Comment 7 for bug 513950

Hi Jamie,

We're not going to have this fixed for Alpha 3. However, I took the
matter of this bug up with David Airlie upstream, who told us we need to
pull the latest DRM code from the .33 kernel in order to fix this bug
and many like it. It seems a lot of kms stuff got rushed into .32 and
is pretty buggy, especially with older or unusual hardware.

I brought the kernel guys in on this discussion, and while there was
heavy skepticism that this was just upstream pushing us to bleeding edge
stuff yet again, in this case we have assurance that .33 has been a
stabilization release and thus is an appropriate solution. The question
remains whether the kernel team will backport this drm code en masse to
the .32 kernel, or if instead it would be put in
linux-restricted-modules for users to opt-in to as needed. There wasn't
time to do either one of these in time for alpha-3. I think we're
leaning towards the former, but the decision will be made after alpha-3
is out.

Even phoronix has picked up on this debate and written about it:

So in case you think your bug is being ignored... quite the contrary.
But it's that piece of yarn which unravels the whole sweater.

One thing you could do for testing, would be to install and try Andy's
drm backport and give me feedback on it:

I don't know if simply installing this is enough, or if it'll require
additional configuration of bits and pieces, so be aware it could be
time consuming to set this all up properly... or it might just magically
work.

Otherwise, I'd say sit tight, it'll be a week or so before we can get
this drm available in Lucid and integrated to a point where we'll be
confident it can be easily tested.

This worked but after double clicking on the Screenshot.png on my desktop, X froze. I could ssh in, so I ran 'ubuntu-bug xorg' from there. I do not have an xorg.conf file.
