 |
|
Hello,
I'm having problems setting up brightness keys (Fn+Home, Fn+End) on my Lenovo thinkpad X240.
When I hit Functional key and Home or End, it does not generate any acpi events.
(Only Fn+f1,f2 and f3 work. )
| Code: |
# acpi_listen
button/mute MUTE 00000080 00000000 K
button/volumedown VOLDN 00000080 00000000 K
button/volumeup VOLUP 00000080 00000000 K
|
I can't also change it by xbacklight because of following errors.
| Code: |
# xbacklight -set 10%
No protocol specified
RANDR Query Version returned error -1

In order to manage the backlight, CONFIG_BACKLIGHT_CLASS_DEVICE=y should give you a /sys/class/backlight directory with the controls inside. This appears to not happen on your system. Check dmesg why.
It may be that CONFIG_THINKPAD_ACPI_VIDEO competes with CONFIG_ACPI_VIDEO over control of the backlight device. |
