    small [how to] extend desktop ati 4500

    I saw some old threads online where people were having problems extending their display. (For me) It was as simple as:

    Turn on and hook up your external monitor.

    System -> Preferences -> ATI Catalyst Control Center (Administrative)

    On the left, under Pages I saw: this (click)
    +Display Manager
    Display Options

    I clicked "Display Manager"

    I then had something that looked like a laptop (with a 1) and a separate monitor (with a 2).

    When I say (with a 1), it's labeling your monitors 1 & 2.

    Below that I saw:
    Display Properties and Multi-Display

    I clicked the separate monitor (with a 2), and then Multi-Display. There was no reason to change any options for my current display that looked like a laptop (with a 1).

    Under Multi-Display (separate monitor (with a 2)) I clicked: "Cloned display from display(s) 1".

    My four options were:
    "Disabled display"
    "Single display desktop (multi-desktop)"
    "Cloned display from display(s) 1"
    "Multi-display desktop with display(s) 1" <-------- I selected this.

    And restarted my computer. Tada. Hopefully this will save people from installing 3rd party drivers. I just wanted an extended desktop to use so i didn't have to switch "windows" to compile when working on my projects. Good luck.

    Good luck

    I know this isn't hard for most people, I just saw that people were having trouble with it and figured I would post a quick tutorial.

    Thank you WMB, found your tutorial and it's quite helpful - but I have a question of course. Lo these many months later.

    Catalyst makes me restart, and then when I boot up again... it's switched to "Cloned display from display(s)", where everything is duplicated on the two screens. Which would be useful for presentations or co-op games but not so much for getting more workspace

    Any ideas? Or anyone else?

    @wmb, awesome tutorial

    currently, I am using 12.04 and one extra step is required to get the multiple display working. After you have restarted the computer, go to

    system settings - > Displays

    untick the mirror displays checkbox, click Apply and Viola!
