Recently Kernel 4.17 has been released. It has a major power consumption improvement so I decided to check it out now, before it is officially supported in Ubuntu 18.04.

There is a nice tool to do the upgrade on Ubuntu, it is called ukuu.

To install it just type:

1
2

$ sudo add-apt-repository ppa:teejee2008/ppa
$ sudo apt install ukuu

Then you are ready to go.

Ukuu has a nice graphical interface

All you need to do is choose the right version (4.17.2 in my case) and install it.

After reboot you should see the new kernel.

You can check it by typing

1
2

$ uname -r
4.17.2-041702-generic

The kernel seems to be very stable. I didn’t see any problems since the upgrade.

Have fun!
