Tornare indietro con KDE
Se si sta utilizzando KDE e qualcosa non va per il verso giusto, ad esempio non si riescono a visualizzare i bordi delle finestre, si può tornare a kwin con questo comando:
Tornare indietro con GNOME
Se si sta utilizzando GNOME e qualcosa non va per il verso giusto, ad esempio non si riescono a visualizzare i bordi delle finestre, si può tornare a metacity con questo comando:
Tornare indietro con XFCE
Se si sta utilizzando XFCE e qualcosa non va per il verso giusto, ad esempio non si riescono a visualizzare i bordi delle finestre, si può tornare a metacity con questo comando:
Con schede video ATI (prima soluzione)
http://bbs.archlinux.org/viewtopic.php?id=50073 Se si ottiene il seguente errore mentre si cerca di avviare Compiz Fusion con una scheda video ATI:
Ciò è dovuto al fatto che il file binario di Compiz Fusion è stato compilato per le librerie OpenGL di Mesa piuttosto che quelle OpenGL di ATI (che sono quelle che si stanno utilizzando). Si reinstalli quindi libgl-dri (sì, è necessario momentaneamente disinstallare anche fglrx) per ottenere le librerie OpenGL dei driver Mesa.
Copiare quindi le librerie in una cartella per mantenerle dal momento che i driver ATI andranno a sovrascriversi ad esse.
mkdir /lib/mesa cp /usr/lib/libGL.so.1.2 /lib/mesa
Una volta copiate, è possibile reinstallare i propri driver fglrx (dovrebbero essere stati rimossi quando si è installato il pacchetto libgl-dri). Ora si può avviare Compiz Fusion utilizzando la seguente sintassi d'esempio:
LD_PRELOAD=/lib/mesa/libGL.so.1.2 compiz --replace &
Con schede video ATI (seconda soluzione)
Un altro problema può sorgere riguardo GLX_EXT_texture_from_pixmap, è infatti possibile che la scheda video sia in grado di renderle solamente in maniera indiretta, in questo caso è necessario passare un'opzione come questa al proprio libgl:
LIBGL_ALWAYS_INDIRECT=1 compiz --replace ccp &
(Soluzione verificata sulle seguenti schede video: ATI Technologies Inc Radeon R250 [Mobility FireGL 9000] (rev 02))
Con i chip Intel
Innanzitutto, assicurarsi di utilizzare i driver intel piuttosto che gli i810. Quindi, lanciare il seguente comando per avviare compiz (dovrà essere fatto ogni volta).
LIBGL_ALWAYS_INDIRECT=true compiz --replace --sm-disable ccp &
Se non si riesce a visualizzare i bordi, lanciare
Dal 17-Ott-07 il Compiz-Fusion Wiki dichiara: "Se si sta utilizzando una scheda video Intel GMA con AIGLX, è necessario avviare Compiz Fusion con l'aggiunta di LIBGL_ALWAYS_INDIRECT=1."
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!!!):
Note: Compiz basic plugins are not enabled by default. You should enable "Move Window", "Resize Window", and "Window decoration" plugins in settings manager from fusion-icon to have a usable window manager.
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. This will erase your compiz settings, so be sure to reconfigure. Finally exec as user:
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 compiz (core) - Warn: No GLXFBConfig for depth 32 compiz (core) - Warn: No GLXFBConfig for depth 32 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.) If you used any other Options elsewhere in xorg.conf to get compiz working and still have no luck, try commenting them out and using only the aformentioned ARGBGLXVisuals and GLXRootClipping Options.
Note: Check that "Window decoration", "Move" and "Resize" plugins are enabled with Compiz Settings Manager or gconf-editor.
With gconf-editor you can easly enable "Window decoration", "Move" and "Resize" plugins.
Navigate to apps/compiz/general/allscreens/options
Add/Edit "active_plugins" Key (Name: active_plugins, Type: List, List type: String).
Add "decoration", "move", and "resize" to the list.
Another way to fix this:
- Open ccsm (run it as a command from the terminal, or start it from the system menu).
- Find windows decoration and make sure it is enabled.
- Now click on it, to edit the options.
- If the entry behind command is empty, put the value gtk-window-decorator there.
- Alternatives are kde-window-decorator and emerald
- Click Back and Close
- If all went well, the borders should appear.
Compiz starts and borders appear, but windows won't move
Be sure you have the "Move Window" plugin installed and enabled in the compiz settings manager.
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> import start File "/usr/lib/python2.5/site-packages/FusionIcon/start.py", line 36, in <module> config.check() File "/usr/lib/python2.5/site-packages/FusionIcon/util.py", line 362, in check os.makedirs(self.config_folder) File "/usr/lib/python2.5/os.py", line 172, in makedirs 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
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.
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),
You might have to try a couple different locales for your language to get it to work properly.
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)
Poor Performance on Intel cards
Template:Box 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
However, you can find better settings in the compiz official wiki.
Choppy animations, even though everything configured correctly
If everything is configured correctly but you still have poor performance on some effects, try disabling CCSM->General Options->Display Settings->"Detect Refresh Rate" and instead choose a value manually. Tested on both nvidia and intel chips. Can work wonders.
Alternatively, if your chip is nvidia and you are experiencing an inadequate refresh rate with "Detect Refresh Rate" enabled in Compiz, it's likely due to an option called DynamicTwinView being enabled by default which plays a factor in accurately reporting the maximum refresh rate that your card and display support. You can disable DynamicTwinView by adding the following line to the "Device" or "Screen" section of your xorg.conf file, and then restarting your computer:
Option "DynamicTwinView" "False"
Doing so will allow XrandR to accurately report the refresh rate to anything that detects it, including Compiz. You should be able to leave "Detect Refresh Rate" enabled and get excellent performance. Once again, this only applies to nvidia chips.
Fix Gnome Screenshot
To re-enable gnome-screenshot (the default behavior caused by hitting Template:Keypress) simply go to Settings Manager>Commands and map 'gnome-screenshot' to the 'PrtScn' key. This is advantageous because you can also use the Compiz-Fusion 'Screenshot' plugin at the same time since the action that enables it is <Super>Button1 thereby giving you two methods to do a screen capture (one of which gives a full screen capture in a single keystroke).
Get GNOME Workspace Switcher work with Compiz-Fusion
In older versions of Compiz, the Gnome Workspace Switcher applet would actually work with Compiz-Fusion (i.e. rotate cube/move plane etc.), but recent versions seem not to. This is due to a new feature introduced in Compiz, which allows real seperate workspaces. For example, if you have a desktop plane with four planes, and have four desktops enabled in Gnome, it sums up to a total of 16 different workspaces. Currently, there is no animation associated with "real" workspace changing. To get the Workspace Switcher work, do the following:
In GConf, set the following options:
/apps/compiz/general/screen0/options/number_of_desktops = 1 /apps/compiz/general/screen0/options/hsize = 4 (this is an example) /apps/compiz/general/screen0/options/vsize = 1 (this is an example)
Slow resizing of windows with compiz/emerald and ATI videocards
I was surprised to see that ATI has a poor performance when resizing windows in emerald. I googled around and found out that the problem is with the normal setting in the resize window plugin. To fix this simple change the "Default Resize Mode" setting in the plugin settings to anything other than Normal then, you'll resize windows quickly again.
Brief explanations about the resize options:
Rectangle: Renders a rectangle that represents the new size of the window while resizing. The window is resized after you stop dragging. While resizing, the window is still visible in the background at the original size.
Outline: Same as the rectangle mode but there is an outline instead of a filled rectangle.
Stretch: The window is stretched to the size of the dragging rectangle and doesn't actually repaint until you are finished dragging.
Screen flicks with NVIDIA card
For fixing it, create /etc/modprobe.d/nvidia.conf file and add line:
options nvidia NVreg_RegistryDwords="PerfLevelSrc=0x2222"
Fix Custom Cursor Theme on Gnome 2.30
Create or edit /usr/share/icons/default/index.theme for default, or per user (non-root) ~/.icons/default/index.theme, and add this lines:
[Icon Theme] #Name=foo Name=foo #Inherits=foo Inherits=foo [Desktop Entry] Name[en_US]=index.theme
"Foo" is the name of the cursor theme.
Screen artifacts on Firefox / Thunderbird
Some users noticed a strange behavior with AMD/ATI Catalyst drivers starting from 10.6 release. Artifacts are visible mainly with Mozilla applications, where the GUI shows black spots of variable size. This is caused by different 2D acceleration tecnique introduced with Catalyst 10.6. The problem can be fixed following the troubleshooting steps in the ATI Catalyst page
Setting the window manager back to Metacity after uninstall
Removing compiz with pacman does not set your window manager back to metacity. This can result in no window borders being drawn, an inability to minimize, and an inability to change the focus. To change it back, run the command "gconf-editor" in the terminal (install it if you don't have it already). Use this to set the value of the key /desktop/gnome/session/required_components/window_manager from "compiz" to "metacity". Log out and back in for this change to take effect.
Desktop wallpaper and xorg-server 1.9
Currently the wallpaper plugin of compiz-fusion doesn't act correctly with xorg-server 1.9. to fix it refer to this forum page.
