1.1     ! imil        1: ## Eye Candy for NetBSD 5.0
        !             2: 
        !             3: Since a couple of years, there are some Window Managers providing shiny 3D effects like a cube-mapped-desktop, wobbly windows and various other animations.
        !             4: 
        !             5: NetBSD is capable of dealing with those interfaces, but their installation is not yet straightforward. Here are the couple of steps you'll have to go through in order to impress your friends with a modern 3D NetBSD desktop.
        !             6: 
        !             7: ### Enable DRM in the kernel
        !             8: 
        !             9: Depending on the graphic card you are using, add one of the following to your kernel configuration:
        !            10: 
        !            11:        i915drm*        at vga?         # Intel i915, i945 DRM driver
        !            12:        mach64drm*      at vga?         # mach64 (3D Rage Pro, Rage) DRM driver
        !            13:        mgadrm*         at vga?         # Matrox G[24]00, G[45]50 DRM driver
        !            14:        r128drm*        at vga?         # ATI Rage 128 DRM driver
        !            15:        radeondrm*      at vga?         # ATI Radeon DRM driver
        !            16:        savagedrm*      at vga?         # S3 Savage DRM driver
        !            17:        sisdrm*         at vga?         # SiS DRM driver
        !            18:        tdfxdrm*        at vga?         # 3dfx (voodoo) DRM driver
        !            19: 
        !            20: For example, if your graphic card has an intel 945GM chip and your architecture is amd64-based:
        !            21: 
        !            22:        # cd /usr/src/sys/arch/amd64/conf
        !            23:        # cp GENERIC MYKERNEL
        !            24:        # echo "i915drm*        at vga?" >> MYKERNEL
        !            25: 
        !            26: Then recompile and copy your kernel [as usual](http://www.netbsd.org/docs/guide/en/chap-kernel.html as usual).
        !            27: 
        !            28: ### Modular Xorg
        !            29: 
        !            30: The next step involves the Xorg server. Xorg 1.4.2 which is the version bundled with NetBSD 5.0 has no real [AiGLX](http://en.wikipedia.org/wiki/AIGLX) support. While Xorg.0.log will pretend AiGLX is enabled, it does not load the X dri driver related to your GPU. In order to have full AiGLX support, you will have to use pkgsrc's modular Xorg.
        !            31: Refer to [this article](http://wiki.netbsd.se/How_to_install_modular_Xorg) see how to achieve this simple -but long- task.
        !            32: 
        !            33: Once modular Xorg is installed, you'll have to tell *gdm* not to start the base Xorg server, but the new one installed by *pkgsrc*. Edit */usr/pkg/etc/gdm/custom.conf* and add the following lines:
        !            34: 
        !            35:        [server-Standard]
        !            36:        name=Standard server
        !            37:        command=/usr/pkg/bin/X vt05 -audit 0
        !            38:        flexible=true
        !            39: 
        !            40: Those using *startx* instead should create a *${HOME}/.xserverrc* with the following content:
        !            41: 
        !            42:        exec /usr/pkg/bin/X vt05 -audit 0
        !            43: 
        !            44: Update your *${PATH}* variable so */usr/pkg/bin* comes before */usr/X11R{6,7}/bin*, i.e.:
        !            45: 
        !            46:        PATH=${HOME}/bin:/bin:/sbin:/usr/bin:/usr/sbin:/usr/pkg/bin
        !            47:        PATH=${PATH}:/usr/pkg/sbin:/usr/games:/usr/local/bin:/usr/local/sbin
        !            48:        PATH=${PATH}:/usr/X11R7/bin:/usr/X11R6/bin
        !            49:        export PATH
        !            50: 
        !            51: ### Xorg configuration
        !            52: 
        !            53: Exit from any X Window environment you might be using and run:
        !            54: 
        !            55:        # Xorg -configure
        !            56: 
        !            57: This should produce a valid *xorg.conf* file in your *${HOME}* directory, just copy it to */etc/X11/xorg.conf*. Here is a typical *xorg.conf* file with necessary bits for DRI, AiGLX and Composite extensions to be loaded and operationals:

        !           204: In order to test your new X Window powers, install the following packages using your favourite method (pkgsrc, pkg_add, pkgin...):

        !           212: 
        !           213: As of 26/11/2009, *pkgsrc-2009Q3* binary version of those packages is 0.6.0. If you'd like to use the latest compiz version (0.8.4), you'll have to install it using current version of *pkgsrc*.
        !           214: 
        !           215: Once done, if you use the GNOME desktop, start compiz with this little script:

        !           226: 
        !           227: 0.6 version of compiz is old and suffers a known bug, instead of using metacity's themes, it draws white translucent borders. A [patch](http://cgit.compiz.org/compiz/core/patch/?id=27cc9c5178921ce6d6266f4b00303913163be7ee) is available for the gtk-window-decorator program that fixes it, but if you don't feel like patching / compiling, revert to compiz's default windows decorator:
