Plasma Login Manager not Respecting Steam Set Session

[andy10115]

Plasma Login Managers seems like it's ignoring drop in overrides. I have to explicitly tell it to use the correct .conf by replacing the current contents of /usr/lib/steamos/steam-set-session with the following:

#!/bin/bash
set -e
DISPLAY_MANAGER="$(systemctl show -p Id --value display-manager)"
case "${DISPLAY_MANAGER%.service}" in
    plasmalogin) CONF_FILE="/etc/plasmalogin.conf";;
    sddm) CONF_FILE="/etc/sddm.conf.d/zz-steamos-autologin.conf";;
esac
# Don't do anything if system is using unsupported display manager
[[ -z "$CONF_FILE" ]] && exit 0
# Session, gamescope or plasma
SESSION="${1:-gamescope-session.desktop}"
if [[ ! -d "$(dirname "$CONF_FILE")" ]]; then
    mkdir -p "$(dirname "$CONF_FILE")"
fi
sed -i "s/^Session=.*/Session=$SESSION/" "$CONF_FILE"

Apologies I don't often write bug reports. It seems like KDE probably needs to fix this upstream, but as of right now at least on my current machine, it's not respecting the overrides the handheld package is pulling in.
