Still can't boot Lucid

[Tony Pursell]

Hi All

I know I have asked about this before, but I am becoming desperate. Since I upgraded my desktop from Karmic to Lucid I cannot boot into Ubuntu. I have been trying all sorts of things without any success.  I have a bug [1] that has not received any attention. I now know that it boots only to a point where no log files have been written.  You can see from my photo of the console screen that there is a sort of error message at the point it gives up.  This is the subject of another bug [2] but I don't think it is the primary cause as I know you can still boot after this report is produced.

What I can do is boot into Lucid from a USB stick, so there can't be a fundamental problem with my desktop PC.  I can also boot into my remaining Karmic kernel using the recovery option and get myself logged into a console. So I can tweak config files, if required.  But with this kernel I can't run anything graphical (either through the normal boot or by running startx) because mouse and keyboard don't work.

One thing I have explored a lot is the possibility that it could be due to Kernel Mode Setting (which is the norm in Lucid), but disabling that in the boot parameters just results in my monitor complaining about the resolution settings and going to sleep.  So if it does boot, I can't see it!  Anyway, the fact that I can boot from the USB sort of rules KMS out as the cause.

So what is different about my desktop PC's Ubuntu installation that might set it aside from other installations that have been successfully upgraded.  Two things come to mind.  First, it is a fully partitioned installation with separate root, usr, opt, tmp, var and home partitions. Secondly, it has Xubuntu installed alongside the standard Ubuntu. This has the effect that it starts booting with the Xubuntu splash screen (it did the same after my Karmic upgrade, although it ran Gnome after login).

Can anyone think of why I cant boot Lucid?  I would be grateful of any suggestions.

Tony

Hello, Tony.

Have you tried "acpi=off" on the kernel command line?

Bye,

I think I have tried that.  I got a list of Kernel parameters and tried
most that looked as if they might do some good.  But I will give it
another go.

I have tried acpi=off and it has no effect.
