Diagnose Ubuntu 12.10 (in Dual 12.04-12.10 boot)

  • 772

I find that my Acer Aspire One D270 Netbook (Intel Atom CPU, 2GB DDR3 memory) shows a blank screen with a blinking cursor if I tried booting 12.10 from the bootable USB stick. In fact once, I clicked the "Try from CD" button, saw the blank screen for a while and had dozed off for an hour only to wake up and see the same blank screen again.

Then I installed it alongside my Ubuntu 12.04 (64-bit OS) and on booting 12.10, the same blank screen shows up and keeps me indefinitely waiting, until I run out of patience and press the power button, restart and boot my 12.04.

How do I correct this?

Here's what I found the last few lines to be, on scrutinising the problem via CtrlAlt1 as our friend here suggests:

mountall: Plymouth command failed
mountall: Plymouth command failed
mountall: Plymouth command failed
mountall: Plymouth command failed
mountall: disconnected from Plymouth
12.04

  1. Firstly:

    Try CtrlAlt1, and watch the text messages stream passes (as the machine starts). What error message do you see? What does it stop after?

    Possible Fix:

    Try CtrlAlt1, login (at the command line), and then run an OS update, to see if this is fixed by recent updates.

    Type: sudo apt-get update && sudo apt-get upgrade

    Lastly:

    You will need to do some further diagnostics ..

    With an Intel ATOM CPU, I will assume you are running 32-bit Ubuntu.

    (correction) This Acer model has the Intel Cedarview / Cedar Trail* CPU / graphics chipset, which is likely the root cause (anyway).*

    Can you provide details, from output of sudo lshw. (Note: This can be run from within 12.04 LTS, and still give much the same results.)

    UPDATE:

    The Acer Aspire One D270 does not support DX10.1, as the Cedar Trail GPU (graphics chip) only officially supports DirectX 9 (due to driver / design issues).

    The netbook is also sold with Windows-7 32-bit, and may not fully support 64-bit. It was left to the (PC/netbook OEM) manufacturer to choose to enable 64-bit, prior to the later S12nn series (Dec2012) Intel Atom.
