Some Ubuntu laptops screen brightness reset to the lowest or highest on every boot and you have to configure the screen birghtness on every login.
To save the screen brightness settings in Ubuntu laptop.
Open a terminal window, and execute this command to edit /etc/rc.local:
sudo nano /etc/rc.local
Add this before the last line “exit 0″:
echo 5 > /sys/class/backlight/acpi_video0/brightness
number 5 is the value of your screen brightness. With this command check the maximum:
cat /sys/class/backlight/acpi_video0/max_brightness
Solution 2
My m6700 use the disk from another PC, which has xubuntu 12.04.
I had the same problem then I downloaded the kernel from
http://kernel.ubuntu.com/git-repos/ubuntu/ubuntu-precise.git
and compiled using the command:
fakeroot make-kpkg --revision 00.m6700 --initrd --append-to-version=-localmod kernel-image kernel-headers
and then installed the generated packages by the command dpkg -i *.deb
, then after a reboot the problem was solved.
The Git branch I checkout out was:
- Commit 35fd156f210074f981de9963ecd07fb3630e072d
