I don't know who you were directing the "what graphics card" question to. .
. but my MSI Wind U100 which has the flicker problem has an Intel GMA 950.
It's the only computer I have with that issue. It was reported to Canonical
months before the final version was released, but never fixed.
Some blamed MSI but since even beta Lucid works flawlessly on my Wind I see
it as a true bug that should have been resolved and not just 'triaged'.
