Keyboard not working on a Samsung 300e5a laptop

I tried to install Ubuntu 12.04 on a Samsung 300e5a laptop. The keyboard was not available during the installation, i don't know why, so i thought that it was just a glitch, and i used to virtual keyboard to finish the installation ( login, password ... )

I thought that the keyboard will be enabled at boot, but it still doesn't work.

Does anybody know how to fix that ?

I finally solved this problem. First, i noticed that booting with acpi=off at grub worked. But it wasn't a good solution because my fan wasn't working well. So this is how i did :

At grub, add this 2 options :

• acpi=noirq

• acpi_iso=Linux ( needed if your fan stop working after using first option)

  • How do I add a kernel boot parameter?

Hope that it can help

Going into the BIOS settings and turning on my touchpad from there seemed to work for me. Beforehand, I had the EXACT experience you did during the install and post-install.

Once I changed, my keyboard worked without a problem.
