[SOLVED] Can't change the brightness on OLED screens.

Post#1 by babam » 04 Sep 2021, 23:37

I have an Asus VivoBook X513EA Intel i3-1115G4 UHD Graphics and brightness can't be adjusted (it stays at 100%).

Code: Select all

sudo lspci -knn | grep -A6 VGA

0000:00:02.0 VGA compatible controller [0300]: Intel Corporation Device [8086:9a78] (rev 01)
	Subsystem: ASUSTeK Computer Inc. Device [1043:1432]
	Kernel driver in use: i915
	Kernel modules: i915
0000:00:04.0 Signal processing controller [1180]: Intel Corporation Device [8086:9a03] (rev 01)
	Subsystem: ASUSTeK Computer Inc. Device [1043:1432]
	Kernel driver in use: proc_thermal
	Kernel modules: processor_thermal_device
Update:
Deepin 20.2.2 and Linux Lite 5.6 are also unable to adjust the brightness.

Thanks.

Which DE? Try this (convert to xzm, put it inside modules folder and reboot).

And this can help on XFCE 5.0rc3:
Porteus-v5.0rc3 x86_64 bug reports
Porteus v5.01 KDE x86_64
