[BUG] Waypaper doesn’t retain wallpaper, and Rofi shows theme warning

[Firebleudark]

Describe the bug

Hi,

First, thanks a lot for your great work on this project!

I’ve been experiencing a persistent bug that I’d like to report so I can get some help.

System info :

• OS: Arch Linux (fully up to date)
• Dotfiles version: latest version from this repository

Issues

1. Waypaper starts automatically at every boot, and always asks me to choose a wallpaper — it never remembers my previous selection.
2. The wallpaper applies temporarily, but it resets on reboot.
3. When I change my theme using waybar, everything looks fine, but I get this warning from Rofi on startup:

The following warnings were detected when starting rofi:
Validating the theme failed: the variable 'current-image' in `mainbox { background-image: var(current-image); }` failed to resolve.

Steps to reproduce

Just launch Hyprland

Expected behavior

What I’m hoping for :

• Is there a way to make Waypaper remember the selected wallpaper?
• Should I disable its autostart? If so, how?
• Could the Rofi theme be made more robust by checking if current-image is defined before using it?

Thanks in advance for your help — and again, great work on this project!

@Firebleudark Did you run ml4w-hyprland-setup after updating?

[Firebleudark]

Yeah !

[Affanmm]

I FIXED the issue. SEE issue #938

[Firebleudark]

I tried your solution and it only works partially. The wallpaper selection application no longer launches at startup. However, I now have a black desktop background and I can't set my wallpaper anymore - the application simply doesn't work at all.

Can you send me your config.ini

[Firebleudark]

Yeah of course. This is my file without modification :

[Settings]
language = en
folder = ~/wallpaper
monitors = All
wallpaper = ~/wallpaper/astronaut_jellyfish.jpg
backend = hyprpaper
fill = fill
sort = name
color = #ffffff
subfolders = False
show_hidden = False
show_gifs_only = False
show_transition_options = True
post_command =
number_of_columns = 3
swww_transition_type = any
swww_transition_step = 90
swww_transition_angle = 0
swww_transition_duration = 2
swww_transition_fps = 60
use_xdg_state = False
show_path_in_tooltip = True
all_subfolders = False
mpvpaper_sound = False
mpvpaper_options =
zen_mode = False

language = en
folder = ~/wallpaper
monitors = All
wallpaper = ~/wallpaper/astronaut_jellyfish.jpg
backend = hyprpaper

show_hidden = False
show_gifs_only = False
show_transition_options = True
post_command =

use_xdg_state = False
show_path_in_tooltip = True
all_subfolders = False
mpvpaper_sound = False
mpvpaper_options =
zen_mode = False 

Try using post_command = $HOME/.config/hypr/scripts/wallpaper.sh "$wallpaper". This time variable is in double quotes. And after modification, open the terminal and run waypaer from it and send me the output. See if there is some error or something.

[Affanmm]

Try running ~/dotfiles/.config/hypr/scripts/wallpaper.sh ~/wallpaper/city_bridge.jpg in the terminal. See if it generates the colors properly and if the rofi error is still there.

[Firebleudark]

After the modifications, the error has indeed disappeared and the color for waybar has been properly modified. However, this was not the case for the terminal. And every time I restart my PC, I always get the same black background and I have to manually reset my wallpaper each time.

[Affanmm]

Try running ~/dotfiles/.config/hypr/scripts/wallpaper.sh ~/wallpaper/city_bridge.jpg in the terminal. See if it generates the colors properly and if the rofi error is still there.

Give me the output of this command.

Btw when I add this : post_command = $HOME/.config/hypr/scripts/wallpaper.sh "$wallpaper" in my config.ini file and I launch the wallpaper app I get errors : File "/usr/bin/waypaper", line 5, in <module> from waypaper.__main__ import run File "/usr/lib/python3.13/site-packages/waypaper/__main__.py", line 22, in <module> cf.read() ~~~~~~~^^ File "/usr/lib/python3.13/site-packages/waypaper/config.py", line 83, in read config.read(self.config_file, 'utf-8') ~~~~~~~~~~~^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.13/configparser.py", line 735, in read self._read(fp, filename) ~~~~~~~~~~^^^^^^^^^^^^^^ File "/usr/lib/python3.13/configparser.py", line 1050, in _read ParsingError._raise_all(self._read_inner(fp, fpname)) ~~~~~~~~~~~~~~~~^^^^^^^^^^^^ File "/usr/lib/python3.13/configparser.py", line 1079, in _read_inner self._handle_rest(st, line, fpname) ~~~~~~~~~~~~~~~~~^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.13/configparser.py", line 1105, in _handle_rest self._handle_header(st, mo.group('header'), fpname) if mo else self._handle_option(st, line, fpname) ~~~~~~~~~~~~~~~~~~~^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.13/configparser.py", line 1144, in _handle_option raise DuplicateOptionError(st.sectname, st.optname, fpname, st.lineno) configparser.DuplicateOptionError: While reading from PosixPath('/home/firebleu/.config/waypaper/config.ini') [line 27]: option 'post_command' in section 'Settings' already exists

It says that the post_command function is repeating. Make sure that there is only one post_command function in the config file and that will be the new line that i added.

[Affanmm]

Yeah of course. This is my file without modification :

[Settings]
language = en
folder = ~/wallpaper
monitors = All
wallpaper = ~/wallpaper/astronaut_jellyfish.jpg
backend = hyprpaper
fill = fill
sort = name
color = #ffffff
subfolders = False
show_hidden = False
show_gifs_only = False
show_transition_options = True
post_command =
number_of_columns = 3
swww_transition_type = any
swww_transition_step = 90
swww_transition_angle = 0
swww_transition_duration = 2
swww_transition_fps = 60
use_xdg_state = False
show_path_in_tooltip = True
all_subfolders = False
mpvpaper_sound = False
mpvpaper_options =
zen_mode = False 

make sure you remove the line that already says" post_command = " and replace it completely with new line.

[Firebleudark]

Oh yeah my bad ! Now everything is ok !
