Hello David,
I cannot create the file "${USER}-backlight" in /usr/local/share/ or I don't understand (maybe the "$" ?)
Thanks, regards,

andré,
"${USER}-backlight" will be a new file that holds the current brightness setting. ${USER} just expands to your username. It was just brace-enclosed to make that apparent.
For what it is worth I use the following script (with a second script that is just a wrapper to call the primary script with the -s option for startup) The wrapper script (scrnbrightwiznv_startup.sh) is simply:
#!/bin/bash
/home/david/scr/adm/scrnbrightwiznv.sh -s
In my ~/.kde/Autostart (you would have ~/.trinity/Autostart or ~/.tde/Autostart), I just use the symlink
l ~/.kde/Autostart/ ... scrnbrightwiznv_startup.sh -> /home/david/scr/adm/scrnbrightwiznv_startup.sh
The primary script is attached. You will need to change acpi_video0 to intel_backlight. Other than that, it should work for you. You can simply use the wrapper calling it with the -s option at startup in the Autostart folder if tdepowersave handles the changes during the session for you. (however, you will need a way to write the final brightness value to the file in /usr/local/ so it is saved for next startup.
There is no right way or wrong way to do this. Like I posted earlier, it can be display driver dependent, kernel dependent, distribution config dependent, etc.. Just find a way that works and stick with it :)
