backlight off when brightness under a certain level
Posted: 29 Apr 2013, 10:41
Hi all,
I have one issue on my Samsung Q310 using the voria tools, when I start the system using the battery the screen is off and I need to increase the brightness via the function key and the press fn+f5.
When I start the system with the AC power supply connected all is working good and the screen is in a visible state.
I guess that the issue is connected a problem appearing when reducing the brightness: I checked the file /sys/class/backlight/samsung/actual_brightness and it can go from 0 up to 8. When anyway I decrease the brightness under the 3 level, the screen backlight switches off completely and I cannot switch on again by increasing the brightness level. So the backlight is off even is the " actual_brightness" is more than 3.
1) is there a way to setup the initial brightness level when starting using the battery ?
2) Is there a way to set the minimum level to 3 instead of 0 ? This way I guess should fix all the issues.
Thx in advance.
