Comment 4 for bug 838181

Looks like you've got a 64-bit install, so you'll want to grab the two files ending in amd64.deb and the one ending in all.deb. Download these to a directory with no other files, then open a terminal, navigate to that directory, and run 'sudo dpkg -i *.deb'. When that finishes reboot, open a terminal, and run 'uname -a'. If you see lp838181v201109011442 in the output then you're running the right kernel for testing.
