This may be a network related issue. I experience the same issue at work 
in Windows 7. Depending on what development work I am doing I will leave 
my system active and screen locked when I go home at night. Our network 
is configured to disconnect inactive applications after, I think now, 25 
minutes, so when I get back into work in the morning and unlock the 
screen all the open windows have moved back to the primary screen. If I 
lock the screen and unlock it after say 5 minutes the same thing doesn't 
occur.

Steve

I know, or I think I know, that you're asking the question of me since it 
appears
after my response in the thread.  But, if someone isn't using or following 
threads
they would have no idea what this is in reference to.  It would be totally 
without
context.

But, to answer your question, of course it isn't going into suspend or 
hibernate. 
I'm a bit more observant and knowledgeable about how I have my system 
configured. 
:-) :-)

This does not happen for me on a desktop system with KDE and Xorg.

One thing that does happen is, if I manually power off the secondary monitor 
(which I
do since the HDMI in has a chromecast connected) and forget to power it on 
before
moving my mouse to wake up the monitors the secondary monitor will no be sensed 
by
the system and will remain dark.  However, the windows on the secondary monitor 
will
remain there.

In hibernate/suspend, the system essentially powers down. This is quite
different than a screen lock, where the system remains alive and kicking.

When it comes back up from hibernate or suspend, it's probably going to
initially see just the primary display and doesn't really know about the
second screen. How you'd get around that, I'm not sure. Sometimes even
USB and other external devices (e.g. E-SATA and the like) don't come up
from suspend/hibernate modes either.

I don't screen lock and very seldom 'suspend' or
'hibernate' the system.  But the few times I
did susp or hiber, I noticed the same behavior.
All windows came back in workspace one.

I tried the same experiment:
1. Dual screens
2. windows on secondary display and in several workspaces on the primary 
display.

3. locked the screen

When unlocked everything was where it was prior to locking.
Did I do that right?

You could always also look at podman as an alternative.  Should work
the same was as the Docker client, but not require you to run a
daemon.

   interesting ... a (very) cursory glance suggests podman has no
docker-related dependencies, but is based on CNI? so, just to be
clear, one could play with podman with no docker-related packages
installed? that seems worth looking into.

Yes podman mantra is #nobigfatdaemons, so it does not/should not require 
docker to be installed.

Dual screen

[Patrick Dupre]

Hello,

I noted a small issue when using dual screening (primary and secondary 
displays).
If you have windows open in different workspaces, they all move in
workspace 1 after a screen lock.
Is it a configuration issue or something else?

Let me add that I've tried also bluetoothctl.
I can pair it but after a few seconds it's disconnected:

I've now searched this error and found a possible solution here:
https://bbs.archlinux.org/viewtopic.php?id=180165

It says that installing bluez-hid2hci would solve the problem.
It was not installed on my system, so I'll give it a try when I'm 
back home.




I'm doing some progress. Now the bluetooth connection is kept and the 
speaker appears in the Sound settings (see attached screenshot).


But the speaker is mute. It might be some audio library missing or 
what?
I tried `dnf search a2dp` and found only package sbc, which is 
already installed.

Some problem with PulseAudio?




I disabled pulseaudio respawning and added verbosity (pulseaudio 
-vv)

and I got this interesting information:

I: [pulseaudio] module-suspend-on-idle.c: Sink 
alsa_output.pci-_00_1b.0.analog-stereo idle for too long, 
suspending ...


which brought me to the solution suggested here:
https://askubuntu.com/questions/218444/sound-output-starts-delayed

i.e. commenting load-module module-suspend-on-idle in 
/etc/pulse/default.pa


Now I can play music on that speaker. Success :-)

Sorry for this "solo thread", but I hope it can be helpful for others.

Best
Federico
