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 LIBEVDEV-TWEAK-DEVICE "1"
|
|
.SH NAME
|
|
libevdev-tweak-device \- modify an evdev kernel device
|
|
.SH SYNOPSIS
|
|
.B libevdev-tweak-device
|
|
--abs ABS_X [--min a] [--max b] [--res c] [--fuzz d] [--flat e]
|
|
/dev/input/eventX
|
|
.B libevdev-tweak-device
|
|
--resolution res[,yres] /dev/input/eventX
|
|
.PP
|
|
.B libevdev-tweak-device
|
|
--led LED_NUML --on|--off /dev/input/eventX
|
|
.SH DESCRIPTION
|
|
.PP
|
|
The
|
|
.I libevdev-tweak-device
|
|
tool changes the properties of the evdev kernel device at
|
|
.I /dev/input/eventX.
|
|
Currently this may be used to force an LED on or off, or to change the
|
|
properties of an absolute axis (e.g. its minimum/maximum range or
|
|
resolution). Changes are permanent until the device is removed.
|
|
.SH OPTIONS
|
|
.SS Changing absolute axes
|
|
.TP 8
|
|
.B --abs axis
|
|
Change the given named ABS_ kernel axis, e.g. ABS_X. For a full list, see linux/input.h.
|
|
Each of the options
|
|
.B min, max, res, fuzz, flat
|
|
may be given.
|
|
.TP 8
|
|
.B --min v
|
|
Set the absinfo minimum to the value v
|
|
.TP 8
|
|
.B --max v
|
|
Set the absinfo maximum to the value v
|
|
.TP 8
|
|
.B --res v
|
|
Set the absinfo resolution to the value v
|
|
.TP 8
|
|
.B --fuzz v
|
|
Set the absinfo fuzz to the value v
|
|
.TP 8
|
|
.B --flat v
|
|
Set the absinfo flat to the value v
|
|
.PP
|
|
.SS Changing the x/y resolution
|
|
.TP 8
|
|
.B --resolution res[,yres]
|
|
Changes the resolution of the ABS_X, ABS_MT_POSITION_X, ABS_Y, and
|
|
ABS_MT_POSITION_Y axis to the given resolution. If only one resolution value
|
|
is provided, both x and y axis are set to the same resolution, otherwise the
|
|
first resolution value is applied to the x axes and the second value to the
|
|
y axes.
|
|
.SS Toggling LEDs
|
|
.TP 8
|
|
.B --led led
|
|
Change the given LED, e.g. LED_NUML. For a full list, see linux/input.h.
|
|
.TP 8
|
|
.B --on
|
|
Change the LED state to on
|
|
.TP 8
|
|
.B --off
|
|
Change the LED state to off
|
|
.SH NOTES
|
|
.PP
|
|
The kernel does not notify processes about absinfo property changes. Any
|
|
process that has previously obtained the absinfo from the device will remain
|
|
on the old information. This makes using this tool potentially racy, use
|
|
with caution.
