Public bug reported:
Binary package hint: live-installer
Got a display issue with Nvidia driver, and in trying to follow
instructions, the system suddenly reverted to low resolution mode on
bootup, and nothing works to fix it. Not that I really know what to do,
which is why it is such a problem. Not even sure how to mount another
partition with a working install so that I can compare details.
Anyway, there is very little said about how to rescue a broken
installation, except that it should be possible. I refer to
https://help.ubuntu.com/9.04/installation-guide/i386/rescue.html in this
regard.
AS far as I can tell at this point, there are only two options for
booting from a live CD with Ubuntu 9.04 on it. First you have to get to
a text-base mode, and the method for doing that is not obvious. I found
it as toggling down to Install Ubuntu as my choice option from the
start-up screen, then hitting the Esc key, which offered me a chance to
exit the GUI mode and go to text mode instead. So i did that.
next, I had a black screen with this showing:
Boot:
Boot what? No choices offered. I tried several names that I could
think of, but the only response was that it could not find an image with
that name. I did not know what to do to get a list of available images.
Finally, in desperation, I typed help, and that worked. I suddenly had
a help screen, similar to but not the same as the one in the GUI. I
tried F1 for more help, and got a differentl list of possible options.
There was one for dealing with a broken system, but you pick that, you
only got told that it was do-able, but not how. However, I had the info
from the link above (only obtained with the help of another PC with
online access), so I decided to try both the boot and the
rescue/enable=true options mentioned.
Boot was not valid. No image by that name. Rescue/enable=true not
valid either, as no image callded rescue was found either. Somehow I
stumbled on the fact that there were just three images identified, one
called live, the second called live-install, and the other something
else, but it only tested the PC memory. I've been through so much
lately that some details escape me.
Anyway I decided to give live-install rescue/enable=true a chance, and
it seemed to work. Up to the point of where the partitioner got called
in. Instead of seeing a different drive view where my choices were
which partition to rescue, and no notice of the fact that this was just
a rescue effort and my data would remain intact (as promised in the link
above), I only had the choices of which method to do a fresh install
again.
Now I know that if you pick the manual mode, then hand select the
partition to be used as root (/) but not to format it (leave that box
unchecked), then you will we warned (advised maybe?) that only the
system files will be replaced. Well, that could work, but I've already
found (and reported in another bug report) that the partitioner screens
are so stretched left and right, that the key box of Forward goes clear
off screen. So you can still use Alt+F to go up to the point of
actually performing the install, but no further.
I guess I will go back and try with the boot option of live
rescue/enable=true and see if it flies, but my expectations are not that
great, in fact lowered simply because the live approch already assures
someone that no changes will take place with the hard drive contents.
Sure looks like the ability to Rescue a Broken System is nothing but a
myth at this point. You have no plan in place to do so, none that any
novice or semi-competent person can fathom or make use of.
I would certainly call that a bug worth reporting. And it also points
up the severity of the previously reported bug as well, because now it
hinders efforts to restore a damaged system.
