xorg log

take the Load "GLcore" line out of your xorg.conf and try again.

Still it fails:

(II) Loading /opt/xorg/lib/modules/extensions/libglx.so
dlopen: /opt/xorg/lib/modules/extensions/libglx.so: undefined symbol: glSamplePa
tternSGIS
(EE) Failed to load /opt/xorg/lib/modules/extensions/libglx.so
(II) UnloadModule: "glx"
(EE) Failed to load module "glx" (loader failed, 7)

glxinfo also complains about not finding GLX extension

My section "Modules" is:
Section "Module"
        Load    "bitmap"
        Load    "dbe"
        Load    "ddc"
        Load    "dri"
        Load    "extmod"
        Load    "freetype"
        Load    "glx"
        Load    "int10"
        Load    "record"
        Load    "speedo"
        Load    "type1"
        Load    "vbe"
EndSection

Ok, I have been building xorg cvs for a while and always used "make Everything".
I suspected imake may be doing ugly things and it turned out I was right - doing
make clean and doing a make World solved the error. Yet another proof that imake
sucks ;)


Now I get the following running glxinfo:

No old versions of anything are involved:

Everything worked OK in the past. I guess I will close this bug report and will
submit the new one in a new entry.
