Issue

I am using a quit old pc. and it take some time to boot/ restart cinnamom.

It is very convenient to ignore this period, because in most PCs it should be very short, but i think it can be very confusing to see a black screen (when booting) or very strange screen (when restarting) without any explanation message- to explain what is going on.

Additionally, if I understood correctly, since Cinnamon 5.0 there is a memory limit that might cause cinnamon to restart- so it is very important to inform the user that cinnamon is restarting.

**Steps to reproduce & Expected behaviour **

Add a nice icon, a message or a progress animation- anything that inform the user what is going on.

A good example may be the LinuxMint icon when booting.

Is this kind of the idea you are thinking about? This is my Roku for example https://user-images.githubusercontent.com/24401303/137628867-fc6702bd-31cc-4a92-904a-8ddff205d4d6.MOV

Yes, something like that can be good.

Hi,
Recently, i encounter the GNOME's solution for the exact issue i opened:

More details: GNOME shell 40.5 Xorg on Linux Mint 20.2.
When restarting the DE (through SHIFT+F2 and then entering r).

In my opinion, this is a good and beautiful example for the solution,
but, as I already written in the issue beginning, I think an "Starting" message should be as well (not only when restarting).
