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. -- Screen brightness control fails on Dell Studio 1558 https://bugs.launchpad.net/bugs/568611 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
