MX Linux, Xfce 4.18

Closing the laptop lid suspends the system, opening it resumes it, but the screen is black. I’m guessing it’s related to powerup because suspending through the logout menu and systemctl suspend both work as expected. When it’s black, switching to a different tty works, as well as C-M-Backspace to logout.

Same results with both lightdm and sddm, when replacing suspend with hibernate, and I’ve tried a few solutions like disabling lock on sleep.

Seems like this issue has been around for years, but had a whole bunch of different causes since every other thread has a different solution.

XFSETTINGSD_DEBUG=1 xfsettingsd --replace --no-daemon > /tmp/xf.log 2>&1

ps -ef | grep -E ‘screen|lock’

xfconf-query -c xfce4-power-manager -lv

dmesg, cleared it before trying to suspend

updates:

I’m not seeing a black screen, instead it turns on the display and then turns it off.

Additionally, I tried closing and opening the lid a few times, and it woke up correctly.

I tried it in i3wm with the xfce power manager to suspend after closing the lid. It woke up correctly 10 times in a row.

Solution: start an xrandr config and the monitor turns back on.

    I’ve tried resuming 50+ times while troubleshooting, and it only once did it correctly. Now I try to replicate the bug and it worked correctly 2/3 times

    That’s just the computers fucking with you. It’s how it always happens 😉

    Regarding the sleep modes, I was referring to the S* states. Run this:

    dmesg | grep 'S3\|suspend'

      Tried systemctl suspend and then resume:

      dmesg after a successful resume

      sudo dmesg | grep -E "S3|suspend"

        The only thing that looks odd in there is the default in libgl, but otherwise looks okay. So it’s probably not a compatibility problem.

        How is your swap sized compared to your system memory?
