Ubuntu hangs on boot, with the ubuntu logo displayed (plymouth)

[fcole90]

Since the recent update of linux to 3.13.0-35 my laptop hangs on boot. I tried to boot with version 3.13.0-34 and it works correctly. So I think that the regression is between version 3.13.0-34 and 3.13.0-35.

The problem seems to be solved upgrading the package xorg-core that was not upgraded when linux was updated (the reason is unknown, I have upgraded from the upgrade manager, while I upgraded xorg-core from synaptic).

The problem was solved also removing nvidia-drivers. Installing nvidia-331 drivers the problem happens again. I worked until version 3.13.0-34 of linux. A bug for xorg has also been opened: #1365907

Fabio, thank you for reporting this and helping make Ubuntu better. As per http://www.packardbell.co.uk/pb/en/GB/content/download an update to your BIOS is available (1.20). If you update to this following https://help.ubuntu.com/community/BiosUpdate does it change anything? If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report.

For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette .

Once the BIOS is updated, then please mark this report Status Confirmed.

Thank you for your understanding.

I'm going to try to update my bios. I want to add that I have noticed that on 34 the drivers where not enabled. So in both versions without drivers the session is loaded correctly. The problems come when I install the nvidia 331 drivers and nvidia prime. It seems to work also installing 304 and bumblebee but I'm still investigating. Anyway the problem seems to not be related to linux image but something else that maybe messed up with libraries and or dependencies.

I have reinstalled ubuntu in the same partition but the problem was still there, than I tried to install on a different partition and the problem vanished. It's definitely a misconfiguration problem.
