Comment 5 for bug 180423

We'd also like to check whether or not this is a bug with the GUI or with the kernel.

Please could you try booting from the CD again. When the menu for the CD comes up, don't choose to "start or install" ubuntu yet.

Instead, press f6.

You will see a line of options written at the bottom. With the keyboard, navigate to and delete the words "quiet" and "splash"

Write the word "single" where they were.

The computer will start in a command line interface. Please could you let me know if the keyboard works here

If it does, you can shutdown by typing

sudo shutdown -h 0

If not, try pressing the power button, it should send the signal to perform a shutdown. If it doesn't you might have to hold in the button for 6 seconds.

Either way, please report your findings.

Thanks again.
