Long story shortened : "caffeine" is broken on my system so i went to launch "xfce4-power-manager"
to activate "presentation mode" to be able to watch full videos wthout the display turning off.
Went through a memory leak that affected "xorg" that ate up to 31% of available RAM.
Killed "xfce4-power-manager" and a few moments later, "xorg" was using 11% of available RAM.
5 minutes later, "xorg" was using 7% of available RAM.

Conclusion : "xfce4-power-manager" has most probably a very nasty bug in its code :bagoverhead: ...

Is there an alternative to the "caffeine" package ? I looked everywhere and couldn't find one...

What about turning off the "Display Power Management" (in "Display" tab in Power Manager) ?

(... Or set all items to "never" in both sub-tabs: When on battery / When Plugged in )

@Eadwine Rose : sorry for the inconvenience !
@Charlie Brown : I still need DPM to turn off the screen when the laptop is iddling...

ATM, Xorg is using 1.83% of the total RAM.

I uninstalled, reinstalled, purged "Caffeine", no matter what i try, it does not work anymore.
Just throwing this at the CLI :

Code: Select all

File "/usr/bin/caffeine-indicator", line 34, in <module> from Xlib import display

caffeine-indicator is a Python script, so you probably just need to add a dependency. I suspect a web search of the error message will provide a stackoverlow page outlining which Python package is needed. python3-xlib stands out as a possible culprit.

I turned on top, htop, xfce4-power-manager, and presentation mode and left a video playing on loop. After leaving it for two hours my laptop's CPU went up to 91C, but Xorg DRAM usage stayed about the same and actually dropped a little. Of course, I'm running Xfce on 16 GB of DRAM and not Blackbox on 4 GB, so that may be a factor.

Uninstalled "python3-xlib" then re-installed "caffeine" package with recommended dependencies.
This is the CLI output trying to run "Caffeine-indicator" :

Code: Select all

Traceback (most recent call last):
  File "/usr/bin/caffeine-indicator", line 34, in <module>
    from Xlib import display
  File "/usr/lib/python3/dist-packages/Xlib/display.py", line 26, in <module>
    from six import create_unbound_method
ImportError: cannot import name 'create_unbound_method' from 'six' (/usr/local/lib/python3.9/dist-packages/six.py)
And this is the CLI output after trying to run "caffeine" :

Code: Select all

Traceback (most recent call last):
  File "/usr/bin/caffeine", line 29, in <module>
    from ewmh import EWMH
  File "/usr/lib/python3/dist-packages/ewmh/__init__.py", line 3, in <module>
    from .ewmh import EWMH
  File "/usr/lib/python3/dist-packages/ewmh/ewmh.py", line 10, in <module>
    from Xlib import display, X, protocol
  File "/usr/lib/python3/dist-packages/Xlib/display.py", line 26, in <module>
    from six import create_unbound_method
ImportError: cannot import name 'create_unbound_method' from 'six' (/usr/local/lib/python3.9/dist-packages/six.py)
:bawling:
So, i've searched a little bit and found that : "The Python ImportError: cannot import name error occurs when an imported class is not accessible or is in a circular dependency."
9_9 Good to know. But i don't write Python code, so it won't help much in that case.

So, i've fired up "featherpad" and opened "/usr/local/lib/python3.9/dist-packages/six.py" to search for this string : "create_unbound_method".
I can confirm that it's nowhere to be found. There's no "create_unbound_method" in this file...

:snail: Going ahead to solve this exotic python mys(t)ery, i've found that :

Get defining class of unbound method object in Python 3
The concept of "unbound methods" has been removed from the language.
This was written in 2010. Almost 15 years ago.

The removal of unbound methods is documented here: http://docs.python.org/py3k/whatsnew/3.0.html#operators-and-special-methods

:needcoffee: I need caffeine.

Perhaps even something stronger : "caffeine-ng"
Caffeing-ng (since 2014) started as a fork of [Caffeine 2.4], since the original version dropped support for the systray icon in favour of only automatic detection of fullscreen apps only, which turned to be a rather controversial decision.

The intention of this fork is to also evolve on its own, not only fixing issues, but also implemented missing features, when relevant.

Caffeine-ng was shortly know as Taurine, a play on its successor's name, since taurine is a known stimulant, commonly found in energy drinks. However, this name did not last, since the artwork would not match adequately, and changing it was undesirable.
Riiiight ! Let's install it :

Code: Select all

sudo apt install meson \
    python-gi-dev \
    python-dbus-dev \
    libgtk-3-dev \
    libnotify-dev \
    libappindicator3-dev \
    python3-click \
    python3-ewmh \
    python3-setproctitle \
    python3-pulsectl \
    git \
    scdoc
Nope :
E: Unable to locate package python3-pulsectl
Damn it ! Let's remove "python3-pulsectl" from the packages list and try again :
The following packages have unmet dependencies:
libappindicator3-dev : Depends: libappindicator3-1 (= 0.4.92-8~mx21+1)
E: Unable to correct problems, you have held broken packages.
:rolleyes: Pffffff... No fun at all !

Okay, so, i've found that this line :

Code: Select all

# Stop X from blanking
xset dpms 0 0 0 && xset s noblank && xset s off && xset -dpms &
inside my startup script was conflicting with "xfce-power-manager" and causing "Xorg" to eat up so much RAM.
Now, to fix caffeine failure to run on my system, i've found that this script does the job efficiently. Workaround.
