You are not logged in.
Repo steps:
1. Log into Arch Linux (X11 / lightdm).
2. Power off monitor.
3. Wait a few seconds.
4. Power on monitor.
Expected:
User is logged into Arch.
Actual:
Display remains black. Continue:
5. Press Ctrl+Alt+F1 to open the console.
6. Press Alt+F2 to open a login prompt.
7. Log in.
8. Run:
sudo killall -9 lightdmAt this point, X11 automatically restarts and is usable again until the monitor is turned off.
Using latest nvidia-open driver.
I don't see anything suspicious in the logs, which I cleared out before performing the steps to crash X11 / lightdm.
Adding nomodeset to the boot parameters didn't help.
Is crashing X11 / lightdm after powering off the monitor a known problem?
Any ideas how to diagnose or fix the issue?
