use the keyboard to change brightness.

i don't seem to have that option. My laptop has a brightness key with only 3 positions: too bright, too bright,and too dim. Not sure if that key does anything in Porteus, will try.

Ok. Use the above command as root to change the file permissions then save the file into your rootcopy folder to overwrite all other layers.

Code: Select all

cp -a --parents /sys/class/backlight/intel_backlight/max_brightness /mnt/sdXy/porteus/rootcopy

After that guest should be able to write to the file without needing sudo.

looked into this a bit further:
your /etc/sudoers.d/brightness should work if you use this command:

Code: Select all

$ echo 9000000 | sudo tee /sys/class/backlight/intel_backlight/brightness

from here: https://www.linuxquestions.org/question ... ost5720420
my test:

Code: Select all

# visudo -f /etc/sudoers.d/test
ALL ALL=(ALL) NOPASSWD: /bin/tee /root/test
:x
$echo 100 | sudo tee /root/test
100
#cat /root/test
100

i noticed i can run the power applet without running the power manager.
so i get brightness slider, just for the price of running the panel applet.
not bad!

change the file permissions if you want guest to write to it.
Code: Select all
chmod 666 /sys/class/backlight/intel_backlight/brightness

Great! That worked. tho it would be cool to solve the sudoers issue.

Ed, here's a brightness slider i made that doesn't depend on any background services like Power Manager. Works for me on Porteus 32-bit desktop.

It needs yad, which you can download and convert from here.
http://archive.ubuntu.com/ubuntu/pool/universe/y/yad/

And the user needs write-permission on the brightness file.

Code: Select all

chmod 666 /sys/class/backlight/intel_backlight/brightness

cheers!

Interesting. And thanks.

You can get yad from Porteus's USM.

Code: Select all

guest@porteus:~$ su
Password: 
root@porteus:/home/guest# usm -i yad

 The following items were found.
 Choose an number to confirm. 
 ctrl+c to quit

1) yad-0.40.0-x86_64-1_slonly.txz
2) phpmyadmin-4.8.2-noarch-1_slonly.txz
3) yadifa-2.2.4-x86_64-1_slonly.txz
#?

But why can't the user use the keyboard's Alt+F12 or Alt+F11 to raise or lower the brightness of their screen?

ALT-F11 and ALT-F12 seem to affect my Porteus panel and windows. Seems to set z-order or focus or something.

I found yad in the USM. But before downloading, i updated all the repos. Now it no longer comes up in USM search! And i'm getting:

Code: Select all

root@porteus:/home/guest# usm -i yad
find: `/tmp/xdg-runtime-guest/gvfs': Permission denied
 Nothing found for:  yad

Hrm....

I don't have that problem.
