Well, this is the third or fourth upgrade to Squeeze from
Lenny I have
attempted, and they all have been painful. This one has failed,
though. I upgraded and got everything working, but then I decided to
clean up a bit. I did a couple of runs of `apt-get autoremove` and
an
`apt-get upgrade, along with installing startupmanager. I removed
the
old 2.6.26 kernel image, and then updated Grub. Then I rebooted the
machine. Grub comes up, and if I let it boot to Windows, it works,
but if I select Linux (normal or recovery), very shortly after
starting to
boot the video output from the machine just dies. I don't mean it
goes blank, I mean the video goes away altogether, as if the machine
is shut
down. The monitor reports a loss of video signal, yet the PC is
still running and continues to access the hard drive.

When it was working, the machine would start out in text
mode, but
quickly would switch to graphics mode when booting.



Do you mean when the console text mode switches fonts (to the uglier
but
more readable font), or when X is started? That is, is the first mode
set failing, or is it the second one, the actual switch to the
desktop?
If the latter, boot to single-user mode and investigate. If the
former, you need to intervene during the boot process by telling the
kernel what text mode you want manually (boot parameter).

The former. I know where and how to change this, but what is the
syntax? The attempts mentioned below were a shot in the dark, since it
seems the failure is right about the point where the initrd loads.

I am not certain,
but I think it is at this same point the video output dies, now.
I've tried booting from the installation CD and removing then
re-installing
xorg, kdm, and kdebase. No joy. What should I try, now?

I captured the dmesg and syslog files, but nothing jumps out
at me. Is
there something specific for which I should look in the logs?
