I Also have this problem I have a Sempron 64 3400 running on an MSI k8T Neo v1 with ATI Radeon 9700 pro.
I've also experinced the same thing with live CD's for both PCLinuxOS and DreamLinux in both cases using the vesa driver overcomes the problem and once installed to hard disk the distro seems fine. With edgy however the safe grpahics mode (forcevesa) does not work. With edgy I can get my system to boot past the black screen by just commenting out DRI. -- [edgy][regression][rv280] black screen and console freeze when X starts - drm lockup https://launchpad.net/bugs/67487 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
