Make screen brightness settings stick

[bra|10n]

#!/bin/bash

ksystraycmd --startonshow --keeprunning --tooltip "Adjust Screen" --icon application-pgp-signature ~/.screen_brightness.sh

Above is a small script which you can make executable and add to autostart. It will place an icon in your sys_tray on startup by which you can toggle on/off your existing script (which for this purpose I have referred to as ".screen_brightness.sh"), and I have assumed lives in your home folder. (note the . (hidden file)). Names and file locations of course can be changed to your liking

But only add the above script to autostart as this script will then call your script as required.
Why your script needs root privileges to function I really don't know. If it is owned by you, and not root, does it still function? I can't imagine screenbrightness settings needing elevated privileges TBH.

But i'm not a bash expert by any means. Perhaps others might be able to offer some advice on this?

Thanks! I'll give that system-tray script a go. Does the screen_brightness.sh need to be hidden for some special reason? (Right now, it isn't, but I can certainly do that.)

The existing script is owned by me and executable by me. When I try to run it without permissions I get this error:

pcilib: Cannot open /sys/bus/pci/devices/0000:00:02.0/config

Please check the contents of /etc/pm/sleep.d/ for files relating to resume/wake.
Check any files with a text editor and *hopefully* you will recognize some code.
Here is the contents of 1 file here,

#!/bin/sh
#
# 90alsa: suspend/wakeup ALSA devices

case "$1" in
hibernate|suspend)
;;
thaw|resume)
aplay -d 1 /dev/zero
;;
*) exit $NA
;;
esac

I wonder if your script can't be incorporated into this one or called from this alternatively?
