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 :)
