ReGreet takes up to 30 seconds before showing up

[pescepalla]

I was a happy ReGreet user until yesterday morning, when it started acting up and now it drops me in a black screen for up to 30 seconds before the greeter shows up.

Here's my config:

$ cat /etc/greetd/config.toml
[terminal]
vt = 1

[default_session]
command = "cage -s -- regreet"
user = "greeter"

$ cat /etc/greetd/regreet.toml
[background]
path = "/usr/local/share/backgrounds/2560x1440-cityscape.jpg"
fit = "Cover"

[env]

[GTK]
application_prefer_dark_theme = true
cursor_theme_name = "Adwaita"
font_name = "Cantarell 20"
icon_theme_name = "Adwaita"
theme_name = "Adwaita"

[commands]
reboot = [ "off", "-r" ]
poweroff = [ "off", "" ]

And here's the output of journalctl:

$ journalctl -xeu greetd

For context, my setup uses polkit and I regret I need NVIDIA drivers. Launching regreet through sway instead of cage works.

$ uname -r
6.4.12-arch1-1

$ pacman -Q greetd
greetd 0.9.0-3

$ pacman -Q greetd-regreet
greetd-regreet 0.1.1-1

You mean ReGreet starts up fast if you're using Sway, and takes up to 30s when using Cage?

[pescepalla]

Yes. I've pinned it down to xdg-desktop-portal.

See https://github.com/flatpak/xdg-desktop-portal/issues/1115

When xdg-desktop-portal is uninstalled, I can use cage with regreet.

Solved upstream with release of xdg-desktop-portal 0.18.2
