Gara-gara komentar di status Facebooknya om Walesa jadi kepengin menjajal KDE 4.9 Beta2. Setelah semalaman ketiduran menunggu upgrade KDE, baru pagi ini saya punya kesempatan menjajalnya.

Ritual upgrade dengan pacman -Syu berjalan lantjar djaja. Namun, ketika saya masuk ke desktop ada hal yang tidak biasa. Hal yang saya temui adalah kwin tidak berjalan sebagaimana mestinya. Iseng-iseng saya jalankan ulang kwin dengan perintah kwin --replace ternyata ada masalah dengan kwin decoration. Kwin decoration yang saya pakai ternyata bukan Oxygen tetapi Oxygen Transparent dan itu biang keladinya. 😂

Setelah menghapus berkas kwinrc di $HOME/.kde4/share/config, baru saya bisa masuk ke desktop KDE 4.9 Beta2 dengan sukses! 😀

Satu hal yang membuat saya cukup terkesan dengan KDE 4.9 Beta2 ini adalah loading yang super cepat dibanding dengan KDE seri 4.8.x. 👍🏽
