Crashing on launch - python: No such file or directory

[jathanasiou]

I have installed nebula on Manjaro 4.14 kernel with lgogdownloader v3.2.2 to avoid login issues, however I had the same behaviour occur with 3.3 as well.
Upon launching the /opt/games_nebula/games_nebula.py file with python2 or calling the start.sh script I get the below output and the program exits:

Traceback (most recent call last):
  File "/opt/games_nebula/games_nebula.py", line 6931, in <module>
    sys.exit(main())
  File "/opt/games_nebula/games_nebula.py", line 6927, in main
    app = GUI()
  File "/opt/games_nebula/games_nebula.py", line 125, in __init__
    self.get_monitors()
  File "/opt/games_nebula/games_nebula.py", line 6567, in get_monitors
    proc = subprocess.Popen(['xrandr'],stdout=subprocess.PIPE)
  File "/usr/lib/python2.7/subprocess.py", line 390, in __init__
    errread, errwrite)
  File "/usr/lib/python2.7/subprocess.py", line 1025, in _execute_child
    raise child_exception
OSError: [Errno 2] No such file or directory

All of the required and optional dependencies for Archlinux appear to be properly installed via pacman/AUR.

'Games Nebula' use xrandr. You most likely using Wayland not X11, so xrandr not installed on your system. You have to install xorg-xrandr and (probably) xorg-server-xwayland if it's not installed.

I'm running Cinnamon and I feel rather confident I'm on X.

[yancharkin]

Anyway you need xrandr, error indicates that it's not installed.

[jathanasiou]

It appears that xorg-xrandr resolves the issue. If that is required however it probably needs to be added to the dependencies of the AUR package, right?

[yancharkin]

Looks like it. It's just strange. Usually xrandr installed automatically when using X11. Also I'm not maintaining AUR package.
