Today I tried 14.04 live from USB on an old LG (S1 Express Dual) laptop (Centrino Duo, 1 GB RAM) which never had any serious problems with Ubuntu since 6.10 however the keyboard isn't responding at all. Any suggestions are appreciated. Thanks.

Try attaching a USB keyboard. It seems that 14.04 has some unsolved issues with the "old" PS/2 keyboard and mouse controller (i8042).

That's a neat workaround. And it did work. Thank you.

I found an actual solution to my problem here (http://askubuntu.com/questions/276493/keyboard-not-working-on-lg-laptop/278817#278817?newreg=493c37a1e81d40b08942a6542b03b 453).

The steps are:

You need to edit the file /etc/default/grub

$ sudo gedit /etc/default/grub
Go to the line GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" and edit it to:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i8042.nopnp=1 i8042.dumbkbd=1"

Update grub

$ sudo update-grub
Reboot your computer.
