Summary0008385: Kali i3 & xfce4-power-manager
Description

2hexed on Discord have brought this issue up to me, where upon closing the lid of their laptop (on Kali i3), xfce4-power-manager would create a popup error box saying "None of the screen lock tools ran successfully, the screen will not be locked".

I was able to replicate the issue on my Lenovo L540 using an fresh ISO image from https://cdn.arszilla.download/kali/kali-i3-amd64.iso

Upon some research, I've ran into this post: https://forum.xfce.org/viewtopic.php?id=14993 , I've asked him to run the following commands:

  • xfce4-power-manager-q && xfce4-power-manager --debug
  • cat $(which xflock4) | grep -A12 LOCK_CMD
  • xfconf-query -c xfce4-power-manager -p /xfce4-power-manager/logind-handle-lid-switch -n -t bool -s true

I've attached the output of the first 2 commands below. The first output file is similar to what I've got on my L540.

Upon running the last command above, it seems like it had fixed his issue, however I am trying to find the root cause of this issue to apply a fix (whether to the xfce4-power-manager package or i3-dotfiles). However, I could use some assistance on debugging this issue as its a bit out of my depth.

Steps To Reproduce
  1. Download the ISO from https://cdn.arszilla.download/kali/kali-i3-amd64.iso
  2. Prepare the ISO using Balena Etcher
  3. Install it on a laptop and reboot
  4. After installation, close the laptop lid
  5. Should have reproduced the error

In some further tests, I was unable to replicate this issue in Kali XFCE. However, I noticed this issue is present on my Dell XPS that has the same Kali i3 installation for 6+ months. It did not have this issue before, so I am a bit lost on how this issue came to be, but my theory is with the 2023-06-22 update (4.18.2.1). I tried downgrading to 4.18.1.1, but no luck/change in behavior...

If you can reproduce the issue, you should check what fails exactly. Looking at the code of xfce screensaver, we can see that the function that fails is xfce_screensaver_lock. This function is defined here: https://gitlab.xfce.org/xfce/libxfce4ui/-/blob/master/libxfce4ui/xfce-screensaver.c#L560

Looking at this function you can see that the logic is 3 steps:

  1. First, try to run a user-defined command, if any
  2. Otherwise, check if there's a well-known screensaver present on dbus, use it if any
  3. Finally, try some well-known commands, one after the other, and stop if ever one succeeds

For the i3 desktop, the screen locker is betterlock, right? Maybe you need to instruct xfce4-screensaver to use betterlock, maybe it's possible to do so in the xfce4 screensaver preferences?

So testing xfce4-screensaver, the error has disappeared. However, as soon as the lid is closed, Kali resorts to locking and displaying lightdm, instead of betterlockscreen (which uses i3lock-color). I am trying to figure out how can I invoke that, instead of whatever xfce4-screensaver and xfce4-power-manager is invoking, but no luck. Any ideas?

Small excerpt from https://gitlab.com/Arszilla/kali-i3/-/issues/10 :

Some more details, as I managed to squeeze in some time and diagnose the bug a bit further.

  • The bug/issue occurs as LockCommand is orphaned/undefined in $HOME/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-session.xml, since Kali i3 does not use XFCE4, but only its power-manager, as I couldn't find a better alternative back when.
  • This can be fixed by executing xfconf-query --create -c xfce4-session -p /general/LockCommand -t string -s &quot;/usr/bin/betterlockscreen -l&quot; and xfconf-query --create -c xfce4-session -p /shutdown/LockScreen -t bool -s true or by creating xfce4-session.xml with the following content:
&lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?>

&lt;channel name=&quot;xfce4-session&quot; version=&quot;1.0&quot;>
  &lt;property name=&quot;general&quot; type=&quot;empty&quot;>
    &lt;property name=&quot;FailsafeSessionName&quot; type=&quot;empty&quot;/>
    &lt;property name=&quot;LockCommand&quot; type=&quot;string&quot; value=&quot;/usr/bin/betterlockscreen -l&quot;/>
  &lt;/property>
  &lt;property name=&quot;shutdown&quot; type=&quot;empty&quot;>
    &lt;property name=&quot;LockScreen&quot; type=&quot;bool&quot; value=&quot;true&quot;/>
  &lt;/property>
&lt;/channel>

When the system is rebooted and Laptop Lid action is set to Lock Screen, this works flawlessly and fixes the issue. However, one thing I've seen in my testing is that if the action is set to Suspend, the system does suspend, but it does not lock the screen prior (or after, even though this would be a shit action to do) to suspending the laptop. This happens regardless if Lock screen when system is going to sleep in Security is enabled.

I'll be taking a further look and hope to diagnose this, maybe when I can wipe the laptop or get another laptop to test on, as I'd like to do my diagnosis on a clean system to ensure that there is no bloat, no-nonsense, etc.

As a result https://bugs.kali.org/view.php?id=8513 has been opened.

The changes have been reflected to i3-dotfiles and as a result, I am currently building a new ISO with the changes applied. I will try to test it ASAP but no ETA on it.

Additionally, https://gitlab.com/kalilinux/build-scripts/live-build-config/-/merge_requests/31 has been opened to reflect the changes required to the hook as per the dotfiles update.
