3 years ago Hey, I don't know if I relate to your exact problem, but take a look if the problem is lxqt-powermanagement or the lid detection event instead. I have a new laptop and my config does not work as expected. This project relies on upower notifying state changes. What I've been able to find is that the root of all problems is that the driver (probably kernel module "button") fails to notify the acpi event.
You can debug using upower --monitor-detail. Also, systemd-logind ignores handling configuration at /etc/systemd/logind.conf if some other application like lxqt-powermanagement takes a hold of the corresponding systemd inhibitor. So, assuming you have the lid watcher enabled you should see something like this when running systemd-inhibit:
WHO UID USER PID COMM WHAT WHY MODE
...
UPower 0 root 1088 upowerd sleep Pause device polling delay
lxqt-powermanager 1000 user 1380 lxqt-powermanag handle-hibernate-key lxqt-powermanager controls hibernate key block
lxqt-powermanager 1000 user 1380 lxqt-powermanag handle-power-key lxqt-powermanager controls power key block
lxqt-powermanager 1000 user 1380 lxqt-powermanag handle-suspend-key lxqt-powermanager controls suspend key block
lxqt-powermanagment 1000 user 1380 lxqt-powermanag handle-lid-switch LidWatcher is in da house! blockThe last line means that systemd-logind gives up control of lid state change handling to lxqt-powermanagement.
What to do if you have the same problem?
You can watch for the state of your lid with: cat /proc/acpi/button/lid/LID0/state. Polling lid state will:
- Assure you that is not a hardware problem (if you see it changes when you open/close your lid)
- If you poll it constantly, for some reason I don't understand, upower will notify of state changes, therefore lxqt-powermanagement will work as expected.
What I did:
/usr/local/bin/lid-watcher.sh
#!/bin/bash
while true; do
cat /proc/acpi/button/lid/LID0/state
sleep 2
doneThe above is just a script that polls for your lid state every 2 seconds.
$HOME/.config/autostart/lid-watcher.desktop
[Desktop Entry]
Exec=lid-watcher.sh
Name=lid-watcher
Type=Application
Version=1.0The above is the file you need to start the aforementioned script on lxqt session login (you can set it up from lxqt-config-session).
I hope this helps you or someone in the future.

Expected Behavior
Lid and idle watcher behavior should change when... they're changed
Current Behavior
I have to manually edit elogind configuration for it to work.
Possible Solution
I've got no clue. Could this maybe be expecting regular systemd-logind to be used, and tries changing it through systemd? If so, elogind support would be needed
Steps to Reproduce (for bugs)
Context
I wanted my configuration to have it suspend on lid close all the time except when connected to my monitor. In addition, I wanted to suspend after 20 minutes of idleness - mostly as a "band-aid fix" for the idle watcher still being enabled during video, which, by the way, is also something that I'd like changed.
