This bug-report seems to contain different bugs... I have the same problem as stefano fabri in the AMD-64 version in Feisty Herd-1.
In the i386 version (for Feisty) I filled a new bug-report, which is just a duplicate of the main problem. The "ati" does not work .... https://launchpad.net/ubuntu/+bug/77565 (It has links to even more duplicates...) -- 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
