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

.TH TOUCHPAD-EDGE-DETECTOR "1"
|
|
.SH NAME
|
|
touchpad-edge-detector \- print the axis ranges for a touchpad device
|
|
.SH SYNOPSIS
|
|
.B touchpad-edge-detector [--help] \fIWxH /dev/input/eventX\fR
|
|
.SH DESCRIPTION
|
|
.PP
|
|
The
|
|
.B touchpad-edge-detector
|
|
tool reads touchpad events from the kernel and records the minimum and
|
|
maximum coordinates based on user input. This is an interactive tool, the
|
|
user must move a finger around the touchpad, attempting to trigger an
|
|
event at all edges of the touchpad.
|
|
.PP
|
|
To terminate the event collection and print a summary, press Ctrl+C. It is
|
|
recommended that the tool is run several times to guarantee a reliable
|
|
result.
|
|
.SH OPTIONS
|
|
.TP 8
|
|
.I WxH
|
|
The width and height of the touchpad in mm. For a touchpad 100mm wide and
|
|
75mm high, the argument is thus \fI100x75\fR. This is a required argument.
|
|
.TP 8
|
|
.I /dev/input/eventX
|
|
The event node of the touchpad to read events from. A list of possible event
|
|
nodes can be obtained with either one of the following commands: \fBlibinput
|
|
record\fR, \fBevemu-record\fR, or \fBevtest\fR. Alternatively the event node
|
|
for a device is listed in the \fBHandlers=\fR line \fI/proc/bus/input/devices\fR.
|
|
This is a required argument.

|
|
.SH NOTES
|
|
.PP
|
|
On completion, this tool prints a summary of the collected events and a
|
|
suggested udev rule. Due to rounding errors it is rare to get an exact match
|
|
for the touchpad's dimensions, but any discrepancy of more than 5mm should
|
|
be corrected with the suggested udev rule.
|
|
.PP
|
|
The udev rule should be simplified and submitted as a pull request to the
|
|
system repository at \fIhttps://github.com/systemd/systemd\fR. For further
|
|
guidance, see the file \fI/usr/lib/udev/hwdb.d/60-evdev.hwdb\fR.
