    Knoppix 7.4.2 dazzles using uefi.

    .
    I've seen the light with uefi, but it's too bright for me.

    I have two Dell Inspiron laptops: One is a Win7 Model 1545 with Legacy boot,
    the other a Win8 Model 3520 with uefi boot.

    A Knoppix 7.4.2 LiveUSB with reiserfs persistence developed on the 1545 works
    as well on the 3520 with one peculiar exception. The backlight on the 3520 is
    uncomfortably bright.

    My first attempt to correct this situation was to add a line in /etc/rc.local
    commanding 'sudo /usr/bin/xbacklight 60' which works at a command line. But
    it doesn't work at rc.local. Apparently /etc/rc.local does not apply after
    all other init processes are done, after all.

    I recall that it was convenient to use /etc/X11/Xsession.d/45knoppix as a
    vehicle to remedy other things that rc.local no longer cured. So I've located
    my xbacklight command in 45knoppix as well, and it serves the purpose.

    So, I offer this Knoppix work-around if Win8 illumination is just too bright
    to accept.

    Just adding the line:

    @xbacklight = 30 [or more or less]

    in:
    /.config/lxsession/LXDE/autostart

    would not do?

    Greetings, Philo.

    Thanks for the nice alternative. As you point out,
    ~/.config/lxsession/LXDE/@autostart -set 60
    does the same thing as the 45knoppix workaround.

    I have in mind adding a little bash line that decides whether
    I want the Win7 or the Win8 machine to get this workaround.
    I think 45knoppix may make it easier to pull that off,
    unless you've got more magic to show us.
