Comment 7 for bug 398614

Can anyone that's experiencing this bug please try with the latest lucid daily-live CD (http://cdimage.ubuntu.com/daily-live).

Please reply with whether or not you were able to boot into the installer and the date of the CD that you used. If you were unable to get into the installer, please also attach /var/log/Xorg.0.log and /var/log/installer/dm to this bug report.

You will have to switch to a virtual terminal (ctrl-alt-F2), mount a USB disk, and copy the log files onto it. This will roughly consist of the following commands, substituting your USB disk for /dev/sdb1 where necessary:
sudo mount /dev/sdb1 /mnt
cp /var/log/installer/dm /var/log/Xorg.0.log* /mnt
sudo umount /mnt
