Fresh install ubuntu ocelot (11.10) hangs on booting on dell XPS m1530

[Michiel Wittkampf]

I installed ubuntu oneiric ocelot from scratch (the option in the installer to replace the current ubuntu version.) Installing went fine (no problems reported.) But the system never totally booted after installing it. After some seconds, the (empty) purple screen appairs, and thereafter a text screen with some lines (I will attach a screen shot), and then nothing happens. I can only reboot from there using ctrl-alt-delete.

By using the the safe mode to boot, I was able to reach the command line. I used apt-get to do the available upgrades. That made no difference to the above.

Does anyone else experience this?
Does anyone know the solution?

Thank you for taking the time to report this bug and helping to make Ubuntu better. While we appreciate the difficulties you are facing, it would appear that the CD image (ISO file) you downloaded could be corrupt. There is an easy way to verify the integrity of the Ubuntu ISO files you download. Could you please visit https://help.ubuntu.com/community/HowToMD5SUM follow the instructions and report back as to whether or not the MD5SUM verified? Thanks in advance.

Also please tell if the live session works regularry, if works, run again the installation from it, at the end don't reboot, but attach here using the button below 'Add attachment or patch' the files in /var/log/installer
Thanks
Fabio

Hi Michiel,
  Given that the install completed with no errors, I disagree with Fabio; I doubt the issue is your CD image.

I've seen people with similar problems, e.g. bug 804171 where the problem is lightdm not starting.

Could you please attach to the bug the contents of /var/log/lightdm
You might find that lightdm.log contains a lot of hints as to the problem.

Dave

Hi both,

Thanks for responding so quick, helpfull and clear.

First: the problem seems 'fixed'. I (re)installed three times. The third time after Fabio's post. Only thereafter booting went fine.
To help in the event that the problem reapears in someone elses or my computer, I will still give the feedbak you asked for.

Fabio, the checksum was oke.
The /var/log/installer files are attached.

Dave, the /var/log/lightdm files are attached.

What happened:
The live session started fine (first it didn't.) Thereafter I installed the system. I did reboot (after saving the files Fabio asked for.) And all worked fine.

The difference with the second time I installed the system was:
- In the bios I disabled all wireless functions in the laptop
- I didn't let the installer install upgrades
- I installed when I was in a live session

After the system was installed and I had rebooted, I turned on the wireless functions in the laptop bios. And I installed all available upgrades.

I don't know if the above made the difference. But these are the only differences I am aware of between the install which does work and the one which didn't.

Thanxs for hinting me in a direction which turned out to be a suprise solution!

Thank you for the update, did you get those log from the working install or a broken one?

I got the logs from the working install.

11.10 is end of life.
