Will do, but may be a bit later tonight. Gotta finish up work, then band practice. Long day.
Thanks

First one out of the gate worked
The first one I tried was GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux acpi_backlight=vendor"
That said, here is the other information you requested, maybe it will help you understand why it worked, so you can explain it to me
Code:myk@myk-Aspire:~$ cat /proc/cmdline BOOT_IMAGE=/boot/vmlinuz-3.8.0-23-generic.efi.signed root=UUID=3d62caab-2bac-40b9-891e-e79eb8afd3cb ro quiet splash acpi_osi=Linux acpi_backlight=vendor vt.handoff=7
Code:myk@myk-Aspire:~$ for i in /sys/class/backlight/*; do echo $i; cat $i/brightness; cat $i/max_brightness; done /sys/class/backlight/intel_backlight 96 976
Brightness hotkeys and slider are working. Thank you so much.Code:myk@myk-Aspire:~$ pastebinit /var/log/dmesg http://paste.ubuntu.com/5740645/

Perfect. Glad to hear.
I noticed, after the fact, that you had mispelled backlight in your post #2. That was the first option and it worked. So you were close.
acpi_osi=Linux tells the kernel to inform the bios that it is Linux so that it loads a certain set of acpi tables specific to Linux. acpi_backlight=vendor tells acpi to not use built in brightness management (acpi_video0), but to let the bios handle the brightness (in your case, intel_backlight).
Could you both please help me?
I have the same laptop Model (except that my intel generation is the second one), and I have tried the GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux acpi_backlight=vendor" but no luck. The other diference is that I use Kubuntu, I allready ask on their forums, but no luck
Please help
Can you confirm some information:
1. The version of kubuntu you are using.
2. Your current kernel boot parameter line:
3. Your video card and driver:Code:cat /proc/cmdline
4. Your backlight interfaces and their values:Code:lspci -k | grep -A3 VGA
5. Your dmesg log file:Code:for i in /sys/class/backlight/*; do echo $i; cat $i/brightness; cat $i/actual_brightness; cat $i/max_brightness; done
...and post back the link that is generated.Code:pastebinit /var/log/dmesg
6. Your Xorg log file:
...and post back the link that is generated.Code:pastebinit /var/log/Xorg.0.log
1. My version is Kubuntu 13.10 (same problem with 13.04) Kernel 3.11.0.12
2. cat /proc/cmdline
3. lspci -k | grep -A3 VGACode:BOOT_IMAGE=/boot/vmlinuz-3.11.0-12-generic root=UUID=0b573e08-fee6-43ca-af4c-2a98a22f5952 ro quiet splash acpi_osi=Linux acpi_backlight=vendor vt.handoff=7

Tanks for the reply
Can you try this:
1. Create the file /usr/share/X11/xorg.conf.d/20-intel.conf:
...enter your password when prompted.Code:sudo -i kate /usr/share/X11/xorg.conf.d/20-intel.conf
2. Copy/paste the following content:
3. Save the file.Code:Section "Device" Identifier "card0" Driver "intel" Option "Backlight" "intel_backlight" BusID "PCI:0:2:0" EndSection
4. Log out and back in again to see if it works.
If it still doesn't work, try removing the extra kernel parameters you added and trying again.

Glad to hear. Out of curiosity, did you remove the kernel parameters or are you still using them?
Yep I remove the parameters.
