This appears to be an issue with the xorg video driver, which arose for
some reason when running in combination with 3.2.0-31 and subsequent
kernels, but not with earlier kernels.
It turns out that the laptop is not dead, but just that the screen does
not work at all. I can do CTRL-ALT-F1 to get

I am also attaching the Xorg.0.log files, from a failed and successful
boot, again also with versions which have the timestamps stripped and
the lines sorted alphabetically.

Unfortunately I spoke too soon again - this is an intermittent problem
and it occurred again this morning (I have now upgraded to Quantal with
kernel 3.5.0-17-generic).
I have collected dmesg log files from an occasion when the problem
occurred (the screen went blank during the boot process), and

I think this problem is now fixed. I was previously having problems
with CPU lock-ups on my laptop (an HP Pavilion dm1-4020sa), and had
fixed the problem by blacklisting the sp5100_tco driver, and disabling
the thermal module (as discussed at

package updates listed above have not completely solved the issue.
The failure to boot does seem to be happening less frequently now,
though. I imagine that this is something to do with how the video

I upgraded a number of packages on my laptop this morning, and I think
these updates may have solved the problem. I've booted the system 6-7

I reinstalled kernel 3.2.0-31-generic-pae and changed the boot options
