Ubuntu keeps more than one kernel on the hard drive. It defaults to using
the most current one.

You can choose which Linux kernel to boot from by using the GRUB menu on
booting.

To do that, switch your computer on, and, as soon as you see the
manufacturer's logo (i.e. the BIOS screen), press and hold down the
right-hand SHIFT key.

You should then see a menu with a title at the top that reads like "GNU
GRUB version" (etc). This is where you can do quite a few things. Use the
down arrow key to select "Advanced Options for Ubuntu". This takes you to a
screen where you choose a kernel to boot or choose to boot a particular
kernel in"recovery mode".

The command "uname -a" gives info on the current running kernel.

The command "lsb_release -a" gives distro-specific info.

HTH,

Ian
