Okay, uploaded the files that were requested of me. I had to boot a dapper live CD (received in the post today, along with stickers, neat!) in order to get these, and the live CD froze on starting X also, but succeeded on (I think) the second attempt to boot.

Thanks for helping.

More info about the bug as I'm experiencing it:

* At a point late in the ubuntu boot process you're on a black screen with a blinking cursor in the top left, this occurs briefly before GDM appearing. When the boot fails, it freezes at this black screen, and the cursor stops blinking. There's nothing I can do except kill the machine with the power switch (this can't be good for my old laptop).

* The bug doesn't seem to be specific to any flight of dapper or to the live system or installed system - I've experienced it quite reliably with a couple of dapper flights and with the dapper release, and with live sessions and installed sessions.

* It doesn't seem to make any difference which kernel I boot from (I have two ubuntu kernels installed, don't have the exact versions sorry, plus rescue modes for each). If I boot into rescue mode I'm taken to the root prompt fine, but the bug will occur when I run startx.

* The bug seems to be intermittent. If I just keep booting it, sometimes GDM will load and all will be fine, but most of the time it'll freeze. There doesn't seem to be any particular condition that makes it fail or succeed.

* I've used this laptop with release and pre-release versions of every release of ubuntu, and never noticed this problem until dapper, so it seems to be something new.

Thanks!
