Computer won't wake from sleep after suspend [xfce, debian testing]
Solution 1
Removing light-locker and using lightdm solved the problem for me on Debian 10.
$ sudo apt install lightdm
$ sudo apt remove light-locker
On Thinkpad T410.
Solution 2
If restarting LightDM after switching+log-in in the text console helps, then you can try this solution, found originally here: In the VT1 console, you can write this 1-line script:
while true; do DISPLAY=:0 xrandr --auto && break || sleep 1s; done
It will start looping. Then you switch to the GUI console (Ctl-Alt-F7), and in 1 second it should become active, with login prompt. If this works, we can create a fully automatic solution.

So, ever since I switched to xfce, I have been having some issues with suspending my system.
My system wakes from sleep normally most of the time, but every once in a while, my computer will turn on, and my status lights will turn on, but my screen won't initiate. I really have no idea why this happens, and it's been bothering me for too long.
I have a sneaking suspicion it has to do with xscreensaver. This is because I have disabled it, but I managed to wake my computer immediately one time and was greeted both to the lightdm login screen, then afterwards the xscreensaver login, which shouldn't be there.

Dávid Horváth almost 5 yearsI have similar problem. As a workaround, I press Ctrl+Alt+F1 then Ctrl+Alt+F7. After this, X11 session will be reactivated in a few seconds.

SpecialBomb almost 5 years@DávidHorváth ah, you posted this right after it started happening again. I guess its another bug? Ill try that next time.

SpecialBomb over 6 yearsThat didn't seem to work. I only had full power mode and ram power only mode, and I still had issues with either one of them.

EsmaeelE about 4 yearsI remove my previous comments, [see in history]. Installing either
xscreensaver
orxfce4-screensaver
instead oflight-locker
not solve this problem. I think something is wrong inlightdm
when want to turn on monitor. This solution completely disable any way of lock monitor. -

7heo.tk over 2 yearsThis worked for me on Devuan Beowulf (corresponding to Debian 10) running the default graphical stack (xfce4). I will now do a
recoverXsession
script to run in another VT when it gets stuck after sleeping for long. Thanks!
