It doesn't happen every time, but often enough. The problem consists on xfce not coming back after a "wake up". All I get is a black screen (sometimes with backlight on, sometimes off). It's been happening for a while and I noticed it happens on many cases:
- when I suspend my computer (logind) by pressing the power button
- when I execute the command systemctl suspend
- when I lock my computer (lightDM)
I have no idea what is going on and what could cause such behavior.
Running journalctl -b -1 to get the last boot's journal logs, I get the following:
...

I've added a display-setup-script line on lightdm.conf to force it use the main monitor as default (at that point I thought the image was being shown on another monitor, since I use an external one), but no success. This was added to lightdm.conf:
display-setup-script=xrandr --output eDP1 --primaryBasically, I need help tracking the problem, since it doesn't follow any expected pattern and I can't reproduce it.
Thanks in advance!
#EDIT
Forgot to mention, but I am using Manjaro distro running xfce
