Saiph, have you seen this link: http:// stevesubuntutwe aks.blogspot. com.au/ 2013/10/ laptop- keyboard- stopped- working- after.html?
From that article:
A bit of head scratching, and plugging in a separate USB keyboard allowed me to type again. But that isn't quite an optimal solution. A bit of Googling led me to the following bug report for someone else with an LG laptop. Going by the eighth comment in that, it turns out a couple of options have to be added to the grub menu, by editing the /etc/default/grub file. In my case, the file had the following line:
GRUB_CMDLINE_ LINUX_DEFAULT= "quiet splash"
I added two options to the end, so it became:
GRUB_CMDLINE_ LINUX_DEFAULT= "quiet splash i8042.nopnp=1 i8042.dumbkbd=1"
Saved the file, and ran sudo update-grub to let the changes apply, and rebooted. I am now typing this blog post on the working laptop keyboard!
