I just installed Ubuntu 12.04.2 64-bit on my desktop PC and I see the kernel in System Monitor is 3.5.0-23 but in Ubuntu 12.04.2 in my laptop the kernel is 3.2.0-38.
I have already tried to run the command sudo apt-get upgrade && sudo apt-get dist-upgrade
on my laptop but it doesn't update the kernel.
How can I upgrade kernel for my laptop?
