Revision of Brightness in Trisquel-mini (lxde) for Samsung users from Tue, 12/10/2013 - 08:43
The revisions let you track differences between multiple versions of a post.
If the brightness keys (Fn+F2 and Fn+F3) don't work than you may tray this:
1) Installation of xfce4-power-manager package:
sudo apt-get install xfce4-power-manager
2) After this it must go in: /etc/xdg/lxsession/Trisquel-mini
and edit the file "autostart" and replace:
@gnome-power-manager
with:
@xfce4-power-manager
3) Edit grub:
sudo leafpad /etc/default/grub
change the line:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
to:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor"
save file
4) Update grub in terminal:
sudo update-grub2
sudo reboot
