XFCE Desktop Enviornment in Black Screen After Login (Screensaver)

Hi there, so whenever I relogin to my user account on Arch Linux, all I see is a black screen, this only happens when my Linux system idles, is there anyway to solve this?

Desktop Environment: Xfce(as you can tell by the title)
Display Manager:lightdm

What's your output in [ code ] [ /code ] tags without the spaces of

hostnamectl
loginctl session-status

Re: XFCE Desktop Enviornment in Black Screen After Login (Screensaver)

Please use [ code ] rather than [ quote ] tags.

You seem to have a session and a valid hostname what's your graphics hardware?

sudo journalctl -b #or maybe run a sudo journalctl -f and post the output generated from that when reproducing the issue

after logging back in?

Re: XFCE Desktop Enviornment in Black Screen After Login (Screensaver)

relogin

only happens when my Linux system idles

Does that mean when you unlock the screensaver after a S3 (sleep, suspend to ram)?
Try to disable the compositor: https://wiki.archlinux.org/index.php/Xf … te_manager

Re: XFCE Desktop Enviornment in Black Screen After Login (Screensaver)

Following @seth's query, if you are just unlocking the screensaver after it has triggered, your output shows you have xfce4-screensaver and xfce4-power-manager running.
You could try disabling one or the other as both together could be controlling the screen blanking at the same time?
xfce menu - "power manager - {display tab} - display power management" and move the slider to off.

Have you tried xscreensaver instead of xfce4-screensaver or just the xfce power manager on it's own?
