Brightness on HP Pavilion DV6
Hi,
Dual Booting System:
Windows 7
Xubuntu 12.04.3
Installed on HP Pavilion DV6 Laptop (Core i5 1st generation):
This Laptop has some issues/problems with 'Linux' only as the very same issues/problems don't exist with Windows 7Code:lshw hp-pavilion-dv6 description: Notebook product: HP Pavilion dv6 Notebook PC

1- Most of the time, I can NOT control the brightness level of my display/monitor (can not increase nor decreaase)
2- Some other time, I can but whenever I increase the brightness level, I can not change it after that neight to decrease it nor increase it
3- Whenever I reboot, the brightness level are not saved
4- I control the brightness level on F2 and F3 Keys on the Kebboard - with HP Pavilion DV6, you don't need to use Fn, just press either F2 or F3 to change brightness level. I don't know yet a way to change the brightness level from within the system (Xubuntu)?
You see, the brightness is a pain with this machine whenever I use Linux (Ubuntu based system).
On the very same machine, Windows 7 is installed (as purchased) and everything is working just fine but of course, I can't use Windows anymore, Linux in the blood now
Any idea how to solve this?
As mentioned earlier, this laptop is giving me hard time with 'Linux' only. So far, this is the 3rd issue (have some other different problems) but I'd like to fix these issues once and for all.
Thank you!
