I've seen posts like these but they all seem to mention the inability to get the brightness back up. I can turn the brightness back up with my keyboard, but it's an annoyance that I'd like to get rid of if at all possible.

After new install with Ubuntu 11.10 in HP G6-1229 Laptop I had the same problem. This was the best solution for me

After the install the LCD was black after boot. What you need to do is edit /etc/default/grub with you facorite text editor, ie:

sudo gedit /etc/default/grub

And change the line

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

with

GRUB_CMDLINE_LINUX_DEFAULT="quiet acpi_osi=Linux acpi_backlight=vendor splash"

Then update grub with

sudo update-grub

and restart the notebook.

Use your Fn (function) key with F3 (brightness raiser) to restore brightness to your display.

It's just at zero brightness. Increase the Brightness and it's all solved.

On my /etc/default/grub file, the line:

GRUB_CMDLINE_LINUX_DEFAULT="quiet acpi_osi=Linux acpi_backlight=vendor splash"

Did work perfect for me too, the only drawback i had to perform the first installation with no backlight. I'm using an hp (hp folio 13-1000) with the integrated intel chipset.
