Trying to get compiz working in Slack 12: "Another window manager"
 

I am trying to get compiz working on Slackware 12 in KDE. When I compiz --replace I get this error:
It gives me that error whether I am running kwin or not.

Can anyone help? I have already added the options to my xorg.conf.

Same problem. Have googled much and all queries about it were not answered -- just silence. Seems like everybody is asking about a very common thing, but there is no answer could be found.

Hi
Try

Yes we re speaking about this command. Exact this comand causes and error:
And is should be run separate:

If using XFCE, right click on desktop / settings / window manager tweaks and disable Compositing.

If there is no compositing menu or not running xfce check xorg.conf for the line

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

Add it to the end if it's not present. I'm running fusion without any problems but didn't use the older Compiz that comes with Slack so i can't really help more then this.

I am using KDE, not XFCE. Is there an option for that?

Like I said, I added the lines to xorg.conf.

Yeah, there is probably a compositing option in KDE that is enabled and it can't be overridden by compiz i guess. That's the case with XFCE's compositing option anyway. I never used KDE so i can't tell you where it is but search the forums or search for it and you'll find it sooner or later...

Found some pictures some time ago with KDE with transparency enabled and stuff like that so there must be a composite option somewhere in there.

AriciU, there is a KDE compositing program called kompmgr. I tried compiz both with it disabled and enabled and neither work, I still get the same message.

Same with me.

Try doing "compiz --replace ccp". That's the command used for the newer compiz fusion... maybe it'll work.

Once you've got your xorg.conf set up properly (make sure Composite and AIGLX are enabled and say so in /var/log/Xorg.0.log) you can use these scripts to start compiz:

They're very simple bash scripts, you can run the commands manually as well. They have a "LIBGL_ALWAYS_INDIRECT=TRUE" in them which afaik is only necessary for some Intel cards like the i915.

In order to use the KDE script and have Compiz work with KDE you need to get rworkman's packages:

kde-window-decorator is NOT part of the stock slackware packages. gtk-window-decorator is.

It should work without any patches. I refer you to this thread:

While compiz is nice to look at, I found that it quickly became annoying.

OK, I enabled AIGLX. I have added these lines to xorg.conf:

I still get the same error. Should I conclude that using compiz with KDE is not possible?

Well if it's not possible, I must have been dreaming... ;)

Haha, you must have posted that right after I left.

I tried the stuff in that thread, but still no luck. I noticed someone in there had the same problem as me, but I didn't see any answers.
