Install another kernel?

Solution 1:

How can I install such a kernel?

If you supply the package version etc it should install that version

sudo apt-get install linux-image-3.13.0-24-generic

If for some reason you want to install loads of kernel, note that if you have a /boot partition, or a small root one you will likely run out of disk space, so the system won't boot.

Also, if you want to use a particular driver which only works with a certain kernel version, please make a question relevant to this

What command should I give in the terminal to start a kernel?

Kernels are the base part of system, so generally you need to reboot to change what is running at the core (probably not with linux kernel 4+ on some OSs with some updates though).

So change which kernel you are using you can reboot and show GRUB, then you can select to use the kernel - (The nearest command is sudo reboot which will reboot the system). By default it will choose the latest one (usually recomended for security stuff)
