    Exclamation Installed Ubuntu 12.04, No USB Keyboard or Mouse

    Hi All,

    I installed Ubuntu 12.04 LTS on my new Inspirion 2020 All-In-One as a dual-boot with Win7. At the grub menu I can use the keyboard to make my selection. When I go into Ubuntu, I get the logon screen but I cannot use the keyboard or mouse. It's a wireless keyboard/mouse.

    Anyone know how to get them to work?

    Thanks!

    Sidebar: The keyboard and mouse worked with no issues from the USB stick that I booted from to perform the install.

    What model/brand USB Keyboard/Mouse? Logitech? And is it the Unifying Receiver or two separate usb wireless dongles?

    It is the stock wireless keyboard/mouse and USB receiver that comes with the Inspiron 2020. It's Dell.

    Have you tried any other usb devices in the port that your wireless usb is plugged in? Or have you tried moving the USB dongle to another port?

    Sometimes there can be signal issues with a rear port on desktops.

    Thanks for your reply. Yes I tried other ports with the USB dongle and no luck. I also trIed plugging in a wired keyboard and mouse and same results - no connection.

    These were from booting my machine from a Live USB stick. If I boot from the Ubuntu part of the dual-boot, I can't move the mouse or use the keyboard to get output.

    Thanks!
