If some kind of more sophisticated card detection is going to be done for feisty's automatic X configuration, and no-one is interested in fixing this upstream, this could be easily solved by choosing "radeon" driver instead of "ati" for at least X300-X800 cards.
And no, fglrx should not be used for these cards, since there's a working open source 3D driver available - open source drivers are meant to be used in every place where it's not absolutely necessary for 3D, meaning currently using binary drivers for ATI X1300-X1950 and all NVIDIA cards. -- X fails to start in dapper, edgy with ati X600/X700/X800 (control not delegated to "radeon" driver, "ati" complains about Mach64). https://launchpad.net/bugs/28925 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
