Bug ID: 112531
Summary: ASUS G752 Laptops don't handle all ACPI events
properly
Product: ACPI
Version: 2.5
Kernel Version: 4.4.1-2-ARCH
Hardware: All
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Config-Tables
Assignee: [email protected]
Reporter: [email protected]
Regression: No
Created attachment 203751
--> https://bugzilla.kernel.org/attachment.cgi?id=203751&action=edit
Includes boot entry for systemd-boot, output of dmesg, DSDT dat and dsl, EDID,
lshw output in text and HTML, lsmod output, lspci -vvv output, and uname -a
output
I am not entirely sure the OS can fix these problems, since it *might* be a
BIOS issue, but I am posting it here in hopes that it can be fixed by Linux,
since, same ACPI events work in Windows. Namely, the ACPI events for the
following combinations don't work:
- FN + F1: `XF86XK_Sleep`
- FN + F2: `XF86XK_WLAN`
- FN + F3: `XF86XK_KbdBrightnessDown`
- FN + F4: `XF86XK_KbdBrightnessUp`
- FN + F5: `XF86XK_MonBrightnessDown`
- FN + F6: `XF86XK_MonBrightnessUp`
- FN + F7: `XF86XK_Display` (Toggle laptop display on/off)
- FN + F9: `XF86XK_TouchpadToggle`
I'm not sure if I picked the right ACPi event for FN + F7, but on Windows it
definitely toggles the laptop's display on and off.
Also the G752 model has a set of "Macro" keys (http://i.imgur.com/LZDTr2B.jpg)
that also don't seem to work. Looking at `XF86XK_keysym`.h`, I think they would
correspond to these:
- Camera: `XF86XK_Launch0`
- M1: `XF86XK_Launch1`
- M2: `XF86XK_Launch2`
- M3: `XF86XK_Launch3`
- M4: `XF86XK_Launch4`
- M5: `XF86XK_Launch5`
I put `XF86XK_Launch0` rather than `XF86XK_WebCam`, because this does not
launch the webcam on Windows 10, but turns on screen recording instead.
For testing/debugging, I launched `acpid` and attempted to listen for events
with `acpi_listen`, but there was no visible output for any of the key
combinations mentioned above.
