Build system (5 gaps hardened): - COOKBOOK_OFFLINE defaults to true (fork-mode) - normalize_patch handles diff -ruN format - New 'repo validate-patches' command (25/25 relibc patches) - 14 patched Qt/Wayland/display recipes added to protected list - relibc archive regenerated with current patch chain Boot fixes (fixable): - Full ISO EFI partition: 16 MiB → 1 MiB (matches mini, BIOS hardcoded 2 MiB offset) - D-Bus system bus: absolute /usr/bin/dbus-daemon path (was skipped) - redbear-sessiond: absolute /usr/bin/redbear-sessiond path (was skipped) - daemon framework: silenced spurious INIT_NOTIFY warnings for oneshot_async services (P0-daemon-silence-init-notify.patch) - udev-shim: demoted INIT_NOTIFY warning to INFO (expected for oneshot_async) - relibc: comprehensive named semaphores (sem_open/close/unlink) replacing upstream todo!() stubs - greeterd: Wayland socket timeout 15s → 30s (compositor DRM wait) - greeter-ui: built and linked (header guard unification, sem_compat stubs removed) - mc: un-ignored in both configs, fixed glib/libiconv/pcre2 transitive deps - greeter config: removed stale keymapd dependency from display/greeter services - prefix toolchain: relibc headers synced, _RELIBC_STDLIB_H guard unified Unfixable (diagnosed, upstream): - i2c-hidd: abort on no-I2C-hardware (QEMU) — process::exit → relibc abort - kded6/greeter-ui: page fault 0x8 — Qt library null deref - Thread panics fd != -1 — Rust std library on Redox - DHCP timeout / eth0 MAC — QEMU user-mode networking - hwrngd/thermald — no hardware RNG/thermal in VM - live preload allocation — BIOS memory fragmentation, continues on demand

.SH NAME
|
|
libinput\-measure\-touchpad\-tap \- measure tap-to-click properties of devices
|
|
.SH SYNOPSIS
|
|
.B libinput measure touchpad\-tap [\-\-help] [\-\-format=\fI<format>\fB] \fI[/dev/input/event0]\fR
|
|
.SH DESCRIPTION
|
|
.PP
|
|
The
|
|
.B "libinput measure touchpad\-tap"
|
|
tool measures properties of the tap\-to\-click behavior of the user. This is
|
|
an interactive tool. When executed, the tool will prompt the user to
|
|
interact with the touchpad. On termination, the tool prints a summary of the
|
|
tap interactions seen. This data should be attached to any tap\-related bug
|
|
report.
|
|
.PP
|
|
For a full description on how libinput's tap-to-click behavior works, see
|
|
the online documentation here:
|
|
.I https://wayland.freedesktop.org/libinput/doc/latest/tapping.html
|
|
.PP
|
|
This is a debugging tool only, its output may change at any time. Do not
|
|
rely on the output.
|
|
.PP
|
|
This tool usually needs to be run as root to have access to the
|
|
/dev/input/eventX nodes.
|
|
.SH OPTIONS
|
|
If a device node is given, this tool opens that device node. Otherwise, this
|
|
tool searches for the first node that looks like a touchpad and uses that
|
|
node.

.B \-\-format=summary|dat
|
|
Specify the data format to be printed. The default (or if
|
|
.B \-\-format
|
|
is omitted) is "summary". See section
|
|
.B DATA FORMATS

|
|
|
.SH DATA FORMATS
|
|
This section describes the data formats printed with the
|
|
.B \-\-format
|
|
commandline argument. Note that any of the output may change at any time.

summary
|
|
.RS 4
|
|
The
|
|
.I summary
|
|
format prints a summary of the data collected. This format is useful to
|
|
get a quick overview of a user's tapping behavior and why some taps may or
|
|
may not be detected.

dat
|
|
.RS 4
|
|
The
|
|
.I dat
|
|
format prints the touch sequence data (raw and processed) in column-style
|
|
format, suitable for processing by other tools such as
|
|
.B gnuplot(1).
|
|
The data is aligned in one row per touch with each column containing a
|
|
separate data entry.
|
|
.B libinput\-measure\-touchpad\-tap
|
|
prints comments at the top of the file to describe each column.
|
|
.PP
|
|
.B WARNING:
|
|
The data contained in the output is grouped by different sort orders. For
|
|
example, the first few columns may list tap information in the 'natural'
|
|
sort order (i.e. as they occurred), the data in the next few columns may list
|
|
tap information sorted by the delta time between touch down and touch up.
|
|
Comparing columns across these group boundaries will compare data of two
|
|
different touch points and result in invalid analysis.
|
|
.SH BUGS
|
|
This tool does not take finger pressure into account. The tap it detects may
|
|
be different to those detected by libinput if libinput's pressure thresholds
|
|
differ significantly to the kernel's pressure thresholds.
