Monitor not getting detected on suspend but is on resume
I'm trying to use ddcutil on a suspend script for systemd, as I did in other computers before, but the monitor is not getting detected when the computer is suspending, although it is when it resumes.
This is the script I'm running:
#!/bin/sh
if [ "${1}" == "pre" ]; then
ddcutil detect
ddcutil environment
ddcutil interrogate --verbose
ddcutil setvcp D6 05 --bus 11 --disable-capabilities-cache --disable-dynamic-sleep
elif [ "${1}" == "post" ]; then
ddcutil setvcp D6 01 --bus 11 --disable-capabilities-cache --disable-dynamic-sleep
fi
And this is the output of journalctl -b -u systemd-suspend.service
