Cara Fix Tombol PrintScren Tidak Berfungsi di UbuntuDDE

Sampai saat ini saya saya masih nyaman dengan Desktop Environment (DE) Deepin di Ubuntu atau yang dinamakan UbuntuDDE. Hingga pagi ini mencoba shortcut Print Screen dengan memencet tombol di keyboard tidak muncul apa-apa. Sedangkan pada DE Ubuntu on Wayland, akan segera muncul tanda bahwa gambar telah disimpan; ke folder Pictures pada Home.

Software screenshot di Ubuntu 20.04 LTS saya adalah software default dengan nama Screenshot. Belakangan saya ketahui bahwa namanya adalah gnome-screenshot. Ketika saya ketikkan perintah di terminal screenshot --version, tidak muncul. Baru ketika diketikkan gnome-screenshot --version, muncul gnome-screenshot 3.36.0.

Ketika diklik Screnshot pada daftar aplikasi, akan muncul:

Sekarang saya coba menghapus aplikasi screenshotnya dan mengganti dengan deepin screenshot.

Pada terminal saya ketikkan: sudo apt remove gnome-screenshot

Selesai. Deepin-screenshot sudah terinstall dan sudah muncul di daftar aplikasi.

Note: Saya coba jalankan Deepin-screnshot, muncul hitam saja. Tampaknya Deepin-Screenshot tidak bisa bekerja pada Ubuntu on Wayland.

Saya coba logout dan login pada Desktop Environment Deepin (UbuntuDDE). Saya bisa menjankan deepin-screenshot. Sayang saya tidak bisa mengambil gambar dengan tombol print-screent.

Saya coba buka terminal dan mengetikkan perintah:

sudo chmod -R 777 Pictures

Alhamdulillah. Sekarang saya bisa mengambil screenshot dengan memencet tombol PrintScreen atau PrtSc pada keyboard laptop.

Hasil tangkapan layar tersimpan pada Desktop. Sekarang bagaimana caranya agar hasil tangkapan layar aplikasi Deepin-screenshot tersimpan di folder pictures? Saya coba melakukan screenshot lalu menyimpannya di folder Pictures, dengan memilih save to specified folder. Setelah itu saya coba mengambil screenshot lagi, lalu pilih autosave. Sekarang setiap kali saya menekan tombol PrtSc / Print Screen, gambar disimpan di folder Pictures.
