Alright, buckle up your big boy pants because you are going balls deep today!
We get to play with the terminal. This guide is made assuming that you can get to the terminal [(edit) and the Desktop GUI.] Here is a list of commands that will set you up and upgrade your kernel.
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install software-properties-common
sudo apt-get update
sudo add-apt-repository ppa:teejee2008/ppa
sudo apt-get update
sudo apt-get install ukuu
sudo apt-get upgrade
- Now go ahead and use UKUU to update the kernel to 4.11.3
- It will say that there are errors the first time you try this, ignore
that.
- Reboot your computer.
- Go back to UKUU and reinstall 4.11.3 kernel
- If the install was successful, go ahead and restart your computer
again.
Now run
sudo apt-get purge ukuu
sudo apt-get update
sudo apt-get upgrade
If you only have access to the terminal use this advice given from Lemonslice
As a workaround, you might want to try to install 4.11 from the Ubuntu mainline kernels.
You can download and install from http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.11.4/ the following packages:
sudo dpkg --install linux-headers-4.11.4-041104_4.11.4-041104.201706071003_all.deb \
linux-headers-4.11.4-041104-generic_4.11.4-041104.201706071003_amd64.deb \
linux-image-4.11.4-041104-generic_4.11.4-041104.201706071003_amd64.deb
Now restart your computer when your kernel is installed and continue on.
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get -f install
sudo apt-get install gcc-6 g++-6
sudo apt-get update
sudo apt-get upgrade
- Now reboot your computer again for good measure.
When you computer has restarted go ahead and run
sudo apt-get autoremove
- Say yes to any prompts.
- Reboot your computer and now try your multimedia keys and possibly
your video drivers.
I have to do this for my laptop and desktop for it to fully function. The 4.11.3 kernel is really good and has not given me issues.
So yeah, it seems like a lot, but it is not. Have confidence!
edit: realized I made the assumption you could also get to the desktop to use the GUI. The answer from Lemonslice is the way to go. I believe it takes care of a nice chunk of legwork. I added it to my answer.
