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?

First I have heard of it tbh.  However, similar results when I have lost
power to a second screen.  Sounds like screen lock is losing connection
with the second screen.

hih,

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?

uname -r: 4.15.9-300.fc27.x86_64
gnome-session-3.26.1-1.fc27.x86_64

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.

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.

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.

Is there a possibility the system is going suspend/hibernate after screen
lock?  Thus, the disconnect?

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 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
