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

Clickpads with a fake right button
|
|
==============================================================================
|
|
|
|
libinput relies on the kernel to label :ref:`Clickpads <touchpads_buttons_clickpads>`
|
|
with the ``INPUT_PROP_BUTTONPAD`` property so it can enable the correct
|
|
:ref:`clickpad_softbuttons`. Clickpads are not expected to have a right button
|
|
since the whole surface can be depressed.
|
|
|
|
A common bug encountered with :ref:`Clickpads <touchpads_buttons_clickpads>`
|
|
is that the device advertises a physical right button where no such button
|
|
exists. This is usually a bug in the firmware of the device and causes the
|
|
following warning to be emitted by libinput::
|
|
|
|
"<device name> clickpad advertising right button"
|
|
|
|
The user-visible effect of this is usually negligible since these devices
|
|
cannot actually trigger a right click and libinput's default behaviors for
|
|
clickpads work as expected.
|
|
|
|
However, we should nonetheless correct the device to get rid of this warning
|
|
and avoid potential issues with future features. The :ref:`device-quirks`
|
|
provide a simple way to disable the fake right button on the device. The
|
|
following quirk disables the right button on the MyModel laptop from the
|
|
MyVendor OEM::
|
|
|
|
[MyVendor MyModel Touchpad]
|
|
MatchName=Foo Bar Touchpad
|
|
MatchUdevtype=touchpad
|
|
MatchDMIModAlias=dmi:*svnMyVendor:pnMyModel:*
|
|
AttrEventCode=-BTN_RIGHT
|
|
|
|
The name of the device can be obtained using :ref:`libinput record <libinput-record>`,
|
|
the modalias match is a shell-style glob against the value of ``/sys/class/dmi/id/modalias``.
|
|
In most cases, matching should be against ``svn`` (system vendor) and one of
|
|
``pn`` (product name) or ``pvr`` (product version), whichever provides a
|
|
useful description of the individual laptop model. See the
|
|
:ref:`device-quirks` documentation for details on testing local quirks.
|
|
|
