Title:
OLED X1 yoga lenove, screen ubuntu, brightness issue
Status in linux package in Ubuntu:
Incomplete
Bug description:
As with all the proceeding distros from ubuntu 16.10 the brightness of the
OLED screen canot be set. Since xrander is no more present there is also no
hack around this problem anymore. This bug is a killer for using the system as
full brightness drains the battery quickly.
OLED screens have no backlight, thus this might be the issue.
