Comment 25 for bug 277587

Russ, good to hear that the issue for you is solved with jaunty.

Hanging at the "Check battery state" message is a generic symptom that can be caused by a variety of very different kinds of bugs. Judging from the comments so far, it sounds like several people sorted them out as being due to one thing or another (e.g. having had -fglrx installed).

If anyone is still having this issue when trying to boot on jaunty, please file a NEW bug. We really need to have the log files and other information in order to conduct troubleshooting of these bugs. With a LiveCD, obviously this can be difficult, but the trick is to either switch to a console (ctrl+alt+f3) or boot into recovery mode to a console prompt. Then you can collect 'lspci -vvnn>lspci-vvnn.txt', /var/log/Xorg.0.log, /var/log/Xorg.0.log.old, and /var/log/gdm/* to a usb key or copying them across the network to another machine.

To get your system up, often you can switch to the vesa driver. For more information on doing this, and troubleshooting this kind of issue in general, please see the documentation at http://wiki.ubuntu.com/X/. The config and troubleshooting guides can be of use here, in particular.
