Ubuntu 13.10 ?

[xa.fr]

Seems to work fine for me.
Is there a chance of getting samsung-backlight in 13.10 and 14.04?

Well, any particular reason why you need samsung-backlight?

Actually, I've not even tried to use samsung-backlight (and easy-slow-down-manager) on ubuntu 13.10, because it's really old now and not updated in a while... I think samsung-laptop is way more reliable, it's actively maintained and shipped with the kernel by default, and it should provide the same (or even more) functionalities.

I have installed the latest samsung-tools from the ppa and a old version of samsung-backlight on my Samsung R519. Without samsung-backlight i cannot change the screen brightness.
Samsung-tools however fixes the fan control and disable/enable wlan card (Ubuntu returns an error when turning on/off the wlan card, but it works anyway).

Without samsung-backlight i can only change brightness when booting up or shutting down but not on a running Ubuntu.

I installed samsung-tools for 13.10 on my samsung series 9 NP900X3E but I could get the backlights to work. Most samsung-tools line commands I use end a timeout, something like this:

Code: Select all

Traceback (most recent call last):

    main()
  File "/usr/bin/samsung-tools", line 725, in main

I have installed this PPA on a Linux Mint 15. Backlight works with Fn-F5, Wireless works with Fn-F9 and other keys work too. Only the Fn+Up/Down arrows don't work to adjust brightness. The OSD for brightness comes up but the brightness does not actually change. The Fn+Right/Left arrows work fine to increase or decrease volume. The Fn+Up/Down arrow keys used to work fine for adjusting brightness in Linux Mint 14. Now I just use "sudo setpci -s 00:02.0 F4.B=2A" to adjust the brightness. Any help on why the Fn+UP/Down keys are not working?

You need to install samsung-backlight to get the arrow keys working.
Just use an old version. Unfortunately there are no new versions available...

Where did you get samsung-backlight from?

I installed the last version available from http://ppa.launchpad.net/voria/ppa/ubun ... backlight/ but it's still not wokring on my R510. Any suggestions?

Kind regards, haggis
