[Bug 1250051] [NEW] Backlight switched off at login screen

 

Public bug reported:

Whenever I used to boot on ubuntu, my login screen was too dim, I
wouldn't know my computer was switched on until I increased the
brightness with my keyboard.

I asked for a solution on Ubuntu IRC, and the user hitsujiTMO managed to
create me a temporary solution that worked fine, and he recommended me
to file this report.

The temporary fix was calling
http://paste.ubuntu.com/6398879/
from the display manager

When I asked him if the problem was the same as this one: 
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/765438

He told me that, that's for a specific hardware  and told me to run
"lspci -nn"

Title:
  Backlight switched off at login screen

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Whenever I used to boot on ubuntu, my login screen was too dim, I
  wouldn't know my computer was switched on until I increased the
  brightness with my keyboard.

  I asked for a solution on Ubuntu IRC, and the user hitsujiTMO managed
  to create me a temporary solution that worked fine, and he recommended
  me to file this report.

  The temporary fix was calling
  http://paste.ubuntu.com/6398879/
  from the display manager

  When I asked him if the problem was the same as this one: 
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/765438

  He told me that, that's for a specific hardware  and told me to run
  "lspci -nn"
