[Dri-users] XFree86.log says direct rendering was enabled, glxinfo disagrees

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

I've just installed an original Radeon QD 32MB DDR, built XFree86
4.2 from CVS, built the mesa-4-0-branch of the DRI CVS tree, and
installed them both, along with kernel 2.4.18-pre9. X starts up
nicely (and quickly) and opengl apps run successfully, but without
hardware acceleration.=20

XFree86.log shows an apparently normal DRM/DRI initialisation, with
no errors at all listed, and ending by saying direct rendering is=20
enabled:

glxinfo has a different opinion:
name of display: :0.0
display: :0  screen: 0
direct rendering: No
server glx vendor string: SGI
server glx version string: 1.2
server glx extensions:
    GLX_EXT_visual_info, GLX_EXT_visual_rating,
    GLX_EXT_import_context
client glx vendor string: SGI

    GLX_EXT_import_context
    GLX extensions:

    GLX_EXT_import_context
OpenGL vendor string: Mesa project: www.mesa3d.org
OpenGL renderer string: Mesa GLX Indirect
OpenGL version string: 1.3 Mesa 4.0.1

As far as I can tell all the libraries are the right ones - libGL.so
is the one installed by the DRI build, as is libOSMesa.so, and the
symlinks point to the right places. ldd indicates that the right
files are being loaded. xdpyinfo lists the GLX, SGI-GLX and
XFree86-DRI extensions.

I've been running DRI successfully for the last six months or so
with a g400, without any such problems - it's only with the Radeon
that these problems come up.

Thanks for any help,
Simon Fowler
