** Changed in: xscreensaver (Ubuntu)
Status: New => Opinion
** Description changed:
+ EDIT: Now if it is generally so that when you lock by xscreensaver
+ before suspending, suspending happens only after fading has completed, I
+ withdraw this bug report.
+
Steps to reproduce
1. Run 'xscreensaver-demo -prefs', activate the daemon, if requested
2. Ensure that "Fade to Black when Blanking" is set up with some non-zero
duration.
3. in terminal, run
xscreensaver-command -lock </dev/null && paplay
/usr/share/sounds/freedesktop/stereo/bell.oga
Result: The bell sound is played immediately.
Expected: play the sound after blanking is ready
This is regression from (X)ubuntu 18.04, i.e. xscreensaver 5.36-1ubuntu1.
I found a workaround that seems to work at least in Xubuntu 20.04 with
certain hardware:
In step 3, run
xscreensaver-command -lock </dev/null && xset dpms force off && paplay
/usr/share/sounds/freedesktop/stereo/bell.oga
In that xset command finished only after xscreensaver has finished
fading to black.
On another hardware this works, too:
xscreensaver-command -lock </dev/null && xset q >/dev/null && paplay
/usr/share/sounds/freedesktop/stereo/bell.oga
