Just noticed this is an Arrandale graphics card. Could well be just incomplete support for the card.
I think this needs to be re-tested against the Q4 Intel graphics release and then if it still happens there, forward it upstream. Stay tuned, we're still a week or two away from having that stuff packaged for testing. ** Summary changed: - Gateway NV79 Backlight and Monitor trouble + [Arrandale] Gateway NV79 Backlight and Monitor trouble -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/705949 Title: [Arrandale] Gateway NV79 Backlight and Monitor trouble -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
