Ubuntu – CTRL and ALT works as SHIFT

driverskeyboard

A few hours ago, I installed Ubuntu 14.04 alongside Windows 7.
Everything went fine, installed all my games and programs. But, then I realized that ALT + TAB, CTRL+ALT+T key combinations (as well as many others) do not work.

This is really annoying since I like to use ALT + TAB for multitasking. Anyways, I realized that they were mapped as SHIFT because as you know, if you hold SHIFT and press any key, it will be in CAPS. So that's what happens when I press CTRL or ALT.

It's a custom-built desktop. I'm using a GAMDIAS USB keyboard.

  1. Install driver from https://bitbucket.org/Swoogan/aziokbd

    sudo apt-get install mercurial build-essential linux-headers-generic dkms
hg clone https://bitbucket.org/Swoogan/aziokbd
cd aziokbd
sudo ./install.sh dkms

  2. Add kernel option to grub to prevent usbhid from being used for this keyboard. Append:

    usbhid.quirks=0x0c45:0x7603:0x4

    to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub.

    Example:

    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash usbhid.quirks=0x0c45:0x7603:0x4"

  3. Update grub

    sudo update-grub

  4. Reboot
