Compiz/Troubleshooting

Compiz starts, but no window-decorations, or unable to move/resize windows

Update compiz and check if >=metacity-2.16

$ gconftool-2 -R /apps/compiz/plugins | grep decoration

/apps/compiz/plugins/decoration:
 /apps/compiz/plugins/decoration/allscreens:
  /apps/compiz/plugins/decoration/allscreens/options:

If you don't get a similar response, use gconf-editor to add decoration to the plugins

$ gconf-editor

Select apps / compiz / general / allscreens / options

edit "active_plugins"

add "decoration", "move", and "resize" to the list

Compiz starts, but no effects are visible

Check if GConf schema was correctly installed:

gconftool-2 -R /apps/compiz/plugins | grep plugins

make sure that all plugins are listed (not only fade!). If not, try to install compiz schema manually (do this as normal user, not as root!!!):

gconftool-2 --install-schema-file=/etc/gconf/schemas/compiz.schemas

CCSM don't use changed settings

Intro: I used the gentoo-xeffects.org Overlay and there Compize-Fusion-Wiki-Installation. After following the instructions, my CCSM don't keep his settings. --ChrisJumper

The solution is to emerge fusion-icon!

1. Unmask the following Packages, so add them in /etc/portage/packages.keywords

x11-apps/fusion-icon **
dev-python/PyQt4 ~x86
dev-python/sip ~x86

2.

# emerge fusion-icon

3. Optional: If you use Gnome, add fusion-icon in your autorun

$ gnome-session-propperties

3a. Klick the Add-Button in the first tap.

Name: fusion-icon
Command: fusion-icon

Flash 7.0 content crashes in Firefox

If you notice that Firefox crashes upon navigation to a site with Flash content but the problem is gone when you comment out the Option "Composite Enable", try adding this:

XLIB_SKIP_ARGB_VISUALS=1

But be aware that this option can introduce problems with other programs, such as Beryl/Emerald. In my case, there were no window decorations visible until I removed this option.

Segmentation Fault occurs when running compizrc

If Segmentation Fault occurs when running compizrc, try adding:

unset XLIB_SKIP_ARGB_VISUALS 

above the line /usr/bin/compiz

If you still get a Segmentation Fault, and used Compiz from Portage, try to re emerge with dbus enabled

USE="dbus" emerge compiz 

JAVA program does not show contents

If java programs do not show contents, export this to fix.

export AWT_TOOLKIT=MToolkit

For detail, here is its upstream and this will be fixed in future version. http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6429775

Swsusp2 with Compiz and aiglx

Suspending with compiz never worked well for me under xgl but I've finally got it working under AIGLX. To suspend, I made a little script that would replace compiz with metacity prior to hibernation.

This assumes you have a working swsusp2 kernel already installed. Create the file /usr/bin/prepare and /usr/bin/resume

  nano /usr/bin/prepare

killall gnome-window-decorator &
killall compiz &
metacity --replace gconf &

  nano /usr/bin/resume

sudo killall gnome-window-decorator &
sudo killall metacity &
DISPLAY=:0 /usr/bin/compizrc &

Then make the files executable

  chmod +x /usr/bin/prepare

  chmod +x /usr/bin/resume

I needed to add killall to my sudo list otherwise I was unable to kill metacity if i hibernated as a user.

  visudo

Add the following entry to the file that opens

  (insert user name here) ALL = NOPASSWD: /usr/bin/killall

Note: this is a major security risk and should only be done if you are confident that you are the only person who will use "sudo killall". Once done, execute /usr/bin/prepare just prior to hibernating. Metacity will replace compiz and hibernate successfully. Upon resume, execute /usr/bin/resume, and compiz will restore properly. You can have this done automatically if you add the following entries to your /etc/hibernate/hibernate.conf file:

### misclaunch
OnSuspend 20 /usr/bin/prepare &
OnResume  20 /usr/bin/resume &
