== 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
 
 
 
== 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
 
 
 
== Missing GLX_EXT_texture_from_pixmaps when trying to run Compiz Fusion on ATI ==
 
 
 
=== First solution ===
 
 
 
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 &
 
 
 
=== 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))
 
 
 
 
 
== 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 [http://wiki.compiz-fusion.org/Troubleshooting Compiz-Fusion Wiki] states: <i>"If you are using an Intel GMA card with AIGLX, you will need to start Compiz Fusion with LIBGL_ALWAYS_INDIRECT=1 appended.</i>"
 
 
 
== 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.
 
 
 
== 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
 
 
 
== 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
 
 
 
==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
 
 
 
==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
 
  File "/usr/lib/python2.5/site-packages/FusionIcon/interface.py", line 23, in <module>

    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
