This is a big one, folks!
The Intel graphics driver is one of the most important in a distribution, as many many people use Intel-based graphics hardware. There are extensive changes coming to the intel driver in Fedora 11 - see the feature page for some details. Tomorrow - apologies for the short notice - we will be having a Test Day for the intel driver, in #fedora-qa on Freenode IRC as usual (see how to use IRC). You will, unfortunately, need Rawhide to test - there's too many changed components to backport to Fedora 10 for testing. Rawhide isn't installable today. It may work tomorrow, but you'd be best off installing Fedora 10 or Fedora 11 Alpha and then updating to Rawhide via yum (see this known issue for upgrading to Rawhide from Alpha).
We really really need wide testing of the new Intel driver stuff for 11, to make sure it works on all (or at least most...) hardware. If you have an Intel video adapter, please ideally come out to the test day tomorrow, but even if you can't, take a look at the Wiki page, run through the tests listed there, and submit your results - it's all documented on the page and it should be easy to step through. We need you to help make sure this is working well. Thanks a lot.
