This is just a quick how to for getting compiz working with a nvidia card and kde on slackware current.It is not meant to be an exhaustive how to and it maybe totally wrong but works for me.

Install the nvidia driver if you have not yet done so.
Edit your xorg.conf and add the following lines.

In section device.

Section "Device"
Identifier "Nvidia"
Driver "nvidia"
>--add these lines--<

Code:

	Option         "RenderAccel" "true"
	Option         "AllowGLXWithComposite" "true"

>-----stop----------<
EndSection

In section screen.

Section "Screen"
>--add these lines--<

Code:

	Option         "AddARGBGLXVisuals" "true"
	Option         "DisableGLXRootClipping" "true"

>-----stop----------<

Create a new Extentions section.

>--add these lines--<

Code:

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

>-----stop----------<

restart X
Open a termnal and run the following commands.
The list after compiz --replace is a list of plugins to load edit it to your liking there are more.

NOTE: If you can't run the kde-window-decorator --replace command.
Make sure you are using compiz-0.3.6-i486-2.tgz or higher the first build of it did not have kde-window-decorator.

You may see and error like this but don't worry about it.
compiz: Failed to load slide: freedesktop <-- this error is not critical

EDIT: Thanks erklaerbaer

If it works then you can have it auto load when kde starts by creating a script and adding it to ~/.kde

Name it startcompiz.sh

Make sure you make it executable chmod +x startcompiz.sh
And now make a second script in ~/.kde/env named compizwm.sh
mkdir ~/.kde/env if you do not have a ~/.kde/env directory

Hope this helps.

you know what? i _just_ screwed up my slackware 11 install (prior to reading this--not your fault!)

ive become very disappointed at the visual performance (crashes) and appearance (choppy) of kde. i found out just yesterday that compiz is included in slackware-current. so i installed slapt-get (and using -current repo.), ran 'slapt-get --update' and 'slapt-get --upgrade' and it screwed up the install, due to dependencies for gcc.

i did a fresh reinstall and after 'slapt-get --update' i just installed compiz via 'slapt-get --install compiz', couldnt get it to work.
ive read it needs the newer Xorg 7.1+, so i tried to install all xorg packages from 'slapt-get --search xorg' then X broke!

as you have it working, did you upgrade _everything_ to -current? i assume this would work with slackware 11, as long as compiz is installed, nvidia driver is installed, and the appropriate Xorg version is installed. do you have the X-server stuff from -current as well?

well, i guess he's using compiz included in -current and that would depend on new Xorg which is on -current also

yes i was afraid of that. when i tried to update it it ruined my system.

XGizzmo, is there anything special you did to successfully update your Xorg?

This is a full install of slackware current from a slackware-current dvd. Upgrading to -current right now is a tricky deal you must read and follow http://slackware.osuosl.org/slackwar..._AND_HINTS.TXT.

You cant mix and match slackware -11.0 and -current packages due to new gcc, glibc, and a ton of others and X11 and kde changing paths, current is all or nothing right now.

yup, i also had some problems when i upgraded to -current, but now it's fixed
here's my post on my blog : http://willysr.blogspot.com/2007/03/...e-current.html

XGizzmo: What packages needed to run compiz? is it enough to install all packages in x directory? (besides NVIdia driver)

XGizzmo: What packages needed to enable compiz? is it enough to install all packages in x directory? (besides NVIdia driver)

yes im not very familiar with following instructions that long! but i will try and follow it so i can enjoy compiz.
thanks for your time and ill try and update before the weekend.

All of x series and freetype,fontconfig, with the xf86-video* and xf86-input* drivers you don't need removed is a safe bet.

Does anyone know how to configure compiz? Looks like it has no any other way except gconf2 (which installation on slack is somehow tricky and useless except for this kind of things). I read that there is a new plugin called "ini" which allows compiz configuration through a flat-file, but can't seem to find it. Anyone?

Hey XGizzmo thanks for the great walk through, one question though. Compiz is working although I loose all my window borders, I'm suspecting it has something to do with the kde-window-decorator portion of the command. I did a clean install and a full one. What package did you install for this prob?

Thanks,
C-rin

Make sure you are using compiz-0.3.6-i486-2.tgz the first build of it did not have kde-window-decorator.

better: make a small script,that starts compiz and kde-window-decorator and make a file "set-compiz-as-windowmanager.sh" in $HOME/.kde/env/ with this content:
have a look at the startkde script, if you want to know why

Thanks ran slackpkg update and updated my compiz pack and all is good.

Thanks again!!!!

Hi, i think that i'm on the good post because you'll all seems to be very good with Nvidia !

So this is my trouble :

I've a laptop with nvidia 6800 i install the last nvidia out of X the 9755 ... the installation works well
after i start X ... the Nvidia screeshot appear and the kde appear on 1440x900 (the good screen definition)
after i want to restart ... and at this time ... my screen burn in white & black ... the computer restart well
like nothing appen and i start again X ... all thing right but just to see if i had a bad dream i restart again and, again, my
screen seems to burn in black & white at the moment of X fall down just before the computer restart !

I'm a bit affraid.
