[Bug 1247464] Re: Lenovo G700 - Screen gets dark after startup

  Thread Previous • Date Previous • • Thread Next 
** Changed in: linux (Ubuntu)
   Importance: Medium => Low

** Description changed:

- I have a lenovo g700-notebook. i installed ubuntu 13.10. on monday. It was very tricky. On startup with Ubuntu-Install-USB-Stick  after aprox. 30 secs. the screen got dark. I didn't know whats going on. so i tried starting several times. At least i mentioned that the brightness was at minimum (screen dark), but with the 'brightness+' (F12) i could see the screen. This behavior still remains, but now i know waht to do. Other users may have problems with this behavior. The brightness-key allows to darken the screen absolutely, so you dont see what happens. At least i'd like to save the screen-brightness, but i'm unable to do this. On startup the brightness is always on 'dark'-mode and i have to brighten up the screen.

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I have a lenovo g700-notebook. i installed ubuntu 13.10. on monday. It
  was very tricky. On startup with Ubuntu-Install-USB-Stick  after
  aprox. 30 secs. the screen got dark. I didn't know whats going on. so
  i tried starting several times. At least i mentioned that the
  brightness was at minimum (screen dark). The brightness-key allows to
  darken the screen absolutely, so you dont see what happens. At least
  i'd like to save the screen-brightness, but i'm unable to do this. On
  startup the brightness is always on 'dark'-mode and i have to brighten
  up the screen.
