Konfigurasi Nixos (Pantheon + BSPWM) Thinkpad X220

JagoTekno.com - Sebenarnya sudah lama sekali saya ingin menggunakan Pantheon Desktop milik ElementaryOS. Alasannya karena simple dan minimalis juga rasanya lebih dekat ke MacOs terutama pada file managernya.

Untungnya Nixos sudah menyertakan Pantheon Desktop pada pilihan saat instalasi Nixos.

Lalu saya juga masih ingin menggunakan WM only pada system, jadi saya juga ingin menjalankan BSPWM sebagai window manager. (dan sekarang lebih betah pakai window manager)

Begini setup yang saya lakukan.

1. Install Nixos + Pantheon Desktop
2. Melakukan konfigurasi pada file configuration.nix untuk mengaktifkan BSPWM secara otomatis.

Karena desktop ini menggunakan BSPWM maka saya juga menambahkan Polybar untuk menampilkan barnya.

Tercatat saat menulis artikel ini saya sudah melakukan 40 kali rebuild system nixos.

Konfigurasi terakhir saya sudah simpan sehingga menjadi seperti ini :

# Edit this configuration file to define what should be installed on
# your system.  Help is available in the configuration.nix(5) man page
# and in the NixOS manual (accessible by running ‘nixos-help’).

Untuk menggunakan konfigurasi ini, seperti biasa anda hanya perlu mengedit file /etc/nixos/configuration.nix

Kemudian melakukan rebuild sudo nixos-rebuild switch

Tunggu sampai selesai, kemudian restart komputer anda.

Konfigurasi di atas dibuat khusus untuk dijalankan pada laptop Thinkpad X220.

Akhir kata

Konfigurasi ini masih jauh dari sempurna. Masih terdapat beberapa fitur yang tidak saya harapkan ada pada system saat ini.

Meski demikian menggunakan Nixos system memang terasa sangat imutable.
