[edit] Compiz ( or Compiz-Fusion ) Troubleshooting

[edit] KDE fallback

If you are using KDE and something is not right, for example you don’t see borders for your window, you can switch back to kwin with this command:

 kwin --replace

[edit] GNOME fallback

If you are using GNOME and something is not right, for example you don’t see borders for your window, you can switch back to metacity with this command:

metacity --replace

[edit] Missing GLX_EXT_texture_from_pixmaps when trying to run Compiz Fusion on ATI

[edit] First solution

http://bbs.archlinux.org/viewtopic.php?id=50073 If you run into the following error when trying to run Compiz Fusion on an ATI card:

Missing GLX_EXT_texture_from_pixmap

This is because Compiz Fusion's binary was compiled against Mesa's OpenGL library rather than ATI's OpenGL library (which is what you are using). Re-install libgl-dri (yes you will have to uninstall fglrx temporarily) to get Mesa's OpenGL library.

copy the library into a directory to keep it because ATI's drivers will over write it.

mkdir /lib/mesa
cp /usr/lib/libGL.so.1.2 /lib/mesa

Once you have it copied, you can reinstall your fglrx drivers (It should have been removed when you installed libgl-dri). Now you can start Compiz Fusion using the following example syntax:

LD_PRELOAD=/lib/mesa/libGL.so.1.2 compiz --replace &

[edit] Second solution

An other problem could arise with GLX_EXT_texture_from_pixmap, it is possible that the card could only render it indirectly, then you have to pass the option to your libgl like that :

 LIBGL_ALWAYS_INDIRECT=1 compiz --replace ccp &

(Workaround tested on the following card : ATI Technologies Inc Radeon R250 [Mobility FireGL 9000] (rev 02))

[edit] Missing GLX_EXT_texture_from_pixmaps when trying to run Compiz Fusion on Intel chip

First off, check that you're using the intel driver as opposed to i810. Then, run the following command to run compiz (must use this every time.).

LIBGL_ALWAYS_INDIRECT=true compiz --replace --sm-disable ccp &

If you then don't have borders, run

emerald --replace

As at 17-Oct-07 the Compiz-Fusion Wiki states: "If you are using an Intel GMA card with AIGLX, you will need to start Compiz Fusion with LIBGL_ALWAYS_INDIRECT=1 appended."

[edit] Fusion-Icon showing up as red "X" in status bar, icon missing in menus

The GTK icon cache needs to be refreshed (hopefully this will be added in the .install file of the package). Run the following command:

# gtk-update-icon-cache -f /usr/share/icons/hicolor

if this fails try installing the package hicolor-icon-theme:

# pacman -S hicolor-icon-theme

Fixed with new community package.

[edit] Compiz starts, but no effects are visible

If you have installed compiz-decorator-gtk: 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=/usr/share/gconf/schemas/compiz-decorator-gtk.schemas

[edit] Compiz starts, but gtk-window-decorator does not

It is a configuration problem for gconf and gconfd. I solved it by removing ".gconf" dir in my home, but I'm using KDE. If you are using Gnome you should enter your ".gconf" directory and remove all compiz keys. You'll loose your Compiz settings tough! Finally exec as user:

 gconftool-2 --install-schema-file=/usr/share/gconf/schemas/compiz-decorator-gtk.schemas

[edit] Compiz appears to start, but there are no window borders

When you run fusion-icon from commandline, you get output like this:

* Detected Session: gnome
* Searching for installed applications...
* NVIDIA on Xorg detected, exporting: __GL_YIELD=NOTHING
* Using the GTK Interface
* Metacity is already running
* Setting window manager to Compiz
... executing: compiz --replace --sm-disable --ignore-desktop-hints ccp

compiz (core) - Warn: No GLXFBConfig for depth 32
compiz (core) - Warn: No GLXFBConfig for depth 32

All you need to do is edit your /etc/X11/xorg.conf and find the "Depth" directive inside the "Screen" section; change all occurences of this value to 24. This occured to me with my colour depth set to 16; but also happens when it is set to 32.

You may also try adding Option "AddARGBGLXVisuals" "True" & Option "DisableGLXRootClipping" "True" to your "Screen" section if you are using the Nvidia binary driver. (Radeon, and the open 'nv' driver will not work with this option as far as I can tell.)

[edit] Blank screen on resume from suspend-to-ram using the Nvidia binary drivers

If you receive a blank screen with a responsive cursor upon resume, try disabling sync to vblank:

gconftool -s /apps/compiz/general/screen0/options/sync_to_vblank-t boolean false

[edit] fusion-icon doesn't start

If you get an output like this from the command line:

[andy@andylaptop ~]$ fusion-icon
 * Detected Session: gnome
 * Searching for installed applications...
Traceback (most recent call last):
  File "/usr/bin/fusion-icon", line 57, in <module>
    from FusionIcon.interface import choose_interface

    mkdir(name, mode)
OSError: [Errno 13] Permission denied: '/home/andy/.config/compiz'

the problem is with the permission on ~/.config/compiz. You have set the owner of a folder in your area as root. To change this, run (as root)

chown <username> /home/<username>/.config/compiz

[edit] Video Playback

If you can't see video playback on Compiz, change the video output to something like OpenGL. In VLC you go to Settings->Video->Output modules and tick the advanced options box.

[edit] CCSM Locale Errors

If you get locale errors when starting ccsm, make sure you have set your locale in /etc/rc.conf and in /etc/locale.gen, and then run (as root),

locale-gen

You might have to try a couple different locales for your language to get it to work properly.

[edit] Second option

Your second option is to fix Python 2.5 - If one of your errors points you to a line in locale.py - jot down the line number and switch user to a root account.

Open "/usr/lib/python2.5/locale.py" in the editor of your choice as your root account and surf on down to the line number you jotted down earlier (as of this writing it is 476) and change:

   return _setlocale(category, locale)

   return _setlocale(category, None)

[edit] Poor Performance on Intel cards

This works on the Intel 945GM, but has not been tested on other Intel cards. For smooth compositing effects you will need to add these lines into your Device section:

Option      "DRI"                    "True"
Option      "NoDDC"                  "True"
Option      "XAANoOffscreenPixmaps"  "True"
Option      "EnablePageFlip"         "True"
Option      "RenderAccel"            "True"
Option      "AccelMethod"            "XAA"

And ensure that you have the following somewhere:

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