CTRL and ALT works as SHIFT?

Question

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.

Could you add more info, about your hardware, is it a laptop? Which brand & model? Are you using USB keyboard? — user.dz, Jul 15 '15 at 18:15

Install driver from https://github.com/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

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"
```
Update grub
```
 sudo update-grub
```
Reboot

This workaround will stop working after each kernel update. I described issue here. Do you have any solution? Thanks – DummyBeginner Aug 20 '16 at 15:50
What do you mean by appending it? should I use &, ; or just add it directly. I'm sorry if this is naive. It would be great if you could show how the line looks for you. – Ankit Singhaniya Nov 03 '17 at 17:51
@AnkitSinghaniya , use space as separator. :) no problem I added full example of the modified line. – user.dz Nov 03 '17 at 18:27
@DummyBeginner somehow late just noticed your comment. Check if installed it using DKMS. Verify using dkms status , is it listed there? – user.dz Jun 05 '18 at 20:48

If anyone is getting a 404 on the bitbucket link, there's a modified version on github which worked for me. – Sep 07 '21 at 12:44
@Meta Thank you, I update the answer with mirror that seem from same original author, in github. – user.dz Sep 09 '21 at 22:04
