I should add, when xorg.conf is altered so that DefaultDepth (in section "Screen") is set to 24 X will start successfully.
As I understand it, with the i810 driver set to 24 bpp, it causes DRI to be disabled. I had it configured at 16 bpp to achieve DRI originally. So, to work around this bug, the system loses direct rendering; hardly a satisfactory situation. The xorg version is 7.1.1 date May 2006, so I'll investigate later versions if possible to see if this has been fixed upstream. ** Attachment added: "Xorg.9.log with failure report at end" http://librarian.launchpad.net/5806263/Xorg.0.log -- X fails to start, agpgart error https://launchpad.net/bugs/80792 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
