 |
|
Hello,
I have an Acer E5 15. It's a silvermont arch and I am having backlight key and functionality issues.
The Kepcap and operations are backwards. When using the keycaps and autodimming it goes brighter rather than darker. It's weird.
Does anyone have any input?
Thank you.

hello,
does this help ?
https://wiki.archlinux.org/title/Acer_Aspire_E5-575#Function_keys
To add functionality for brightness keys, Fn+Left and Fn+Right, append the following parameters to your kernel boot line:
| Code: | | acpi_osi=Linux acpi_backlight=vendor |

acpi_backlight=vendor made the keys stop working all together.
cpi_osi=Linux exhibits the same with reversed auto dimming and they brighten key is on the left dim key is on the right. but the visual bar is backwards on screen but moves in the right direction. |
