Description Andy Wingo 2008-06-25 20:45:20 UTC
Hi. I'm running Fedora 9, with the latest updates. I removed my
/etc/X11/xorg.conf, so I should be running with defaults. Things are working
grand except that the texture_from_pixmap extension, although advertised, does
not appear to work.

I cannot make it work in my own code. I cannot make it work with Clutter's code
(clutter/test-pixmap in SVN). If i build git compiz and run that, it shows only
a white window.

In all of these cases, it prints out "failed to create drawable" on stderr. This
printf comes from mesa, in src/glx/x11/glx_pbuffer.c:	   fprintf(stderr, "failed
to create drawable\n");. That's about as far as I have been able to dig.
Clicking on "desktop effects" does seem to work, in that there are shadows and
stuff, but I have no idea how, if compiz does not work from git.

What's the deal? I can only think that the driver is borked.

try using LIBGL_ALWAYS_INDIRECT=1 ./app

you can't do direct rendered TFP yet.
