Comment 25 for bug 247003

Your Module section looks fine. You can verify in your log that the module is not tried to be loaded like before.

Your glxinfo shows GLX_EXT_texture_from_pixmap which they talk about in the bug I mentioned. So I guess it is somewhat related and it will be fixed in Intrepid soon, with mesa 7.1~rc3-1 or newer (commit 4fab47b13c214dc79e0ae5d8001521029ce34231). I'll therefore set the bug to "fix committed", and please report back once you have tried the newer mesa.
