions for the special needs of embedded systems.

May be as it's only a subset of OpenGL it's missing something that is needed.

Regards
Sid.

Mesa OpenGL is a software implementation of OpenGL -- I doubt it will run FlightGear fast enough on any hardware to be useful, and it may not have support for all the advanced shaders we are using??? Typically you need to install the hardware accelerated drivers for your video card, even on linux. That said, I've always stuck with nvidia graphics hardware here so I don't know what is specifically required for a radeon card or what issues you might run into. Caution Arnt may troll about open-source video drivers and groklaw endlessly, but I've never heard that he got FlightGear running reasonably on purely open-source drivers. On the other hand, my experience is with nvidia so I may not be much help here either.

Curt.

    No Sir as a user.  I had a suggest from Sid Boyce and it was about a
    file.rpm which I fond and it didn't help.  Except I was going to
    recompile it as a test.  But again it will no longer compile for a
    test.
