[Bug 1173961] Re: [Gateway NV55C] Two backlight interfaces that wont adjust backlight.

  Thread Previous • Date Previous • • Thread Next 
Max Oropeza, as per
http://support.gateway.com/us/en/product/default.aspx?tab=1&modelId=3265
an update is available for your BIOS (1.30). If you update to this, does
it change anything?

If not, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Thank you for your understanding.

** Description changed:

- I couldn't get the backlight to work after I upgraded to 13.04. I tried
- changing the grub parameters, and after several trys, nothing. I was
- asked to run     grep . /sys/class/backlight/*/* and got the results of:

- GRUB_CMDLINE_LINUX="acpi_osi="
- 
  But using the Fn Keys, you can only adjust it a little, like from full
  brightness to about half. To add something else, with the other
  parameters when I adjust with the Fn Keys, the brightness bubble you get
  on the top right of your screen doesn't appear.
