I hit ctrl alt f12, screen went black and I powered down my hp hdx 16 laptop by holding the power button down. Now Ubuntu shows no network devices available and I have no internet wired or wireless even when booted into the live cd. Ubuntu 10.10 64bit. Thx.

I put lshw in terminal and got:

*-network DISABLED
description: Ethernet interface
physical id: 1
logical name: vboxnet0
serial: 0a:00:27:00:00:00
capabilities: Ethernet physical
configuration: broadcast=yes multicast=yes

Sounds like this may be the issue, how would I go about enabling this?

Can u do
$sudo lshw -C 'network' instead. The listed above is virtualbox interface.

It's exactly the same. I was running pclinuxos in vbox when I was trying to hit shift alt f12 to toggle desktop effects when it happened.

Then u might have to go thru dmesg. ur network interface was not recognise. Try providing as much info as possible on networt interface type, model.

It's working now after booting into the live cd a second time. When I restarted from the live cd I noticed the restart screen had a lovely resolution and looked really nice compared to my pixelated boot screen currently seen in my Ubuntu 10.10 install. How can I get the same resolution on my install?

What are you refering as boot screen? The screen where u see the dots?

So can we say that your network interface issue is solve?

The dots as well as the power down screen or whatever you call that. Network devices are available, I have a feeling it was simply from powering down the laptop with the button, weird that it took so many restarts and two live cd boots to get it back tho.

Purple backgrounds, it's no big deal really, I tried a tutorial but didn't work. Wireless was my main concern. Thx for the help tho.
