Recently I installed debian on a separate drive on my desktop. My keyboard worked in the grub menu but not in the installation menu (I figured this was a fluke and pulled out an old ps/2 keyboard which helped me finish my installation).  Then I booted into the drive and my keyboard worked in grub. I'm then presented with a password prompt to decrypt but the lights on my keyboard flash and it doesn't work. I login using my old keyboard and my regular keyboard still doesn't work inside the OS. What I tried:Enabling Intel VT in BIOS,Enabling legacy support in BIOS,appending 'noapic' and 'nolapic' on 'linux ...' in grub - side note, I restarted to see if the changes stuck and they weren't there.Please help, I need this keyboard to work as it is an adaptive keyboard
