[SOLVED]scroll lock

W1F3B34T3R · 2020-04-19 14:21:03

My keyboard's rgb lighting works when i press the scroll lock button but i can't use that feature in arch so i made a bash script which lets me use scroll lock, but the problem is that i don't want to execute it every time i log into my computer, i have tried using the auto start feature in kde plasma but that doesn't works in the way i want. Even after executing the bash file after i log into my system it still looses it's functionality after half an hour or something around that. Here's the code i'm using right now

xmodmap -e 'add mod3 =Scroll_Lock'

.

Put an executable script in ~/.config/plasma-workspace/env/

it still looses it's functionality after half an hour or something around that

Sound like the keyboard gets re-attached (eg. for a power save or layout change) - afaics you'd have to deviate a custom layout or run the script periodically.

i just did that, but it didn't do anything. I still had to manually run the script to activate the scroll lock key.

Did what precisely?
What do script and/or custom layout look like and did you ensure it's (still) loaded?
(For the script, you could add some "echo foo > /tmp/bar" to track whether it ran)

Use Scroll Lock to turn on/off Keyboard Backlight

Finally, I have got the exact solution after suffering and trying many methods for 2 years. This method works on XFCE system without any problem. For other DEs, try and see if it works.

Install numlockx:
Ubuntu / Debian / Mint:

sudo apt install numlockx

Fedora / RHEL:

sudo dnf install numlockx

Arch / Manjaro:

sudo pacman -S numlockx

Paste the script:

cd /usr/local/bin/

sudo nano toggle_led.sh

#!/bin/bash
if xset q | grep -q "Scroll Lock: off"; then
    xset led named "Scroll Lock"
    numlockx on
else
    xset -led named "Scroll Lock"
    numlockx on
fi

Bind Keyboard Shortcut:
- Goto Keyboard
- Add
```
/usr/local/bin/toggle_led.sh
```
- Press Scroll Lock
- Keep the Startup Notification turned off.
Log out & Relogin your session.

Now, pressing the Scroll Lock will turn on/off the keyboard light.

Extra Note: numlockx is required to keep the numpad working after executing

xset led

command. If you don't have numpad in your keyboard, you can skip the Step-1 and also remove the

numlockx on

lines from the script.
