I'm trying to install Ubuntu 12.04, but when during the installation I face some difficulty regarding the step in which Ubuntu tries to take a picture using the webcam.

There is a window, when Ubuntu tries to take a picture and at that point the installation is interrupted. Should I look for a proper webcam driver? Or, should I find a way to disable the camera so that I prevent this step?

I'm using old Asus A8JN with a Core Duo T2300E, 2.5 GB memory and a 160 GB HDD.

I think that camera is "YaHsin Chicony" but i'm not sure.

and there is a line from usb-devices | grep Driver:

Welcome to Ask Ubuntu! This sounds like a bug, but of course there's a way to work around and disable this. We'll need more hardware information for that. Can you run from a live CD, "Try Ubuntu" and provide the output of lsusb run from a terminal? Also, the output of usb-devices | grep Driver should show one of the webcam drivers (e.g. uvcvideo). Do this by editing your question. I can provide an answer on how to disable this during installation then. –  gertvdijk Jan 30 '13 at 18:45

Below are steps to disable the kernel module (driver) for your webcam (gspca_vc032x), temporarily, using the initial boot menu of the Ubuntu Live image. It basically is just using the kernel boot parameter modprobe.blacklist=gspca_vc032x to do so.

  1. In the initial boot menu when booting the live image, press any key to enable the menu.
  2. Select your language; I chose English here.
  3. Highlight the option you want to continue using later (e.g. Try Ubuntu without installing). Don't start yet!
  4. Press F6 (Other Options)
  5. Press Esc to escape from this menu and start a custom editor of the kernel boot parameter line.
  6. The cursor should be at the end of the line now ending with --. Remove the two dashes.
  7. Type modprobe.blacklist=gspca_vc032x
  8. Press Enter ↵ to boot.

Alternatively, you can disable the kernel module after you booted as well.

  1. Boot Ubuntu (live image) the regular way.
  2. Before starting the installation, open a terminal.

    • Use the regular Terminal application Ctrl+Alt+T, or,
    • A virtual terminal, by pressing Ctrl+Alt+F1. Log in using username ubuntu and no password.
  3. Unload the kernel module to effectively disable the camera:

    sudo rmmod gspca_vc032x
    
  4. Close the terminal application, or, if you used the virtual terminal, go back to the graphical screen using Ctrl+Alt+F7.

  5. Continue as usual, starting the installation.
