HOWTO: configure compiz
 
After finding a way to configure compiz using only the official package, I thought it would be nice to share. We'll assume a working compiz installation and vanilla path/env.

Quote:

mkdir ~/.compiz
compiz --replace ini decoration wobbly fade minimize cube move place resize rotate scale switcher water zoom &
kde-window-decorator &
This should turn on compiz with all the default plugins, and create a bunch of .conf in ~/.compiz/options/. Note that that's 3 lines of commands.

To set up the cube's top/bottom and skydome pictures, you can modify ~/.compiz/options/cube-screen0.conf. Dig around in there. Lot's of fun.

To set up compiz as default windows manager, we modify ~/.compiz/options/decoration-allscreens.conf with:
Quote:

command=kde-window-decorator
and create a script in ~/.kde/env/ with content:
Quote:

#! /bin/sh
KDEWM="compiz ini"
export KDEWM
Restart X (Ctrl-Alt-Backspace) and you're all done :)

Most of this guide stolen from WulfNStein, raska and erklaerbaer.

note to the wary, I can't seem to change back to kwin now ...

EDIT: Ok, remove all modifications, runlevel 3, xwmconfig to xfce, startx, logout, xwmconfig to kde, back to kwin now (kde-window-decorator does not display chinese in the titlebar)

Hi, I've tried lots of different compiz comand lines and I always get this error:

Code:

compiz: Another window manager is already running on screen: 0
compiz: No manageable screens found on display :0.0

Like, duh, I know another window manager is running, I said "--replace"

Did you have compiz working as a user or root?

I have not been able to get all effects as user. Curiosity I ran it as root on kde desktop and have wobbles, window borders etc. Pretty useless if it only works for root. Seems to me a permission issue but I haven't seen anything about permissions and compiz.

randomsel 07-10-2007 11:24 PM

That's strange, the people at the compiz forum recomends *not* to run compiz as root. If you're getting wobbly, compiz is working.

I found out that many of them need special key presses (Ctrl-Alt-left/right/up/down) to activate the effect, and the order of load for the plugins is important (ish).

justwantin 07-11-2007 04:24 AM

I never use root logged into kde except just right after an install for a couple things. But with root available I thought I'd try compiz since it wasn't working right in a user account.

Seems all works as root except for the much talked about cube for which not even a config file is created. That might just be my rather dated geforce2 mmx/mx 400.

Compiz starts up with user but no window borders, wobble, etc. Not all that important to me but once I've sorted things out and built packages there will be some other workstation's whose owners will want the eye candy.

mmmh... are you running kde-window-decorator right after running compiz?
After logging in, open a terminal (i.e. Konsole) and try these two commands, please tell us if you get the 3D desktop working afterwards:
Code:

compiz --replace decoration wobbly fade minimize cube move place resize rotate scale switcher water zoom &
kde-window-decorator &

Keep the ampersand signs (&) at the end, those mean to send your commands to the background so they don't crash if you close your terminal program.

Thanks to randomsel for the above tips. I hope to find the time to review them, so I can setup a skydome and some (mis)configurations and post back here my results ;)

randomsel 07-11-2007 10:19 AM

Apropos of skydome, gradient works, but can't make it work with an image. Please share if you comes up with a solution (or an image that works). Same for top/bottom image.

Most of these configurations are undocumented, but obvious after you test them out, like 'in=1' in the cube configuration shifts your point of view to the "inside" of the cube :rolleyes: .

I am sorry for intervening in this post, but I think I should not start a new thread since this one discusses problems with configuring compiz.
So I am running Slackware Linux 12.0 with kernel vmlinuz-generic-smp-2.6.21.5-smp. My video card is 00:02.0 VGA compatible controller: Intel Corporation 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device (rev 03)
So, following the instructions in the first post, I added

Section "Extensions"
Option "Composite" "Enable"
EndSection

to my xorg.conf. When I run:
compiz --replace ini decoration wobbly fade minimize cube move place resize rotate scale switcher water zoom &
I get the following:

libGL warning: 3D driver claims to not support visual 0x51
compiz: GLX_EXT_texture_from_pixmap is not supported by direct rendering context, trying indirect rendering context instead
compiz: GLX_EXT_texture_from_pixmap is missing
compiz: Failed to manage screen: 0
compiz: No manageable screens found on display :0.0

and the borders of the windows freeze and all I can do is kill kde and start in anew.

Any suggestions what is wrong?
First of all does my video card support the "shinies" that compiz allows?

Regards,
Martin

randomsel 07-11-2007 11:41 AM

seems you haven't enabled dri yet, check out the stickied thread about enabling 3d acceleration on x11

tramni1980 07-11-2007 12:02 PM

glxinfo | rendering:
libGL warning: 3D driver claims to not support visual 0x51
direct rendering: Yes

So I do have direct rendering ...

I wonder if my video card supports what compiz offers?

rosepower 07-11-2007 01:47 PM

Hi,

I have an ATI Radeon 9600, and i also get this message:

LibGL warning: 3D driver claims to not support visual 0x4b
compiz: GLX_EXT_texture_from_pixmap is not supported by direct rendering context, trying indirect rendering context instead
compiz: GLX_EXT_texture_from_pixmap is missing
compiz: Failed to manage screen: 0
compiz: No manageable screens found on display :0.0

Should i install the proprietary drivers ???
I have this post here: h**p://www.linuxquestions.org/questions/showthread.php?t=568200

Regards

PS:please move or delet my post if you think it does not belong in this thread

Thanks raksa,

Yes, I'm using the complete command in two lines with "&" following each line. I played around a bit more and it seems that I can get something worthwhile if I leave out the "ini", e.g.

# #!/bin/bash
# compiz --replace decoration wobbly fade minimize cube move place resize rotate scale switcher water zoom &
# kde-window-decorator &

I have a ~/.compiz directory and some config files that were created in it when I first ran with "ini" in the script. There is a ~/.kde/env directory with your short script in it named start-compiz (for lack of any other name) and it is executable.

If I run this script manually:

# #!/bin/bash
# compiz --replace ini decoration wobbly fade minimize cube move place resize rotate scale switcher water zoom &
# kde-window-decorator &

I get the following error:

" kde-window-decorator: Could not acquire decoration manager selection on screen 0 display ":0.0" "

which I now think is a failure to read the ./compiz configs and not a permission problem.


I'll have to do some more research.

WulfNStein 07-11-2007 07:58 PM

For configuring your video card to handle compiz I strongly recommend reading the tutorials on the compiz site.....

http://compiz.org/Documentation/Documentation

There are steps for configuring Nvidia, ATI, and Intel cards.

There is also a lot of helpful information on there forums.

http://forum.compiz.org/

Good luck.

I had a strange and disappointing experience with Compiz.

Fake:

First of all, I created a brand new user: "fake". I didn't want to risk my environment. I killed X, logged in as "fake" and installed Compiz. What I call "installation" is nothing more than running these commands:

Code:

rm -rf ~/.compiz
mkdir ~/.compiz
compiz --replace ini decoration wobbly fade minimize cube move place resize rotate scale switcher water zoom &
kde-window-decorator &

I didn't get any error messages, and Compiz worked flawlessly. All features worked. Impressive! I killed X and logged in as "fake" again. Compiz was still there working flawlessly. I restarted X once again, Compiz was hanging tough. So I assumed it was installed for good. But the first funny thing in this story is that I inspected ~/.compiz and it was empty! No files, zilch, nada.

Myself:

So I killed X and logged in as myself. Installed Compiz and this time I got error messages. Something more or less like "file such and such not found, using defaults". Or something like that. The message was echoed about 6 or 8 times, and about 6 or 8 files were created inside ~/.compiz. Well, this time Compiz did not work at all. It was running in the background, but none of the effects worked. Sometimes it would even make KDE freeze completely and force me to kill X.

Myself with empty home:

So I dropped to runlevel 3 and moved everything in my home directory elsewhere and ran startx. I was still myself, but with an empty home directory. New installation and, again, I got the same error message about 6 or 8 times in the console, and about 6 or 8 files were created inside ~/.compiz. Now Compiz sort of worked, just a couple of features. I restarted X several times and nothing improved. And Compiz never started itself automatically as when I experimented with the "fake" user. Now I always had to run it manually.

My old self again:

So I deleted everything from my home directory, restored the backup and installed Compiz as myself with all the old baggage once more. Again, it ran in background, but none of the effects worked.

Faketoo:

I made another new user: "faketoo". Then I killed X, logged in as "faketoo" and installed Compiz. It would work fine with another brand new user like "fake", right? Wrong. I got the same error message and just a couple of features worked.

Fake:

Finally, I logged in as Mr. fake again and Compiz ran just fine. Automatically. I didn't have to "install" it. It was there already. I figured I could just copy whatever Mr. fake had in his ~/.compiz directory, but it's still empty.

Then I gave up. Too bad. It was fun while it lasted.
