Bug ID: 60657
Summary: Regression: backlight brightness not changeable with
fn keys
Product: ACPI
Version: 2.5
Kernel Version: 3.11-rc3
Hardware: All
OS: Linux
Tree: Mainline
Status: NEW
Severity: high
Priority: P1
Component: Power-Video
Assignee: [email protected]
Reporter: [email protected]
Regression: No
The fn brightness keys of my Laptop (HP 625) are not working anymore
since kernel version 3.11-rc1.
With older kernels of the 3.10 branch they are working fine.
Setting the brightness manually with
"echo number > /sys/class/backlight/acpi_video0/brightness"
works though.
I have tried adding "acpi_backlight=vendor" as a kernel parameter
but this did not fix it.
Do you need any more information?
Please let me know if this is the case.
