Bug ID: 84101
Summary: Brightness interface shown in desktop computer with
Intel graphics i915
Product: ACPI
Version: 2.5
Kernel Version: 3.16.1
Hardware: All
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Power-Video
Assignee: [email protected]
Reporter: [email protected]
Regression: No
For some reason the kernel detects an `acpi_video0` in /sys/class/backlight
even though it is running in a desktop computer whose monitors don't support
editing backlight levels on software.
`/sys/class/backlight/acpi_video0/device` is a symlink to the integrated
graphic card, listed on `lspci` as the following:
00:02.0 VGA compatible controller: Intel Corporation Xeon E3-1200 v2/3rd Gen
Core processor Graphics Controller (rev 09)
