---

Waking up my laptop from suspend, the whole gnome session and Xwayland crashed. After that gdm3 prompted me to login again. This is the first time this happened to me.

(It's nice that even crashing it did it gracefully letting me log in again.)

Video showing the problem: https://youtu.be/TYMBOmLgPHI
The exact same thing happens 30% of the times I close/open the lid of my laptop.

Steps:

1. I am logged in and use Firefox, Byobu and a few other desktop applications
2. Time to go back home, I close the lid of the laptop
3. At home, I reopen the lid
4. Instead of just being asked for a password, I am being asked to choose a user. I started the video after seeing this, so this step is shown at 00:00
5. I click on my user, type my password and press Enter (00:14)
6. Purple screen (00:15)
7. Desktop shown very quickly (00:24) Not all icons are shown on the right bar, maybe those that I had left open are missing?
8. Screen goes pitch black immediately, like a kind of sleeping (00:25)
9. Nothing happens. Seems like the laptop is really in a kind of sleeping state.
10. Losing patience, I press the Escape key of my keyboard (00:52)
11. I am asked for my password (00:54)
12. I type my password and hit the Enter key (01:05)
13. My desktop shows up, all of my open applications are gone. Sadness. (01:07)

As others have said in the numerous duplicates, I am not using Wayland, but rather the out-of-the-box 2018.04.

Interestingly, when I reopen Byobu, my Byobu sessions are still alive. Byobu is designed to survive without X. Unfortunately, my VirtualBox virtual machines and LibreOffice always get killed violently, which makes work difficult.

Don't hesitate to ask me for any detail or log. I can reproduce the problem easily.
