Same bug still exists. Am doing a fresh install of Saucy 13.10 on
Gateway NV79, but the install CD won't turn on the laptop display LCD
backlight. There is no way to provide further information since I cannot
directly install the 13.10 from CD image. Even if I attach an external
monitor, the
Additional information:
Once 13.10 is installed, it still boots to an off backlight; BUT I can use the
laptop screen brightness keys to increase backlight power and see the screen,
although it is somewhat washed out. Each time the laptop is restarted, however,
the setting is lost and it boots
Additional information 2: using the screen brightness keys only works
After SIGNING in, not before. closing and opening the laptop cover
(prior to signing in) also does not turn on the backlight, permantly. It
turns on briefly before ubuntu resumes after the suspend and then turns
off when unity
Additional information 3: work around for having backlight turned on after boot:
add the following to the grub: acpi_backlight=vendor

I have the same problem upgrading from 10.04 to 10.10 on my Gateway

working display.
