    Laptop screen dims to minimum settings upon boot

    Been a very long time since I've played with linux but have decided to get back into it!

    Have done my usual research and I'm finding a consistent result for fixing this issue of adding a line to /etc/rc.local

    The problem is the folder "rc.local" doesn't exist!

    I'm using Lubuntu 12.10

    Cheer's guys

    /etc/rc.local is a file, not a folder. Add the command to the end of the file above the existing "exit 0" command. You will need administrative rights to edit this file, so execute it as (from a terminal window):
    Code:
    gksu leafpad /etc/rc.local

    Sorry for the late reply, been pretty busy.

    Ok so I've got the file up using the command you gave me, a possibly silly quesiton: How do I enable that script? or rather what exactly is it I need to change?

    install xbacklight, then do command xbacklight when you have first set the screen brightness to what you want. After you see the number xbacklight gives you type command
    Code:
    xbacklight set -numberyouwanthere
    for example my command is
    Code:
    xbacklight -set 80
    finally in startup applications add xbacklight as name and xbacklight as command. Let me know if it works.

    Almost there!

    Installed xbacklight, and I've used the command you've given me to set it at the prefered brightness, I'm now just a little stuck as to adding it to the startup applications, I've done some googleing but I can't really find anything that helps me much.

    just go to Startup applications and type what I show in the screenshot except note the screenshot leaves off the last letter in the command should end in backlight

    Hey guys, sorry for yet another late reply

    The following is a screenshot of what I get in Lubuntu when I try to edit my startup applications, I can't find the same sort of edible "startup" section like you have used, I'm assuming that screenshot was taken in ubuntu rather than lubuntu?
