For what it is worth, I had a similar problem after an 'apt-get upgrade' a few days ago. I booted, saw the B/W ubuntu logo, and then the screen changed to a text mode, showed some services starting, and then started flickering incessantly. I was unable to change to a different VT and log in (it was missing key inputs - presumably because it was switching back to VT7 for X).
Unlike the others here, my Xlog.0 file indicated that the (restricted) Nvidia drivers weren't able to load. I was able to boot using an older kernel selection from Grub. I was also able to boot using the Beta .iso image on an USB stick. It seems that for some reason, the nvidia drivers weren't rebuilt when the kernel was upgraded during the 'apt-get upgrade' I ran yesterday to move from Alpha 6 to Beta 1. A 'sudo dpkg-reconfigure nvidia-185 -kernel-source' ended up fixing the problem for me. I only mention it as it seems that many of the problem systems are using Nvidia chipsets. At this point, I'm assuming it was a one time glitch and don't plan to file a bug report. Please let me know if I should do otherwise. -- Karmic boot hangs before login https://bugs.launchpad.net/bugs/428920 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
