How do you enable the new extensions in Metacity 2.16?

Hi all,

I'm wanting to try out metacity 2.16's new eye candy extensions in GNOME 2.16 but I'm not sure how to enable them. Is there a use flag available or do we have to manually compile the source code ourselves. If anyone could let me know that would be greatly appreciated. Thanks.

Craig

You only need to edit metacity ebuild and change --disable-compositor to --enable-compositor, digest and emerge it and then with gconf-editor check /apps/metacity/general/compositing_manager, but surely you obtain a blue screen wih shadows.

--enable-compositor requires libcm at configure time but it's not present in the system. Do you know what's that?

Dizzutch · Post by **Dizzutch** » Wed Sep 13, 2006 8:02 pm

libcm doesn't exist yet in portage. so unless you install it manually you're best leaving the composite disabled until it is added.

I've googled for it but didn't even find the libcm sources. Is it related with gnome, xorg?

You can get libcm from GNOME CVS.

There is also a version in the Xgl overlay: http://www.gentoo-wiki.org/Xgl#Checking ... ge_Overlay

Code: Select all

ebuild metacity-blahblah.ebuild digest

It will surely help you

Thanks, nrl and Dizzutch, for the source.
I couldn't compile libcm from CVS (errors), but the ebuilds in Hanno's Xgl overlay worked fine (Mesa-6.5.1*, libcm-0.22*). With those installed I could finally emerge metacity with --enable-composite. However if I check on compositing_manager for metacity, It crashes. Seems like GLX_texture_from_pixmap extension is missing.
Do you know if I've to enable it in the xorg conf? or may be this requires something else like Xgl? Mine is a radeon 9250 and it's supposed to be supported. Thanks for the help.

It's only available on certain cards, IIRC only ATI and Intel cards at the moment, Nvidia doesn't support it yet. This is described on the GNOME release notes for 2.16

gnome.org release notes wrote:Not yet enabled by default, new compositing affects are only available when Metacity is compiled with the special --enable-compositor option. The new compositing features also depend on support for the GLX_texture_from_pixmap extension, which is only available to owners of Intel i830 to i945, and ATI Radeon 7000 to 9250 chips at the present time.

Search the output of

glxinfo

for that flag. It needs to be mentioned in there for it to work.

My ATI card is supported. The packages required are installed and configured to enable composite.
The AIGLX option is set in the xorg.conf. Seems that the texture_from_pixmap extension is loaded.

Does anyone have a DIRECT link for libcm or a solution to this missing lib

you need to revdep-rebuild

Metacity compositing works well for me under AIGLX.

INSTALLATION TIPS:

* Make sure AIGLX and Composite are enabled in your xorg.conf as described here. (With AIGLX but w/o Composite, you get nothing; with Composite but w/o AIGLX, all your windows turn into shaded blue boxes.)

* If you are using the open source radeon driver like me, in the "Device" section make sure that you use the default XAA render method rather than EXA. Also, and this is critical, have the following line:

Code: Select all

Option     "XAANoOffscreenPixmaps" "True"

Without this the Xserver will crash. (Also mentioned in the above.)

* Here are the x11-libs/libcm-0.1.1 and x11-wm/metacity-2.16.3 ebuilds:

Stick them in your local overlay and keyword unmask libcm.

* In the GConf editor, under apps/metacity/general, activate "compositing_manager". Voila.

RESULTS:

There is a "bounce" effect when you focus or grab/release a window; since I use sloppy focus, it's a little much -- I'd rather have a wobble/shimmy effect as I move a window. When you kill a window, there's an "exploding shards" effect that is rather cheesy. Finally, there's a "shrink" effect when minimizing. I hope these will be options in version 2.18 so one can pick and choose.

Transparency and alpha blending of terminals, menus, and transient windows work quite well.

Anyway, this is all better than Beryl, which gives me a headache. (The same xorg.conf tips above apply to Beryl, obviously with different Portage installation.)

HTH.
