Matikan kunci SUPER selama aplikasi layar penuh

Apakah ada cara untuk mematikan kunci SUPER selama sesi bermain game atau aplikasi layar penuh secara umum?

pengantar

Skrip berikut menonaktifkan Superkunci jika ada jendela X11 dalam mode layar penuh. Ini dimaksudkan untuk ditambahkan sebagai aplikasi startup, tetapi juga dapat berjalan dalam mode yang berdiri sendiri.

Pemakaian

Untuk menjalankan skrip secara manual, cukup dilakukan:

python disable_super_key.py

Untuk membuat skrip memulai secara otomatis saat login, lihat Bagaimana saya memulai aplikasi secara otomatis saat login?

Memperoleh kode sumber skrip

Seseorang dapat menyalin sumber skrip dari jawaban ini, atau mendapatkannya melalui kloning repositori GitHub saya .

Instruksi untuk mereka yang memiliki git:

1. cd /opt
2. sudo git clone https://github.com/SergKolo/sergrep.git
3. chmod -R +x sergrep

Script akan berlokasi di /opt/sergrep/disable_super_key.py

Debugging

Dalam hal diperlukan debugging, ganti baris 32 dari debug = Falsemenjadi debug = Truedan jalankan skrip dari baris perintah
