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:

162: ### Checklist
163:
164: Now reboot your NetBSD computer with the previously compiled kernel. When Xorg starts, you should see the following kernel messages using dmesg:
165:
166: error: [drm:pid389:i915_getparam] *ERROR* i915_getparam called with no initialization
167: i915drm0: interrupting at ioapic0 pin 16
168: error: [drm:pid389:i915_getparam] *ERROR* Unknown parameter 5
169:
170: Error messages can safely be ignored, they mean you're not running a GNU/Linux kernel >= 2.6.28.
171: Xorg.0.log now should contain the following messages:
172:
173: [...]
174: (**) AIGLX enabled
175: (II) Loading extension GLX
176: (II) LoadModule: "intel"

199:
200: Meaning your X11 environment can now play well with 3D gadgets.

202: ### Running compiz
203:
204: In order to test your new X Window powers, install the following packages using your favourite method (pkgsrc, pkg_add, pkgin...):
205:
206: wm/compiz
207: devel/libcompizconfig
208: wm/compiz-fusion-plugins-extra
209: wm/compiz-fusion-plugins-main
210: devel/compizconfig-backend-gconf
211: wm/ccsm
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:
216:
217: #/bin/sh
218:
219: # compiz 0.6's --replace does not kill properly metacity
220: pkill metacity
221:
222: # for intel cards, add INTEL_BATCH=1 to the following command
223: LIBGL_ALWAYS_INDIRECT=1 /usr/pkg/bin/compiz --replace --indirect-rendering ccp &
224:
225: If your windows don't have decorations, launch the ccsm utility and under the "Effect" section, check "Window Decoration".
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:
228:
229: $ gconftool-2 --set /apps/gwd/use_metacity_theme false --type bool
230:
231: It's now up to you to play along with ccsm and try all those shiny effects you'll soon be unable to miss :)
