Turning on context texture Rendering

Hi there all

I have downloaded flightgear and wish to run it on my linux machine.
Specs are: AMD64 Phenom Processor, 4 Gig Ram, ATI Radeon 3450 graphics card, 22" acer monitor.

When I run flightgear in a shell, I get this:
glenn@glenn-acer:~$ fgfs
freeglut (fgfs): Unable to create direct context rendering for window 'FlightGear'
This may hurt performance.

  Description:   Cessna C-172
Segmentation fault
And when I try and diagnose the problem using glxinfo:
glenn@glenn-acer:~$ glxinfo
name of display: :0.0
display: :0  screen: 0
direct rendering: No (If you want to find out why, try setting LIBGL_DEBUG=verbose)

When I test using glsgears, I get this:
glenn@glenn-acer:~$ glxgears
4838 frames in 5.0 seconds = 965.033 FPS
5320 frames in 5.0 seconds = 1062.554 FPS
5160 frames in 5.0 seconds = 1029.839 FPS
4720 frames in 5.0 seconds = 943.431 FPS
4325 frames in 5.0 seconds = 861.546 FPS
4736 frames in 5.0 seconds = 944.438 FPS
XIO:  fatal IO error 11 (Resource temporarily unavailable) on X server ":0.0"
      after 63128 requests (49064 known processed) with 0 events remaining.
I have tried installing the restricted driver for my ATI Radeon graphics card, but along with a thick black band at the bottom of my display, Flightgear's GUI flickers on and off and on again several times a second.

Is anyone out there able to help?
