This solves Debian Bug report 1008760:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1008760.
Solution was inspired by this kernel bug report message:
https://bugzilla.kernel.org/show_bug.cgi?id=204967#c15.
My measured pad dimensions with a ruler were 85x44mm.
But I decided to take the 2x size reported by the current kernel
when invoking the touchpad-edge-detector command from the
libdev-tools package. Because this comment claims that the old
vs new kernel reportings differ by factor 2:
https://bugzilla.kernel.org/show_bug.cgi?id=204967#c3 .
Therefore I have used this command to get the new entry to 60-evdev.hwdb:
"root@pb:~# touchpad-edge-detector 80x34 /dev/input/event2
Touchpad ETPS/2 Elantech Touchpad on /dev/input/event2
Move one finger around the touchpad to detect the actual edges
Kernel says: x [0..1254], y [0..528]
Touchpad sends: x [0..2472], y [-524..528] -^C
Touchpad size as listed by the kernel: 40x17mm
User-specified touchpad size: 80x34mm
Calculated ranges: 2472/1052
Suggested udev rule:

It appears that exceptional layout of legacy device requires extra care of
hwdb entry for node device since Linux FireWire subsystem do not pick up
numeric model identifier in vendor directory. In detail, see:
* https://github.com/systemd/systemd/issues/25029
In the case, udev rule without model attribute is used. Thus hwdb entry
for generic AV/C device should match both cases with and without the
attribute. The wildcard added by a commit 5e577da5f8 ("hwdb: drop model
specifier from general entries") satisfies this condition,
This commit adds comment about it.
It appeared that Sony DCR-TRV310 has legacy layout of configuration ROM
against 1394 TA standard documentation.
* https://github.com/systemd/systemd/issues/25029
For the case, numeric model identifier and descriptor leaf for model name
are not picked up. This commit fulfill corresponding entry so that
applications can use model name from hardware database.
Add new key mappings for the HP Elite Dragonfly G2 laptop:
1. Map Fn+F12 (HP Programmable Key) to prog1.
2. Unmap Fn+F11 (Airplane mode) from atkbd and Intel HID events, as this
key is also reported by HP Wireless hotkeys.
* Add special keyboard combos for Thinkpad P1 Gen 3
These are based on the key codes I've found with evtest. See issue
https://github.com/systemd/systemd/issues/24814 for more details.
I'm not entirely sure what some of these keys are supposed to do,
notably Fn+RShift; this doesn't seem to do anything in Windows on
my machine. Binding them to prog# makes them available to desktop
managers' key bindings at least, in case someone wishes to make
use of this extra keybind possibility.
As usual, it seems to be mostly additions and corrections. Sadly, it seems a
bit of mojibake has crept in in various places. But it's hard to correct, in
particular because it's hard to detect all cases automatically. I think we can
ignore this for now.
When I run this a few weeks ago, ma-large.txt was gutted and 20-OUI.hwdb was
siginificantly smaller. For whatever reasons, it's back to normal now.
The Acer Aspire One AOD270 and the same hardware rebranded as
Packard Bell Dot SC need a couple of keymap fixups:
1. The switch-video-mode key does not do anything. Standard acer-wmi
maps scancode 0x61 to KEY_IGNORE since typically these events are
duplicate with the ACPI video bus. But on these models the ACPI video
bus does not send events for this key, so map it.
2. The Brightness up / down hotkeys send atkbd scancode 0xce / 0xef
which by default are mapped to KEY_KPPLUSMINUS and KEY_MACRO.
These actually are duplicate events with the ACPI video bus,
so map these to KEY_IGNORE.
The key doesn't create a release event. This is a fix to make it work properly. I made sure the product is generic to work on all Victus laptops.
This fix#23006.
This adds support for Fn+PrtSc on my Lenovo Thinkpad Extreme gen 2. Judging by the picture on the key, it should probably instead of prog2 be "selective_screenshot" (that is a possible value from judging this list e18d950ce5/keynames.txt ) but that does not register with evtest at all. With this change, evtest reports:
```
Event: time 1661081631.027773, type 1 (EV_KEY), code 149 (KEY_PROG2), value 1
Event: time 1661081631.027773, -------------- SYN_REPORT ------------
Event: time 1661081631.027886, type 1 (EV_KEY), code 149 (KEY_PROG2), value 0
Event: time 1661081631.027886, -------------- SYN_REPORT ------------
```
I am not sure if systemd is the right place to add this, if not, please refer me somewhere else.
This fixes the discrepancies in the coordinate ranges for the touchpad, touchpad in this device(NS13A2) is generic and the same one is used in most models.
