There is a problem with some ATI graphics hardware using ATI's proprietary
fglrx driver in Linux. FlightGear runs at about 25% of expected frame rate,
eventually spewing lots of these:
fglX11AllocateManagedSurface: __FGLTexMgrAllocMem failed!!
The problem occurs in FG 0.9.9 and later CVS versions. Many many many
thanks if you can point to a fix or workaround.
I have a desktop and a laptop, both are dual-boot Windows XP and Linux, and
both have ATI Radeon hardware. FlightGear runs well in three of the four
environments: Windows or Linux on the desktop box, and Windows on the
laptop. The problem occurs only on the laptop under Linux.
Possibly another reference to this same problem with the ATI hardware
and/or driver can be found at
http://www.rage3d.com/board/showthread.php?t=33819385 ,
which implies that this ATI bug can be worked around.
Running fgfs with more verbose debug levels produces immense amounts of
output, but I don't see anything relevant to include here. I'll
certainly make
that data available if it would help.
Changing Linux distributions didn't matter. Rebuilding the kernels with
different options didn't help. Neither did changing interesting fglrx
parameters in xorg.conf. Running agpgart internally in fglrx or as a kernel
module didn't change anything. Running fgfs with various color depths,
resolutions, and disabling textures, etc. didn't change the error symptoms.
Other 3d-accelerated apps work fine.
Details of the environment that fails:
Dell Inspiron 6000 with 1GB RAM
ATI graphics hardware (M22 5460) (Radeon X300)
Linux (I tried Fedora Core 4 w/2.6.14 kernel, and Ubuntu 5.10 with
2.6.12 kernel)
ATI Proprietary fglrx driver (tried 8.16.20 with Ubuntu and 8.23.7 with
Fedora)
Xorg 6.8.2
fgl_glxgears runs at about 215 fps, glxgears a tad over 1000.
