Description (last modified by jdreed) (diff)

See ATN-57 (attached in PDF) for context. 3D applications have window refresh issues.

Gaussian, ac3d and Maya are much more usable under Jaunty than Intrepid, but Gaussian still complains in the console.

The 755s (with radeonhd) are fine, and the 760 is fine with the radeon driver. This really only affects the 745s. I don't want to get in the business of forcing fglrx on one type of hardware only.

I propose we document the brokenness and encourage people to use a 755/760.

The 745s are with us until at least 2011, so maybe we should do something about this. But at the moment, I favor waiting until Karmic to see if the radeon driver works better there. Then we can decide if we want to go down the fglrx road or not.

  • Resolution set to wontfix

We decided at release-team we really don't want to start drinking the fglrx koolaid again, because it totally sucked with Athena 9. Using the Ubuntu packaging of fglrx in Karmic might be ok, but the drivers in Ubuntu are already old when they come out, and have a number of known issues. (See  LP:366687 among other things) We definitely don't want to go down the road of packaging our own release of fglrx.
