Hi,
When starting Flightgear from the 0.9.9 package prepared by Jon Stockill
the startup logo looked fine until the point where the actually strip and
plane should showup. There FG just quitted with the following error
message :
/local/FlightGear/FlightGear-0.9.9/share/FlightGear/Navaids/TACAN_freq.dat
X Error of failed request: BadLength (poly request too large or internal
Xlib length error)
Major opcode of failed request: 144 (GLX)
Minor opcode of failed request: 29 ()
Serial number of failed request: 837
Current serial number in output stream: 837
I spent 1/2 day searching and even compiled my own version from scratch
(with exactly the same problem !) before I had it solved, so thought I'd
better tell other people as well :-)
What goes wrong ?
Simply that FG must be loading the wrong libGL library ! Check with ldd
fgfs which libraries it uses. If you use the Nvidia driver but fgfs
uses /usr/X11R6/lib/libGL.so.1 instead of /usr/lib/libGL.so.1 this is
certainly the culprit.
Nvidia installs it's libGL.so for Nvidia cards in /usr/lib while the
original X11R6 is in /usr/X11R6/lib. Normally the latter is removed by
the Nvidia installer, but if you install e.g. Dropline Gnome new X
libraries are installed and one of them is libGL.
Simply remove this library in /usr/X11R6/lib or alternatively set your
librarypath to use /usr/lib BEFORE /usr/X11R6/lib and everything works
fine :
export LD_LIBRARY_PATH=/usr/lib:/opt/openal/lib
