@Patrice: Okay, thanks. Then I'm sad to report that this has not fixed my bug.
The system isn't truly frozen: When I ran today's (13 March's) live CD, I still get the white screen of death. However, I can switch VTs to get a console. Should I supply a new batch of lcpci and log files to this bug report? -- [RV770 HD 4850] ATI Radeon HD 4850 not supported - white screen and system freeze https://bugs.launchpad.net/bugs/325394 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
