I believe this problem also affect Packard Bell EasyNote LV. It need i915.invert_brightness=1 to avoid the black screen of death when installing Ubuntu and when booting the installed system. With the setting in place, one can log into Gnome, but when one log into KDE, the screen is turned off again.
See http://www.linlap.com/packard_bell_easynote_lv for my notes about Linux on this machine. I've reported the problem to the kernel developers and as Debian bugs http://bugs.debian.org/710938 and http://bugs.debian.org/711237 . ** Bug watch added: Debian Bug tracker #710938 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=710938 ** Bug watch added: Debian Bug tracker #711237 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=711237 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/765438 Title: On startup, the backlight is off on laptop To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/765438/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
