Christopher, I reinstalled my Windows Vista from my restoration DVD just to check if brightness works and I had many difficult installing it. I was able to install an old XP and I discovered multiple errors about ACPI and the brightness control has issues on this OS too: I can see the brightness slider moving but the luminosity don't change. I need a reflow or a moterboard replacement. Seems Linux is enumerating periferals in a different way and is less sensible to hardware failures.
Please, mark this bug as invalid and close it. I'll contact you again if, after the hardware fix, the issue is still present. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1281176 Title: 8086:2a02 [Dell Vostro 1310] no brightness control on (x)ubuntu 13.10 / 14.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1281176/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
