I also had issues booting Natty final 64bit Live CD on ATI Radeon HD3400. I get the boot menu, choose "Try without installing" and then, after some time, the screen freezes and the OS is unresponsive esponse to keyboard or mouse. Adding "nomodeset" to the boot line worked fine for me, the Live CD booted into Classic GNOME. After installing Natty onto the disk, no more tinkering of boot options was necessary, everything just worked fine after that in my case.
If it helps, I am using a Sony VAIO FW series (never had Ubuntu related problems with that one before). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/763909 Title: 11.04 Wont Boot With Mobility Radeon HD 3400 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
