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
