Virtual machine created from a dd image of a NUC machine doesn't start Xorg

  • 772

I created a dd if=/dev/sda image on an NUC running a possibly customized Ubuntu 15.04. The NUC has 2 GB RAM, 16 GB SSD and runs on Intel Celeron 1037U.

I created a new virtual hard disk and dd'd the image to that virtual hard disk in another running system, and then created a new virtual machine on this restored virtual hard disk.

The problem I'm having is, the virtual machine does not start normally and gets stuck at this screen. The Last login line updates every 15 seconds. By examining $HOME/.profile, it seems it's stuck at this line:

exec startx &> ~/.xsession-errors

Checking the logs it appears like that the display (screen / monitor) has changed and Xorg doesn't work with that, but I am not 100% sure.

mmm

Here's the tail of the file /var/log/Xorg.0.log

Note: I am able to attach this virtual disk to another VM and chroot into the system inside and investigate for issues. I have managed to install open-vm-tools after chroot-ing into the system but still same problem.

How do I boot this VM up?

vmware xorg

    After a few hours hard work Googling this problem, I found this page that contained information that help me solve the problem.

    Just move the Xorg configuration file (to save it as a backup) and reboot:

    sudo mv /etc/X11/xorg.conf /etc/X11/xorg-old.conf

    Then Xorg will try to detect any new devices.
