> How do you start your session and the portal?

I start wayfire by running a script manually in a TTY after I log in. It sets some environment variables; you can see it in the collapsed section below.

<details>
<summary>startwayfire.sh</summary>

```shell
#!/bin/bash

# Functionality variables
# if $XDG_DATA_DIRS is not set, set it to the spec recommended value
[ -z "$XDG_DATA_DIRS" ] && export XDG_DATA_DIRS="/usr/local/share:/usr/share"
# path for wf-config and wlroots
export LD_LIBRARY_PATH=/usr/lib/wayfire
# path is needed for wf-shell clients
PATH=$PATH
# path to find .desktop files like wcm
export XDG_DATA_DIRS=$XDG_DATA_DIRS
# maybe necessary?
export XDG_SESSION_TYPE=wayland
export XDG_CURRENT_DESKTOP=sway

# Display scaling
export GDK_DPI_SCALE=1.4
export QT_SCALE_FACTOR=1.4
export QT_FONT_DPI=96
export XCURSOR_SIZE=36
export XCURSOR_THEME=capitaine-cursors

# Theming
export QT_QPA_PLATFORM=wayland-egl
export QT_QPA_PLATFORMTHEME=qt5ct
export SDL_VIDEODRIVER=wayland

# Application variables
export MOZ_ENABLE_WAYLAND=1

# Logging
if [ -d "$XDG_DATA_HOME" ]; then
    DEFAULT_LOG_DIR=$XDG_DATA_HOME/wayfire
else
    DEFAULT_LOG_DIR=$HOME/.local/share/wayfire
fi
mkdir -p $DEFAULT_LOG_DIR

# Running
if [ $? != 0 ]; then
    echo "Could not create log directory $DEFAULT_LOG_DIR"
    echo "Using stdout as log"
    #wayfire
    #exec dbus-launch --exit-with-session wayfire
    exec dbus-run-session /usr/bin/wayfire
else
    LOG_FILE=$DEFAULT_LOG_DIR/wayfire.log
    if [ -f $LOG_FILE ]; then
        cp $LOG_FILE $LOG_FILE.old
    fi
    echo "Using log file: $LOG_FILE"
    #wayfire &> $LOG_FILE
    exec dbus-run-session /usr/bin/wayfire &> $LOG_FILE
fi
```

</details>

As for the portal, I start it through wayfire's autostart plugin. I have the following line in the `[autostart]` section of `wayfire.ini`: `portal = /usr/libexec/xdg-desktop-portal`
