I'm getting the message: "The system is running in low graphics mode. Your screen, graphics card and input device settings could not be detected correctly. You will need to configure these yourself." ...

... but only during shutdown.

It doesn't impact use in any way, but it's confusing to people who see it while the machine is shutting down.

The system is NOT running in low graphics mode - it's working perfectly and at the correct (high) resolution.

How can I prevent this message from showing for 5 seconds every single time I reboot or shut down? The message ONLY appears during shutdown.

Graphics: i915.

Yes, I have a SSD. I've already put the sleep 2 in my /etc/init/lightdm.conf.

Your problem seems to stand at LightDM, so probably you can fix that by these steps:

sudo apt-get update
sudo apt-get upgrade
sudo dpkg-reconfigure unity-greeter
sudo dpkg-reconfigure lightdm

Select "lightdm" and test it, if it didn't solve the problem try running the last command again and choosing a different option (if there is one).

If you is still having trouble try:

sudo gedit /etc/lightdm/lightdm.conf

and replace the following line:

greeter-session=pantheon-greeter

by:

greeter-session=unity-greeter

If it not be effective replace back the line to its previous state.

I face the same error. At that time you just need to go into tty mode and and login with user id and password. After that run the following command.

sudo apt-get dselect-upgrade

It will solve your problem.
