I have purchased a Corsair Strafe keyboard and here is what happens when I use it with Ubuntu PC:
It works fine when selecting entries from grub. Then it is again working properly while logging in. But it stops working when I get to desktop after successfully logging in. How can I fix it?
Since keyboard is not working inside system I don`t know how any further investigation be possible.
Here is the output of lsusb:
Bus 004 Device 002: ID 1b1c:1b15 Corsair
