Support for dell backlights was integrated since hal-0.5.9.rc1, but ubuntu uses hal-0.5.8.
I tried to recompile 0.5.9.rc1 in my ubuntu, but the current patches (of 0.5.8) failed to apply and the binaries I got do not work with the gnome-power-manager. :( I agree with Eugenia, Feisty should backport the support for dell backlights but it is not as easy as I tought. -- HAL is not built with libsmbios https://launchpad.net/bugs/92194 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
