This bug is mainly about the problem when X doesn't start and /var/log/Xorg.0.log shows the following kind of lines: (WW) ATI: PCI Mach64 in slot 8:0:0 could not be detected! (WW) ATI: PCI Mach64 in slot 8:0:1 could not be detected! (EE) No devices detected.
Ie. the upstream bug is about that. -- 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
