No direct rendering on Dell Latitude 110l laptop (i810)

[Daniel Robitaille]

Direct rendering is not turned on by default on a Dell Latitude 110l laptop
after a new Dapper installation (using Flight 1).

On the same laptop, direct rendering was working by default in Breezy, using the
exact same xorg.conf file.

Same problem here, same conditions, but with a Toshiba Satellite M70 laptop [1],
with an i915GM video card.
As you can see from the Xorg.0.log, direct rendering appears to have been
enabled, but glxinfo does not see it.

This is almost the same config file as Robitaille's. The only different thing
are the resolution (1280x800 instead of 1024x768) and the keyboard layout.

You didn't send your Xorg.0.log. Does yours too say that direct rendering is
enabled?

Thanks for your "clues" :-)

Installing libgl1-mesa-dri has solved the problem for me (and I guess it would
work for Robitaille too). That's what happens after getting used to Ubuntu's
"everything working out of the box" experience :-)
