Summary: Unwanted brightness events from ACPI video device on
Dell Vostro 1520
Product: Wayland
Version: unspecified
Hardware: All

Status: NEW
Severity: enhancement
Priority: medium
Component: libinput
Assignee: wayland-bugs@lists.freedesktop.org
Reporter: s...@robots.org.uk
On the Dell Vostro 1520, each event from the brightness up/down keys triggers
an event from two different keyboards:
# libinput-debug-events

'libinput debug-events' instead

The following hwdb entry tells libinput to ignore events from the unwanted
device:
libinput:name:Video Bus:dmi:*svnDellInc.:pnVostro1520:*
LIBINPUT_IGNORE_DEVICE=1
According to evtest, this device is capable of generating some other events:
# evtest /dev/input/event5
Input driver version is 1.0.1
Input device ID: bus 0x19 vendor 0x0 product 0x6 version 0x0
Input device name: "Video Bus"
Supported events:
Event type 0 (EV_SYN)
Event type 1 (EV_KEY)
Event code 224 (KEY_BRIGHTNESSDOWN)
Event code 225 (KEY_BRIGHTNESSUP)
Event code 227 (KEY_SWITCHVIDEOMODE)
Event code 241 (KEY_VIDEO_NEXT)
Event code 242 (KEY_VIDEO_PREV)
Event code 243 (KEY_BRIGHTNESS_CYCLE)
Event code 244 (KEY_BRIGHTNESS_ZERO)
Event code 245 (KEY_DISPLAY_OFF)
Fn+F8 generates KEY_SWITCHVIDEOMODE on the normal keyboard device, so this too
is redundant. The other events do not correspond to any key combination that I
know of, so it's probably safe to ignore this device entirely.
