reMarkable 2 Framebuffer#
Changing the Device Backlight#
The reMarkable Paper Pro has a backlight that can be adjusted to make the screen easier to read in different lighting conditions.
Adjusting in the UI#
Xochitl provides 5 presets of backlight brightness, which can be accessed by swiping down from the top-right of the screen to open the quick settings menu
The Xochitl backlight presets are as follows:
260 (12%)
694 (32%)
1040 (50%)
1387 (67%)
1734 (84%)
Adjusting programmatically#
Setting the brightness outside of the range you can select in xochitl will make the battery drain faster, and may have unintended side effects that could damage the device.
The backlight can also be adjusted programmatically by writing to the /sys/class/backlight/backlight/brightness file. The value written to this file should be between 0 and 2047, where 0 is completely off and 2047 is the maximum brightness.
echo 1734 > /sys/class/backlight/backlight/brightness
