Actually the problem is HAL. The Brightness author asked me to debug it for him and he concluded that HAL is not built with --with-dell- backlight option. If it was, the libsmbios package would have been automatically included in Feisty's ISO. So I am not sure what separate file I should file and what for.
I also tried Feisty on another laptop, a LinuxCertified.com laptop, and the Brightness applet does not work there either. -- 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
