I'm installing 13.04 (64 bit) from DVD on an Alienware M17x R4 laptop, dual-booting with Win 7.

Within the installer/live CD, both mouse and touchpad work. However, after installation when I boot into Ubuntu, neither mouse nor touchpad work - I'm stuck at the login screen. Ctrl+Alt+Fn doesn't drop me into a terminal either.

If I boot into Ubuntu recovery mode, I can get to the root shell etc and the keyboard works.

What I've tried:

  • dpkg option in Ubuntu recovery mode
  • chrooting into the install via the Live CD (probably could have used root shell in recovery mode) and running "apt-get update; apt-get upgrade"
  • Installed nvidia graphcis drivers.
  • Installed linux-image-extra-uname -r
  • Setting acpi=false, as well as i8042.reset in grub
  • Redownloaded & did another fresh install

Similar to this bug report: except that his recovery mode was broken and mine is not.

What would you recommend?

The problem was that I had leftover system directories from a previous linux install on the root partition. Deleting them and reinstalling 13.04 made everything work like a charm. Hopefully this helps someone!
