When I run the live CD installer, the installation gets stuck at "select a picture for the specified account." I've found that is an incompatibility problem with my webcam and the only way to fix this is running the Terminal command:

sudo modprobe -r uvcvideogp

This must be run before doing the installation. But because its a live cd, I don't know exactly how to do that. I've tried opening the terminal normally and executing this command, but I open the setup and still stuck.

How can I run this command in a Terminal on the live CD?


Select the option Try Ubuntu without installing from the boot menu when you start up the live CD, instead of the Install Ubuntu option. Then you boot into a usable Ubuntu desktop which runs as 'live.' From the desktop, you can open the Terminal (Ctrl+Alt+T) and run this command. Then when you're done in the Terminal, start the Install process by double-clicking the Install Ubuntu icon on the desktop.

That is the best way to do it. But if you ever need to enter a command after you've already selected Install Ubuntu instead of Try Ubuntu without installing, then you can run it in a virtual console. Press Ctrl+Alt+F1, and you'll get a text-based screen where you can enter commands. Press Alt+F7 to return to the graphical user interface. Commands that are doing work in the one virtual console (e.g., the 1st one, accessed with Ctrl+Alt+F1) will continue to run even after you've switched to a different virtual console (or back to the GUI).

    @Eliah Kagan, thanks for adding the second paragraph. but I have one doubt, if we take the virtual console by using Ctrl+Alt+F1- would we get the terminal directly or the screen to input username and password. The issue is whether it would ask for username and password. – saji89 May 24 '12 at 16:35
  • For ubuntu server, there is no 'try ubuntu without installing' item. What should I do now?! – Dr.jacky Dec 7 '15 at 8:26

    @Mr.Hyde, As far as I know, unfortunately, Ubuntu Server, does not have such a facility, allowing commands to be run before installation. – saji89 Dec 8 '15 at 12:12
