Does this bug describe the same issue as bug #562005? The other bug seems to describe the issue as affecting a broader class of users, those with a particular family of Nvidia mobile chipsets, whereas this bug talk about a specific family of Dell laptops.
I experience this very issue on my Lenovo T510 with Nvidia NVS 3100M, which is what led me to this bug initially, and then 568005. -- 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
