GDM fades to black when closing

[Irkam]

Closing the window on Fedora 27 (Linux 4.15.6-300.fc27.x86_64) makes Gnome slowly fade to black, then lock the screen. Target device is a Nexus 6P on Android 7.1.2.

$ uname -sr
Linux 4.15.6-300.fc27.x86_64

$ gdm --version
GDM 3.26.2.1

$ scrcpy -v
scrcpy v1.0

dependencies:
 - SDL 2.0.7
 - libavcodec 57.89.100
 - libavformat 57.71.100
 - libavutil 55.58.100

This can be reproduced by running scrcpy and closing the window.

Wow.

Does scrcpy print something in the console in that case?

[Irkam]

Nothing out of the ordinary. This is my zsh output:

➜  ~ scrcpy 
/usr/local/share/scrcpy/scrcpy-server....shed. 2.9 MB/s (19038 bytes in 0.006s)
INFO: Initial texture: 1440x2560
➜  ~ 

Also:

➜  ~ gdm --version
GDM 3.26.2.1

Maybe related to #114.

In particular, this mail:

SDL sets a hint to disable the compositor for better performance and KWin honors this.

Maybe gdm handles that hint in a weird way.

Possibly related - closing the scrcpy window will crash my X Server entirely. Doesn't matter what desktop environment I'm using.

@danpozmanter Could you try with current master, please? I just fixed a bug that might explain the issue: 1a01393

@Irkam When scrcpy is running, could you post the result of the command:

ps xao pid,ppid,pgid,sid,comm | grep 'dm\|scrcpy'

[rom1v]

@Irkam Could you test the current master, please?

I guess it is fixed (#52 (comment)). If it is not, please reopen.
