Hi, I can’t seem to find a way to change the power settings for when my laptop is on battery or plugged in. When I have it plugged in, the screen goes dim, but when I have it on battery alone, the screen brightens up. I would like to be able to have it bright when plugged in like it is when on battery alone. Where do I find the config file to edit to make changes to the power settings? Also, based on my system info below, do I have the right kernel for my system? Thanks in advance! Here’s my system info:

Hi, similar topic was already discussed elsewhere.
See e.g.
https://www.antixforum.com/forums/topic/laptop-amd-cpu-low-battery-warning/#post-70389
Not 100% sure that the recommended package does what you desire.Also, there are two Debian packages that can help to manage power consumption in notebooks but they may turn off some ports if not used for some time.
I mentioned them in another topic but I need to leave soon and I do not have time to search for it.CyberGhost
@sybok, I already read that thread before. Xfce power manager didn’t change anything. Tried that. Also, the main topic on that thread you linked is about wanting to know when there is a low battery and how to make it notify you. I want to know how to keep the screen as bright when it’s on battery alone, for when it’s plugged in too. When plugged in, the screen goes dim a bit. So there has to be some configuration file that I can edit to make that happen.

Hi, I did the following web search ‘icewm power manager’ and it pointed me to ‘xscreensaver’, see the link
https://hrclinux.blogspot.com/2013/05/icewm-startup-commands.html
I have it installed and it has 3 options: Standby/Suspend/Off After.If not installed and hence not controlling the screen, then ‘antiX control centre’ -> ‘Session’ -> ‘Set Screen Blanking’ allows to control a single parameter.
Exploring what script does the job might point you to a configuration file with more options similar to ‘xscreensaver’.
The title of the pop-up window is ‘set-screen-blank’ which is a valid terminal command.
‘which set-screen-blank’ outputs ‘/usr/local/bin/set-screen-blank’, a shell script that does the job.It invokes ‘xset’ which I have discovered in another link
https://www.linuxquestions.org/questions/debian-26/screen-dims-and-shuts-off-constantly-4175492340/
See ‘man xset’ and search for ‘dpms’.I knew my first reply was not completely what you searched but I hoped that Xfce power manager could do the job.
I hope that the content of my current post is more on-topic this time.CyberGhost
@sybok Thanks that just might work! I’ll look into it. Also, it’s ok I know you’re just trying to help best you can and I greatly appreciate your help! I will do a little experimenting and report back.

Ok I read those articles from the links you posted @sybok but they didn’t help me. I did however find this from just looking around in the file system. I don’t know what, if anything in this file, can be changed or how to do it.

Just a thought: I have a laptop that has entries in the BIOS regarding that issue. Maybe yours has such a setting? (Brightness on battery & brightness when connected to power.)
confirmed antiX frugaler, since 2019

Also here’s a screenshot of possible options to edit.

@christophe Thanks I didn’t even think of that! I’ll check now!

@christophe Unfortunately, my BIOS doesn’t have that option

Have you looked at xrandr?

xrandr | grep " connected" | cut -f1 -d " "eDP-1
Change brightness to 50%
xrandr --output eDP-1 --brightness 0.5Change brightness to 100%
xrandr --output eDP-1 --brightness 1.0CyberGhost
@BobC Thanks I’ll try that!
More internet searching shows, to show current brightness:
xrandr --prop --verbose | grep -A10 " connected" | grep "Brightness"grep -A10 ” connected’ tells it to return the ” connected” line and 10 lines after it
sybok
@BobC: @Robin mentioned that ‘xrandr’ adds a “mask” that hides the brightness and is therefore not a power-saving solution (though it may reduce eye strain), see the following:
https://www.antixforum.com/forums/topic/display-brightness/page/2/#post-75656antiX contains a command ‘backlight-brightness’ (‘which backlight-brightness’ leads to ‘/usr/local/bin/backlight-brightness’).
It did not work for me for some reason, same output as in https://www.antixforum.com/forums/topic/display-brightness/#post-73166
I remember that @masinick mentioned elsewhere this might be related to kernel.sybok, thanks for that warning.
I tried xbacklight on mine, and it says “no outputs have a backlight property”
In addition, the Brighten and Dim keys on my keyboard have no effect under Linux. Not sure if that is just antiX or all, as I usually run antiX on this machine.
