IIRC, in one of the previous incarnations of this particular thread, someone
somewhere mentioned that this is actually a bug in the version 290 of the
nVidia drivers. I remember looking at the bugreport to nVidia (lost the link,
sorry...), and it was recognized as a bug and also closed as FIXED by nVidia.
Of course, the new version of the driver with this fix is yet to be released by
nVidia, and in the meantime users that are being hit by this were advised to
downgrade to version 280.
The problem was that nobody on the list could walk Lawrence through the
downgrading process (as you have probably found out, it's not exactly a thing
a newbie would be able to do easily).

The AIGLX option is a good thing if it works, keep it. I wouldn't know about
the ignoreABI option, but maybe it is necessary for the downgraded driver.
Lawrence should keep in mind that he should update his driver to the latest
version as soon as it comes out of nVidia, and that the issue he is having is
probably going to go away on its own... ;-) In the meantime, he should keep
using the 280 driver, and probably keep running the current version of the
kernel, until the new driver arrives.
Best, :-)

Darn, I missed the bugreport on downgrading to the 280 version, that would have
made the time spent *hours* less. In any case, he's
working now and we discussed going forward when a new driver comes out. While I tend to
agree with going with the newest driver I
will, as I typically do with anybody when discussing these sorts of things, advocate
letting *others* be the guinea pigs and wait to
see if anything shakes out after it's released before upgrading to it. He has a
working system now and I wouldn't want to see that
go away with another buggy driver.
Thanks for the info Marko. I'll have to check more carefully in the future.
