最近、私はThinkpad 10第2世代タブレットでLinuxをプレイしています。現在、Fedora 24が実行されています。 USBスティック（ライブモード）から起動すると、タッチスクリーンが機能し、Wacom 5020 HIDとして検出されますが、インストール後にタッチスクリーンが機能せず、xinputが検出されません。
以下は、ライブイメージとインストールされているOS（それぞれ@liveと@install）から取得した情報の一部です。
メモ:lspciとlsusbは同じなので、30,000文字の制限を避けるために省略しました。

ご覧のとおり、インストールされているオペレーティングシステムにwacom関連のエラーがいくつかありますが、その理由と解決策がわかりません。 Ubuntuページのタッチスクリーン関連Wikiをフォローしてみましたが、サイコロはありません。 ttySが32個ありますが、ttyS0、ttyS4、ttyS5のみ終了せず、screen3つすべて画面をタッチしても何も入力されません。
ここで誰もこの問題や同様の問題を経験したことがありますか？それでは、どうやって解決しましたか？
上記の情報は、ライブモードのシングルブートまたはインストールされているオペレーティングシステムのシングルブートからの情報ではありません。あるモードから別のモードに再起動し、必要に応じて情報を収集しました。
編集＃1：ログビューアで時間を費やした後、入力デバイスudevとsystemd-logind入力デバイスの登録に関するログメッセージが偶然に見つかりました。ご覧のとおり、ライブモードではすべてがうまく機能しますが、インストールされているOSでは次のエラーが記録されます。
systemd-logind: failed to take device /dev/input/event7: Invalid argument
xf86OpenSerial: Cannot open device /dev/input/event7
Wacom HID 5020 Pen: Error opening /dev/input/event7 (Permission denied)
ログメッセージは降順に並べ替えられます（GNOMEログビューアはメッセージを表示しているとおりに保存します）。
