Re: Show us your conky

Hello, my friend, thank you very much for your help! 
Your found the error.

circlewriting
It was lines 397 cpu1 and 410 cpu2 of the Lua script.
In both cases, the y-value was changed from 220 to 210.
https://i.imgur.com/rtetZfWt.png

Your tip about not finding the "y-variable" clued me in.
I remember "adjusting" x and y variables for hours on a lot of the LUA scripts I've tweaked so it was an easy find.

Glad I could help.

I don't have the know how to write a LUA script, but given one I can bend fold and mutilate them into shape thanks to mrpeachy, RIP my friend, and falldowm, wherever you are, thanks.

Re: Show us your conky

@loutch

I really don't know why you use Conky to change the wallpaper at a specific time (Day/Night):
https://forums.bunsenlabs.org/viewtopic … 19#p145019

As I said, redshift always knows the exact time when day and night change at your location:
https://forums.bunsenlabs.org/viewtopic … 20#p145020

1) You need to install redshift  (not redshift-gtk):

$ sudo apt install redshift

2) Disable that conky (jour_nuit) at startup and redshift-gtk (if installed)

3) Add the redshift  (command) to startup

4) Open the ~/.config  folder and create a redshift.conf  file inside for your location (Sarreguemines - lat=49.110001; lon=7.070000):

; Global settings
[redshift]
temp-day=5840
temp-night=4480
transition=1
gamma=0.9
location-provider=manual
adjustment-method=vidmode

; The location provider and adjustment method settings
; are in their own sections.
[manual]
lat=49.110001
lon=7.070000

; In this example screen 1 is adjusted by vidmode. Note
; that the numbering starts from 0, so this is actually
; the second screen.
[vidmode]
screen=1

5) Open the /home/loutch/Images  folder and create a new wallpaper.sh  should look like this:

#!/bin/bash

## Day/Night Wallpaper - with RedShift ##

    sleep 8

    if [[ "$(redshift -p | grep 'Period' | awk '{print $2}')" == "Night" ]]; then
         
         xfconf-query -c xfce4-desktop -p /backdrop/screen0/monitoreDP1/workspace0/last-image -s /home/loutch/Images/Tahoe-Dark.jpg
         
      else
         
         xfconf-query -c xfce4-desktop -p /backdrop/screen0/monitoreDP1/workspace0/last-image -s /home/loutch/Images/Tahoe-Light.jpg         
         
    fi
 
  while sleep 2; do

  mode=$(redshift -p | grep 'Period' | awk '{print $2}')
  
  sleep 58
  
  mode_new=$(redshift -p | grep 'Period' | awk '{print $2}')
  
  if [[ "$mode_new" != $mode ]]; then   

    if [[ "$mode_new" == "Night" ]]; then
         
         xfconf-query -c xfce4-desktop -p /backdrop/screen0/monitoreDP1/workspace0/last-image -s /home/loutch/Images/Tahoe-Dark.jpg
         
      else
         
         xfconf-query -c xfce4-desktop -p /backdrop/screen0/monitoreDP1/workspace0/last-image -s /home/loutch/Images/Tahoe-Light.jpg         
         
    fi
  
  fi  
    
  done

6) Make the script executable

7) Add command  sh "/home/loutch/Images/wallpaper.sh"  to startup

Done.

LogOut/LogIn or Restart

Try and test with:

$ redshift -p | grep 'Period' | awk '{print $2}'

When the terminal output is Night,  the wallpaper will change in less than a minute.

You no longer have a fixed time (00:00 & 21:00) when Night/Day begins because redshift  knows the exact time (Sunrise/Sunset) for your location (Sarreguemines).

P.S.
Sorry, but I can't test.

Re: Show us your conky

Hello

Same problem like your other script in terminal, but it work , wallpaper is changed.

$ redshift -p | grep 'Period' | awk '{print $2}'
En attente de localisation...

Re: Show us your conky

^ Don't worry, that's the normal output for the 'redshift -p'  command:

$ redshift -p | grep 'Period' | awk '{print $2}'
Waiting for current location to become available...
Daytime

Now we wait for the night.
Turn on some AccuWeather Conky that has sunrise/sunset data.

Redshift works by gradually adjusting the screen to protect your eyes.
The Transition mode begins about half an hour before sunset.
The Night mode starts about half an hour after sunset.

Your night wallpaper should appear at that time in less than a minute.

Now that you have a redshift.conf  for your location (Sarreguemines), the wallpaper will always change about half an hour after sunset.
Here (in winter) the sun sometimes sets before 16:00, but the redshift  always does its job perfectly.

Check if this works in the terminal:

$ notify-send "Redshift" "Eyes protection changed" --icon=redshift

If it works, I will post a script that notifies you when it is Day / Transition / Night.
The Transition usually takes about 55 minutes because the redshift protects the eyes and gradually adjusts the desktop.

Re: Show us your conky

Sorry, @loutch.

I can't test wallpaper.sh  but I can test the redshift.conf  file.

$ redshift
Waiting for initial location to become available...
Location: 49.11 N, 7.07 E

This file ~/.config/redshift.conf  definitely works for your location:

; Global settings for redshift
[redshift]
; Set the day and night screen temperatures
temp-day=5840
temp-night=4480

; Enable/Disable a smooth transition between day and night
; 0 will cause a direct change from day to night screen temperature.
; 1 will gradually increase or decrease the screen temperature.
transition=1

; Set the screen brightness. Default is 1.0.
;brightness=0.9
; It is also possible to use different settings for day and night
; since version 1.8.
;brightness-day=0.7
;brightness-night=0.4
; Set the screen gamma (for all colors, or each color channel
; individually)
gamma=0.88
;gamma=0.8:0.7:0.8
; This can also be set individually for day and night since
; version 1.10.
;gamma-day=0.8:0.7:0.8
;gamma-night=0.6

; Set the location-provider: 'geoclue', 'geoclue2', 'manual'
; type 'redshift -l list' to see possible values.
; The location provider settings are in a different section.
location-provider=manual

; Set the adjustment-method: 'randr', 'vidmode'
; type 'redshift -m list' to see all possible values.
; 'randr' is the preferred method, 'vidmode' is an older API.
; but works in some cases when 'randr' does not.
; The adjustment method settings are in a different section.
adjustment-method=vidmode

; Configuration of the location-provider:
; type 'redshift -l PROVIDER:help' to see the settings.
; ex: 'redshift -l manual:help'
; Keep in mind that longitudes west of Greenwich (e.g. the Americas)
; are negative numbers.
[manual]
lat=49.110001
lon=7.070000

; Configuration of the adjustment-method
; type 'redshift -m METHOD:help' to see the settings.
; ex: 'redshift -m randr:help'
; In this example, randr is configured to adjust screen 1.
; Note that the numbering starts from 0, so this is actually the
; second screen. If this option is not specified, Redshift will try
; to adjust _all_ screens.
[randr]
screen=1

I apologize for the inconvenience, I should have checked earlier.
Now we wait again for the night to check wallpaper.sh.

Re: Show us your conky

Hello

I found 4 images from original macos tahoe

Made this  script

#!/bin/bash
# Kill if already running
if pidof -o %PPID -x "${0##*/}"; then
  exit 1
fi
# Start loop
while :
do
# What time is it?
  CURRENT_TIME=$(date +%H%M)
  if [ -n "$NEXT_TIME" ] && [ "$CURRENT_TIME" -lt "$NEXT_TIME" ]; then
    sleep 60
    continue
  fi
# Depending on time set WALL_CHOICE & NEXT_TIME
  if [ "$CURRENT_TIME" -ge 0500 ] && [ "$CURRENT_TIME" -lt 0659 ]; then
    WALL_CHOICE=/home/romuald/.conky/wallpaper/Tahoe/Dawn.png
    NEXT_TIME=0700
  elif [ "$CURRENT_TIME" -ge 0700 ] && [ "$CURRENT_TIME" -le 1959 ]; then
    WALL_CHOICE=/home/romuald/.conky/wallpaper/Tahoe/Day.png
    NEXT_TIME=2000
elif [ "$CURRENT_TIME" -ge 2000 ] && [ "$CURRENT_TIME" -le 2059 ]; then
    WALL_CHOICE=/home/romuald/.conky/wallpaper/Tahoe/Dusk.png
    NEXT_TIME=2100
elif [ "$CURRENT_TIME" -ge 2100 ] && [ "$CURRENT_TIME" -le 0459 ]; then
    WALL_CHOICE=/home/romuald/.conky/wallpaper/Tahoe/Night.png
    NEXT_TIME=0500
  fi
# Set the chosen wallpaper
  xfconf-query -c xfce4-desktop -p /backdrop/screen0/monitoreDP1/workspace0/last-image -s "$WALL_CHOICE"
# Sleep
  sleep 60
done

Work great on opening session & when i click at the script.sh but not when session is open since a few hours.

any idea??

Re: Show us your conky

any idea??

I didn't see that the post had been edited in the meantime.

I think these lines are wrong:

elif [ "$CURRENT_TIME" -ge 2100 ] && [ "$CURRENT_TIME" -le 0459 ]; then
    WALL_CHOICE=/home/romuald/.conky/wallpaper/Tahoe/Night.png
    NEXT_TIME=0500

The "$CURRENT_TIME" cannot be greater (or equal) than 2100 and less (or equal) than 0459 at the same time.

It might help if you use the OR (||) instead of the AND (&&) operator:

elif [ "$CURRENT_TIME" -ge 2100 ] || [ "$CURRENT_TIME" -le 0459 ]; then
    WALL_CHOICE=/home/romuald/.conky/wallpaper/Tahoe/Night.png
    NEXT_TIME=0500

It's probably better to specify a range between 0000 and 0500 at the beginning:

# Depending on time set WALL_CHOICE & NEXT_TIME
  if [ "$CURRENT_TIME" -ge 0000 ] && [ "$CURRENT_TIME" -lt 0500 ]; then
    WALL_CHOICE=/home/romuald/.conky/wallpaper/Tahoe/Night.png
    NEXT_TIME=0500
  elif [ "$CURRENT_TIME" -ge 0500 ] && [ "$CURRENT_TIME" -lt 0700 ]; then
    WALL_CHOICE=/home/romuald/.conky/wallpaper/Tahoe/Dawn.png
    NEXT_TIME=0700
  elif [ "$CURRENT_TIME" -ge 0700 ] && [ "$CURRENT_TIME" -lt 2000 ]; then
    WALL_CHOICE=/home/romuald/.conky/wallpaper/Tahoe/Day.png
    NEXT_TIME=2000
  elif [ "$CURRENT_TIME" -ge 2000 ] && [ "$CURRENT_TIME" -lt 2100 ]; then
    WALL_CHOICE=/home/romuald/.conky/wallpaper/Tahoe/Dusk.png
    NEXT_TIME=2100
  elif [ "$CURRENT_TIME" -ge 2100 ] && [ "$CURRENT_TIME" -le 2359 ]; then
    WALL_CHOICE=/home/romuald/.conky/wallpaper/Tahoe/Night.png
    NEXT_TIME=0000
  fi

Also check the username (romuald) and the path.
In the previous script:

WALL_CHOICE=/home/loutch/Images/ ...

Re: Show us your conky

@marens,

I need your help with awk again. 

lsb_release -d | cut -d '-' -f2
Description:	BunsenLabs GNU/Linux 13 (Carbon)

lsb_release -d | awk '{$1=""; print $5}'
(Carbon)

How do I get rid of the two brackets?

Edit: or

lsb_release -sirc
Bunsenlabs
13
carbon

?

Edit2: Found it, would you agree? 

lsb_release -sc
carbon

I am a fan of ‘brevity’ in Conky.

Thank you.

Re: Show us your conky

In my archives, I found a Conky that I had never tested before.
Here is the link and the original files.

Surprisingly, it worked pretty painlessly with LUA on Carbon. I had to change the syntax1.10;
the many ‘offsets’ for the pixel spacing (that shifts everything too often), it's much easier with ‘goto’     and I didn't have the image for the background either.
Marcello, my grandson, helped me out with Gimp. Great job!

--***********************************************************************************
--#
--#    Les fonctions à utiliser sont celle qui commence par "CCK_".
--#    Ce fichier est à inclure dans votre script lua (au début) comme cela: 
--#        dofile "leCheminAbsolu"
--#
--#    Utilisation:
--#        Il faut d'abord créer un CCE (Conky Cairo Element) grâce aux
--#        fonction CCK_jauge_Vertical, CCK_jauge_horizontal
--#        et CCK_disque.
--#        Puis on les dessines grâve aux fonctions CCK_dessine_jauge_Vertical,
--#        CCK_dessine_jauge_horizontal et CCK_dessine_disque.
--#
--#        Vous pouvez créer des couleurs grâce à la fonction CCK_couleur_rgba.

Re: Show us your conky

^ It looks very good on a light green background.
Your grandson is talented.

However, I must admit, I wasn't expecting the Ubuntu logo.
I thought the words Ubuntu and @unklar couldn't be in the same sentence. 

EDIT
I downloaded the image marco.png and played around a bit in the HOME folder using ImageMagick:

$ convert -define modulate:colorspace=HSB marco.png -modulate 100,100,200 test-red.png

$ convert -define modulate:colorspace=HSB marco.png -modulate 100,100,220 test-yellow.png

$ convert -define modulate:colorspace=HSB marco.png -modulate 100,100,120 test-blue.png

   

And of course gray:

$ convert marco.png -colorspace gray test-gray.png

Thanks to the grandson, you can now set a logo for any background.

Excellent!
All saved. Thank you very much. 

Your grandson is talented.

Oh yes, at ‘only’ 15 years old, he beats all the members of the family. We are very proud of him.

Correctly identified, you are a ‘fox’. 
However, I would like to emphasize(!) that *ubuntu* has the best wiki in the world(and, very good people).

Re: Show us your conky

However, I would like to emphasize(!) that *ubuntu* has the best wiki in the world(and, very good people).

People often forget or don't know that Ubuntu is based on Debian.
https://en.wikipedia.org/wiki/Ubuntu

Ubuntu is an ancient African word meaning ‘humanity to others’. It is often described as reminding us that ‘I am what I am because of who we all are’. We bring the spirit of Ubuntu to the world of computers and software.

https://ubuntu.com/about

I like this way of thinking.

It's true that I don't like the British company Canonical being involved in the project.
There have been some strange attempts in the past, but advanced users immediately issued a warning and it all ended with many apologies.

It is still free open source software.

Canonical belongs to the South African Mark Shuttleworth who founded Ubuntu, so it's hard to avoid their being "involved" in the project.

Re: Show us your conky

^ Yes, you're right.

For me:
Ubuntu = Canonical + Community

Companies are not charities and exist to make a profit.
As far as I know, Canonical is doing well, but it has to take care of the community.
The community is here to care about user privacy and to help Canonical developers with ideas, solutions, and advice.

So far everything seems fine.
