Hi Ineedaname, thanks for the new topic  ;).  Okay lets try this.  First lets confirm you're using an intel graphics card.  Open a terminal window with the following keystrokes: Ctrl+Alt+t.  Enter the following command in the terminal window and hit enter:
Code: [Select]
ls /sys/class/backlight/You should receive an output something similar to this:
Code: [Select]
$ ls /sys/class/backlight/
acpi_video0  intel_backlight
If it is confirmed that you're using an Intel graphics card, proceed by entering the following command to create a new file:
Code: [Select]
sudo touch /usr/share/X11/xorg.conf.d/20-intel.confHit enter and enter your user password when asked.  Now we're going to open this file with the following command:
Code: [Select]
sudo gedit /usr/share/X11/xorg.conf.d/20-intel.confNow populate the empty file by copying and pasting the following text:
Code: [Select]
Section "Device"
        Identifier  "card0"
        Driver      "intel"
        Option      "Backlight"  "intel_backlight"
        BusID       "PCI:0:2:0"
EndSection
Save the file and exit gedit.  Logout of your current session of Peppermint and log back in.  Hopefully, you should now have backlighting and have screen brightness control too ;).

I see you don't have an intel graphics card.  Sorry, I don't know how to proceed with an NVIDIA card  :(.  Someone else may have a solution for you - good luck  ;)!!

It's ok :) the thing we can at least say we tried -  in due time everything eventually get's fixed and plus without that example snippet you posted

Code: [Select]
Section "Device"
        Identifier  "card0"
        Driver      "intel"
        Option      "Backlight"  "intel_backlight"
        BusID       "PCI:0:2:0"
EndSection

I actually wouldn't have been able to start looking for a fix and yes I'll post it once i find it  :D
