I have the same issue after the update to 2.6.27-11 Kernel. If I boot into 2.6.27-9 all is well, if I then boot into 2.6.27-11 no brightness control. Works perfectly well with older kernel, just not the new proposed update.
I am running an Acer Aspire 5920G so not HP specific either -- screen brightness control stopped working with 2.6.27-11 https://bugs.launchpad.net/bugs/315255 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
