Tujuan dari proyek langsung Accelerated GL X (AIGLX) adalah menambahkan efek 3D untuk sehari-hari sistem desktop. Hal ini dilakukan dengan menerapkan (http://opengl.org) OpenGL dipercepat efek menggunakan Mesa (http://www.mesa3d.org) open source implementasi OpenGL. Untuk mempelajari lebih lanjut tentang proyek AIGLX, lihat situs Web ini:

Saat ini, AIGLX mendukung satu set kartu video terbatas dan menerapkan hanya beberapa efek 3D. Namun, jika Anda memiliki salah satu dari kartu-kartu, AIGLX fitur dalam versi saat ini dapat Fedora memberikan anda beberapa wawasan ke dalam permen mata yang akan datang nanti Fedora dan RHEL distribusi.
Untuk menggunakan AIGLX, Anda harus memiliki salah satu kartu video, berikut didukung :
• ATI video cards — The ATI Radeon 7000 through X850 video cards are supported. Generations r100 through r400 are included.
• Intel video cards — The Intel i810 and i830 through i945 Intel video cards are supported.
• 3DFX video cards — 3DFX Voodoo3 through Voodoo5 video cards should work, but
have not been tested yet. (3DFX was bought out by NVIDIA a few years ago.)
• Intel video cards — The Intel i810 and i830 through i945 Intel video cards are supported.
• 3DFX video cards — 3DFX Voodoo3 through Voodoo5 video cards should work, but
have not been tested yet. (3DFX was bought out by NVIDIA a few years ago.)
Karena infrastruktur rendering langsung (DRI) diperlukan untuk AIGLX, kartu yang tidak mendukung fitur yang tidak dapat digunakan. Dukungan untuk kartu NVidia sedang dalam pengembangan. Kartu yang diketahui tidak bekerja dengan AIGLX termasuk ATI Rage 128 dan Mach 64, Matrox G200 melalui G550, dan 3dfx Voodoo 1 dan 2.
Jika Anda memiliki kartu video didukung, trik berikutnya dalam mendapatkan AIGLX untuk bekerja di Fedora adalah memiliki paket perangkat lunak yang tepat diinstal. Jika Anda telah menginstal desktop GNOME, Anda harus sudah memiliki semua paket yang Anda butuhkan. Paket tersebut termasuk compiz (untuk compiz window manager), glx-utils, gtk2-engine, mesa-libGL, mesa-libGLU, dan xorg-x11- drv-ati atau xorg-x11-drv-i810 (tergantung pada driver kartu video kebutuhan Anda.
Efek Desktop fitur untuk melihat efek yang telah dilaksanakan sejauh ini. Untuk mengaktifkanEfek desktop dari desktop GNOME, pilih : System Preferences- Look and Feel Desktop Effects. Ketika Efek Desktop pop-up muncul, pilih Aktifkan Desktop Efek. Mengaktifkan hal ini sebagai berikut: Dari desktop KDE, buka Pengaturan Sistem jendela, lalu pilih : Desktop-Desktop Effects. Kemudian pilih Enable Desktop Effects.
• Stops the current window manager and starts the Compiz window manager.
• Enables the Windows Wobble When Moved effect. With this effect on, when you grab the title bar of the window to move it, the window will wobble as it moves. Menus and other items that open on the desktop also wobble.
• Enables the Workspaces on a Cube effect. Drag a window from the desktop to the rightor the left and the desktop will rotate like a cube, with each of your desktop workspacesappearing as a side of that cube. Drop the window on the workspace where you want it to go. You can also click on the Workspace Switcher applet in the bottom panel to rotate the cube to display different workspaces.Berikut ini adalah beberapa efek yang menarik Anda bisa mendapatkan dengan desktop 3D AIGLX Anda:
• Spin cube — Hold Ctrl+Alt keys and press right and left arrow keys. The desktop cube spins to each successive workspace (forward or back).
• Slowly rotate cube — Hold the Ctrl+Alt keys, press and hold the left mouse button, and move the mouse around on the screen. The cube will move slowly with the mouse among the workspaces.
• Tab through windows — Hold the Alt key and press the Tab key. You will see reduced versions of all your windows in a strip in the middle of your screen, with the current window highlighted in the middle. Still holding the Alt key, press Tab or Shift+Tab to move forward or backwards through the windows. Release the keys when the one you want is highlighted
• Scale and separate windows — If your desktop is cluttered, hold Ctrl+Alt and press the up arrow key. Windows will shrink down and separate on the desktop. Still holding Ctrl+Alt, use your arrow keys to highlight the window you want and release the keys to have that window come to the surface.
• Scale and separate workspaces — Hold Ctrl+Alt and press the down arrow key to see reduced images of the workspace shown on a strip. Still holding Ctrl+Alt, use right and left arrow keys to move among the different workspaces. Release the keys when the workspace you want is highlighted.
• Send current window to next workspace — Hold Ctrl+Shift+Alt keys together and press the left and right arrow keys. The current window will move to the next workspace to the left or right, respectively.
• Slide windows around — Press and hold the left mouse button, and then press the left, right, up, or down arrow keys to slide the current window around on the screen.
• Slowly rotate cube — Hold the Ctrl+Alt keys, press and hold the left mouse button, and move the mouse around on the screen. The cube will move slowly with the mouse among the workspaces.

Jika Anda bosan jendela bergoyang-goyang dan kubus berputar, mematikan AIGLX efek 3D dan Metacity kembali sebagai window manager yang bisa dilakukan cukup sederhana. Cukup pilih : System Preferences-Look and Feel-Desktop Efek lagi dan beralih dari Aktifkan Desktop Efek tombol untuk mematikan fitur tersebut.
Jika Anda memiliki kartu video didukung, tetapi menemukan bahwa Anda tidak dapat menghidupkan Desktop Efek, periksa bahwa X server dimulai dengan benar. Secara khusus, pastikan bahwa Anda File /etc/X11/xorg.conf dikonfigurasi dengan benar. Pastikan bahwa dri dan glx dimuat dalam Modul bagian. Juga, tambahkan bagian ekstensi yang muncul sebagai berikut:
Section "extensions" Option "Composite" EndSection
Pilihan lain adalah menambahkan baris berikut ke file /etc/X11/xorg.conf di Device bagian:
Option XAANoOffscreenPixmaps"
Opsi XAANoOffscreenPixmaps akan meningkatkan kinerja. Periksa /var/log/Xorg.log.0 file untuk memastikan bahwa DRI dan AIGLX fitur yang dijalankan dengan benar. Pesan dalam file yang dapat membantu Anda men-debug masalah lain juga.
