marco won't die (and causes high CPU load) after compiz --replace

[benpicco]

• start a normal mate session
• compiz --replace
• CPU usage goes up (about 67% on each core here), but htop can't assign it to any process

ps aux still shows a marco process

USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
benpicco 2108 0.0 0.5 169044 7164 ? Sl 23:44 0:00 marco

• killall -KILL marco -> everything back to normal, compiz runs smoothly

But this is only true for the first marco, if you then do a marco --replace and a compiz --replace, marco doesn't survive and there are no signs of unusual CPU load. It has been reported that the same is true for emerald.

confirming
for me the fix is. https://wiki.archlinux.org/index.php/MATE
ln -s /usr/lib/libgnutls.so /usr/lib/libgnutls.so.26

and adding killall marco to startup

the issue doesnt dissapear entirely tho. at some random point it keeps coming back.

@xpander69 in that wiki page, that fix is for caja, not for compiz/mate

There's a fix for the CPU issue already but I had an issue with memory leaks in regards to unity-window-decorator. I was able to get around this by modifying:

/desktop/mate/session/required_components/windowmanager/

You can simply set this to nothing and then continue to run the "compiz --replace" as a startup application. That way you don't have to kill marco because it never actually runs. It seems to have resolved the memory leak that I was seeing as a result of running marco before compiz.

[benpicco]

Or even better - replace marco with compiz in /desktop/mate/session/required_components/windowmanager/ so it will use compiz automatically.

[drakej]

I tried that but for some reason mate doesn't properly load compiz when set and results in missing window manager errors. Would be great if it could, maybe next update.

[benpicco]

This issue is still present.

Work around multi desktop environment friendly shell script for startup applications:
#!/bin/sh if [ 0pidof mate-session -gt 0 ]; then killall marco compiz --replace & fi
Note: in precise (and maybe other distros) you may need to go into CCSM and configure it before using compiz for to to be usable
you may need to run gtk-window-decorator --replace & to get title bars
Anyone how how to do get the these comments to use a the html tag pre?

Open /usr/share/app-install/desktop/compiz.desktop and change any references from GNOME to MATE and any references of metacity to marco. Then copy /usr/share/applications/marco.desktop to /usr/share/app-install/desktop.

This should work.

[GM-Script-Writer-62850]

the naming system seems to be different than that on my install of xubuntu 12.04

ls /usr/share/app-install/desktop | grep compiz
compizconfig-settings-manager:ccsm.desktop
compiz-core:compiz.desktop

ls /usr/share/app-install/desktop | grep wine
q4wine:q4wine.desktop
wine1.4:wine.desktop
winefish:winefish.desktop
winetricks:wine-winetricks.desktop

why do i have wine desktop files in here anyway when wine is not installed???

anyway i will give that a try with this different naming system

edit: metacity does not appear in this file, aborted will do on a test system i can afford to break
also would i change "X-GnomeWMSettingsLibrary=compiz" to "X-MateWMSettingsLibrary=compiz"

[Frannoe]

starting mateconf-editor and change:
/desktop/mate /session/required_components /windowmanager marco

to

/desktop/mate /session/required_components /windowmanager compiz

Finally create an application to start with the command:
compiz ccp

It works perfectly

[GM-Script-Writer-62850]

that works nicely Frannoe
now to get gtk-window-manager working right currently using this in a startup script
sleep 3; gtk-window-decorator --replace --metacity-theme "Ambiance"

Thank you very much!
