Ubuntu 17.04でPalm検出を修正する方法

Ubuntu 16.04以降、この問題が発生しました。 Palmの検出は機能しません。 this の記事に記載されているコマンドを実行してみましたが、効果はありませんでした。

xinputの出力：

Synapticsのユーザー空間ドライバーは、Palmの検出にはあまり適していません。

Ubuntu 17.04では、libinputがデフォルトのユーザースペースドライバーです。なんらかの理由で停止されません。

ターミナルで実行する

Sudo apt install xserver-xorg-input-libinput

それをインストールします。次に再起動します。

タップはデフォルトで無効になっている場合があります。 /usr/share/X11/xorg.conf.d/40-libinput.confを編集して次のようにします。

# Match on all types of devices but tablet devices and joysticks
Section "InputClass"
    Identifier "libinput pointer catchall"
    MatchIsPointer "on"
    MatchDevicePath "/dev/input/event*"
    Driver "libinput"
EndSection


Section "InputClass"
    Identifier "libinput keyboard catchall"
    MatchIsKeyboard "on"
    MatchDevicePath "/dev/input/event*"
    Driver "libinput"
EndSection

Section "InputClass"
    Identifier "libinput touchpad catchall"
    MatchIsTouchpad "on"
    MatchDevicePath "/dev/input/event*"
    Driver "libinput"
    Option "Tapping" "True"
    Option "NaturalScrolling" "True"
EndSection

Section "InputClass"
    Identifier "libinput touchscreen catchall"
    MatchIsTouchscreen "on"
    MatchDevicePath "/dev/input/event*"
    Driver "libinput"
EndSection

Section "InputClass"
    Identifier "libinput tablet catchall"
    MatchIsTablet "on"
    MatchDevicePath "/dev/input/event*"
    Driver "libinput"
EndSection

タップおよび自然なスクロールを有効にします。
