Dear Kamal, Could you please also look at Bug #538256 ?
It's the exact same issue but for Lenovo IdeaPad net/notebooks including Z360. Your kernel PPA works but only in GNOME. I use Ubuntu Maverick 10.10 + KDE 4.6.0 from KDE PPA and brightness control doesn't work at all. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/568611 Title: Screen brightness control fails on Dell Studio 1558 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
