some simple scripts to invoke steam as a separate user for non-robust filesystem isolation

invoke.sh

#!/bin/bash -x

if [[ -z "$XTXAUTH" ]]; then
    echo "XTXAUTH not set, was this invoked correctly?"
    exit 1
fi

unset XAUTHORITY
server=$( echo "$XTXAUTH" | awk '{ print $1 }' )
xauth add $XTXAUTH
export DISPLAY=$XTDISPLAY
unset XTDISPLAY XTXAUTH
eval $( pax11publish -i )
# xterm -bg black -fg white &
"$@"
wait
xauth remove "$server"

runassteam.sh

#!/bin/bash -x

for p in /run/user/$UID{,/pulse}; do
    chmod o+x "$p"
done
exec sudo XTXAUTH="$( xauth list | head -n 1 )" XTDISPLAY=$DISPLAY -i -u steam bin/invoke "$@"
