Power manager does not grab any keys when started via xdg autostart

LividFruit · 2021-05-05 10:49:36

I just installed Xfce on Arch and I can't get brightness keys to work properly. They do work as expected (change of brightness plus notification) when I start xfce4-power-manager from an interactive shell, but not when power manager is started via xdg autostart.

In Session Manager, I disable the provided startup entry for power manager, and make a new one:

xfce4-power-manager --debug

Here's the output of xorg.log right after xfce is started:

By now, the brightness keys don't work. I then quit power manager and start it from an interactive shell. As shown in the output, power manager successfully grabs the keys and the brightness keys do work:

What kind of sorcery is this?!

Sorcery for sure. This makes no sense...unless some sort of race condition?

As a first step, can you try clearing your sessions cache? Delete the contents of ~/.cache/sessions while not logged in.

LividFruit · 2021-05-05 11:17:20

Done, same results.

How do you log into Xfce?

Do you use a display manager? and if so, which one?
Do you use xinit/startx? If so, can you post your ~/.xinitrc file?

Do you use a display manager? and if so, which one?
Do you use xinit/startx? If so, can you post your ~/.xinitrc file?

No display manager. startx is run when I log in and I've copied the default /etc/X11/xinit/xinitrc to my ~/.xinitrc (I followed this guide: https://wiki.archlinux.org/title/Xinit) and only added the last line:

#!/bin/sh

userresources=$HOME/.Xresources
usermodmap=$HOME/.Xmodmap
sysresources=/etc/X11/xinit/.Xresources
sysmodmap=/etc/X11/xinit/.Xmodmap

# merge in defaults and keymaps

if [ -f $sysresources ]; then







    xrdb -merge $sysresources

fi

if [ -f $sysmodmap ]; then
    xmodmap $sysmodmap
fi

if [ -f "$userresources" ]; then







    xrdb -merge "$userresources"

fi

if [ -f "$usermodmap" ]; then
    xmodmap "$usermodmap"
fi

# start some nice programs

if [ -d /etc/X11/xinit/xinitrc.d ] ; then
 for f in /etc/X11/xinit/xinitrc.d/?*.sh ; do
  [ -x "$f" ] && . "$f"
 done
 unset f
fi


exec startxfce4

And here's my ~/.xserverrc (also taken from the same guide mentioned above):

#!/bin/sh

exec /usr/bin/Xorg -nolisten tcp -nolisten local "$@" vt$XDG_VTNR

And startx is run from ~/.bash_profile :

startx -- -keeptty &> ~/.xorg.log

I believe this is somehow related to the dbus-update-activation-environment error that you are getting.

Can you try renaming your ~/.xserverrc file and commenting out the "startx" command in ~/.bash_profile? Then reboot, log in and run "startx". See if that makes the dbus-update-activation-environment succeed. If so, you can try to narrow down the cause by re-enabling each of those one at a time.

That particular dbus-update-activation-environment message no longer appears, with or without my ~/.xserverrc... I don't know if deleting ~/.cache/sessions/ once more had anything to do with that?? Anyway, without my ~/.xserverrc the xorg.log still looks pretty similar to the previous one:

Sorcery for sure. This makes no sense...unless some sort of race condition?

By race condition, are you hinting at the abrupt end of the debugging messages when power manager is started via xdg autostart? Again, when I start power manager, all looks good here:

...
TRACE[xfpm-power.c:930] xfpm_power_get_power_devices(): Power device detected at : /org/freedesktop/UPower/devices/line_power_AC
TRACE[xfpm-power.c:889] xfpm_power_add_device(): 'line-power' device added

TRACE[xfpm-button.c:180] xfpm_button_xevent_key(): Grabbed key 124 : ((XfpmButtonKey) BUTTON_POWER_OFF)
...

but when it's started via xdg autostart the TRACE messages end abruptly at the middle of a string:

...
TRACE[xfpm-power.c:930] xfpm_power_get_power_devices(): Power device detected at : /org/freedesktop/UPower/devices/line_power_AC
TRACE[xfpm-power.c:889] xfpm_power_add_device(): 'line-power' device added
TRACE[xfpm-power.c:930] xfpm_power_get_power_devices(): Power device detected at : /org/freedeskt 
##NO MORE TRACE AFTER ABOVE MESSAGE
...

Then power manager continues to print (non-debug) warning messages as shown in my first post.

To rule out a race condition, in your ~/.xinitrc file, put a "sleep 5" command before "startxfce4". Lets see if giving the system more time to perform startup routines helps.

This is definitely a strange one.

LividFruit · 2021-05-07 11:03:19

Ok done. Got the same output. I felt adventurous and grabbed the sources from the latest commit , built and installed but that didn't help. What next?

Sorry but I'm out of ideas. You can create a bug report here and see where it goes.

Will do, thanks anyway for your quick replies and suggestions!
