ctrl, alt and super keys bug

**Austerity** · 2017-01-07

Hey, I just installed kali linux 2016.2 on my computer.
After messing around with it a little bit I found out that the ctrl, alt and super keys all act as if I pressed the shift key.
For example if I press CTRL-A it types in a capital A as if I pressed SHIFT+A.
That means alt-tab doesn't work for me as well(registers as shift+tab), ctrl+f doesn't work as well and most of the keyboard shortcuts are messed up...

Does anyone know how to fix this problem?

i have the exact same problem.. I searched the whole internet to find a sollution, but nothing i've tested have worked for me.. tried it with xkb to remap the keys but i can't do it couse when i press any of the keys it gives me the same input as SHIFT L, and SHIFT R also acts as SHIFT L..

I've tried the USB Keyboard on my second PC which has W7 installed and everything works fine..
here are some info:

@vu4rac0d3 , I run into the same issue with you, and my keyboard's model seems like yours. The vendor id and product id of my keyboard is

, comparing your

I'm running Ubuntu 17.10. It is a driver issue and not relative to a specific distro.

In

Code:

xev

, all of "CTRL_L CTRL_R ALT_L ALT_R SHIFT_R" produce keycode 50, aka Shift_L.
Super key didn't captured by xev, but it acts just like Shift key.

Code:

KeyPress event, serial 37, synthetic NO, window 0x4e00001,
    root 0x1de, subw 0x0, time 39030998, (106,-11), root:(223,96),
    state 0x0, keycode 50 (keysym 0xffe1, Shift_L), same_screen YES,
    XLookupString gives 0 bytes: 
    XmbLookupString gives 0 bytes: 
    XFilterEvent returns: False

KeyRelease event, serial 37, synthetic NO, window 0x4e00001,
    root 0x1de, subw 0x0, time 39031070, (106,-11), root:(223,96),
    state 0x1, keycode 50 (keysym 0xffe1, Shift_L), same_screen YES,
    XLookupString gives 0 bytes: 
    XFilterEvent returns: False

Did you solve the issue now?

I found some links on Ask Ubuntu, all refer to https://bitbucket.org/Swoogan/aziokbd , but they are all for 0c45:7603 devices, I don't think they will work for me.
