Additional info: 1. ctrl-alt-F1 apparently does work, but the screen remains blank. After ctrl-alt-F1, "username\n password\n sudo reboot\n" does cause a reboot. It appears that the system is working, but the screen is displaying black on black after graphics mode is entered.
2. Booting older release 2.6.31-20-generic does succeed in bringing up graphics. I thought that I had tried this release previously, and that it had not worked. I have installed several updates since then. In summary, in 2.6.32-16 graphics screen goes blank after initial boot messages, but now appears to work OK in 2.6.31-20. -- graphics hang blank screen on lucid boot https://bugs.launchpad.net/bugs/542208 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
