Hi Brendan,

Can’t we instead patch ‘scripts/xflock4’ so that it refers to ‘xset’ by
its absolute file name?

However, my understanding is that the xset code is already a fallback:

--8<---------------cut here---------------start------------->8---
# else run another access locking utility, if installed
for lock_cmd in \
  "xlock -mode blank" \
  "slock"
  do
    set -- $lock_cmd
    if command -v -- $1 >/dev/null 2>&1; then
        $lock_cmd >/dev/null 2>&1 &
	# turn off display backlight:
	xset dpms force off
        exit
    fi
done
--8<---------------cut here---------------end--------------->8---

Probably we should ensure the first ‘for’ loop works as expected.
Perhaps we need to replace ‘xfce4-screensaver-command’ by its absolute
file name there.

WDYT?

Thanks,
Ludo’.
