Posted: Sun Apr 01, 2018 4:44 am Post subject: [Solved] KDE Laptop Keyboard Backlight |
|
|
This notebook (Dell XPS 13) formerly had Arch on it and the latest KDE. What I liked about it is that KDE battery applet had control over the keyboard backlight in the latest version.
I recently installed Gentoo on it with the latest KDE (stable version) and the battery applet doesn't control the keyboard backlight.
Is there a way to enable this? Any ideas would be much appreciated.
Thanks.

You have configured CONFIG_DELL_SMBIOS and CONFIG_DELL_SMBIOS_WMI in your kernel?
Code: | $ grep CONFIG_DELL_SMBIOS /usr/src/linux/.config
CONFIG_DELL_SMBIOS=m
CONFIG_DELL_SMBIOS_WMI=m
# CONFIG_DELL_SMBIOS_SMM is not set |

No I haven't. Although, I don't have those options present in the config file. I'm using kernel 4.9.76-gentoo-r1.
EDIT: Nevermind, I found the options after enabling CONFIG_DCDBAS and CONFIG_ACPI_WMI. Enabling them now |

The options did not seem to enable the control. How can I change the brightness through the applet if I'm only able to change it via the button?
EDIT: I figured out I had to enable the CONFIG_DELL_LAPTOP option. To enable the control. Now it works thanks |
