[Bug 568611] Re: Screen brightness control fails on Dell Studio 1558

[Triyambakesh]

At last the problem with LCD Screen brightness comes to an end.
I had the same problem with my Notebook Acer Aspire 5740, core i5 + Ubuntu 10.10 series
Now this got fixed permanently with adding the PPAs of Kamal Mostafa and Grub acpi_backlight=vendor.
All you need is to add PPA from Kamal's webpage https://launchpad.net/~kamalmostafa/+archive/linux-kamal-mjgbacklight and then go for modifying the grub parameters with "acpi_backlight=vendor". To do so please follow the instructions as per the webpage, strictly. Kindly see the post #78 for acpi_backlight=vendor.

I am sure for those with 'intelbacklight' this would be useful in
Maverick Series.

Thanx Kamal.
