First of all, navigate your browser over to: http://www.slackbuilds.org & run a search for "compiz," under version 12.2. Your first result will be the "compiz-bcop" slackbuild. Select it, which will show you a quick description of the package, and the suggested build order of all compiz packages:
Suggested build order:
3. compizconfig-backend-kconfig (optional)
4. compizconfig-backend-gconf (optional)
7. simple-ccsm (optional)
9. compiz-fusion-plugins-extra (optional)
10. compiz-fusion-plugins-unsupported (optional)
11. emerald (optional)
12. emerald-themes (optional)
13. fusion-icon (optional)
Now, download it. If you're unfamiliar with SlackBuilds, they're actually quite simple:
- Find which SlackBuild you'd like to download. In this case, it's the "compiz-bcop" SlackBuild. Please note that SlackBuilds do not contain the application's source, this is a separate download.
- Download "compiz-bcop.tar.gz," "compiz-bcop-0.7.8.tar.gz," (or other appropriate version) and optionally, the "compiz-bcop.tar.gz.asc" file.
- (Optional) If you chose to download the .asc file, you can verify the integrity of your SlackBuild by using the command gpg --verify compiz-bcop.tar.gz.asc
- Extract the SlackBuild with tar -zxvf compiz-bcop.tar.gz
- Move the source file, "compiz-bcop-0.7.8.tar.gz" into the newly extracted compiz-bcop directory, and extract this file too: tar -zxvf compiz-bcop-0.7.8.tar.gz
- Now all that's left to do is to run a quick root command of: su -c "./compiz-bcop.SlackBuild" or sudo ./compiz-bcop.SlackBuild
- You'll get some verbose build & other messages, which ultimately lead to a package created somewhere on your hard drive (in my case, which I believe is the default, the package created is /tmp/compiz-bcop-0.7.8-i486-1_SBo.tgz).
- Run a quick su -c "installpkg /tmp/compiz-bcop-0.7.8-i486-1_SBo.tgz" or sudo installpkg /tmp/compiz-bcop-0.7.8-i486-1_SBo.tgz to install the package.
Now, being my guide is for NVIDIA video cards, I'm unable to give much direction on other cards. To set up your card, head over to the Compiz Fusion Wiki: http://wiki.compiz-fusion.org/Hardware/NVIDIA and follow the steps for your appropriate driver version.
My /etc/X11/xorg.conf file's "Screen" section ended up look as such to get my extremely outdated GeForce MX 440 working:
# Allows GLX to work with composite.
Option "AllowGLXWithComposite" "True"
# Improves performance, enabled by default on driver versions >=1.0-9746
Option "RenderAccel" "True"
# Always force Hsync & Vsync regardless of the mode.
Option "UseFBDev" "True"
# I believe this was necessary to get window borders working as well. Please correct me if wrong.
Option "AddARGBVisuals" "True"
# Improves performance. Currently incompatible with SLI and MultiGPU modes. As of nvidia driver version 100.14.09, it has been enabled by default.
Option "DamageEvents" "True"
# Use the following option with caution as it may not work on all systems.
Option "UseEvents" "False"
# Use the following option with caution as it may not work on all systems, especially with 6 series GeForce cards (it is known to cause freezes with compiz) but give it a try because it helps performance. It can also break Xinerama.
Option "BackingStore" "True"
# Necessary to make window borders visible with nvidia driver versions prior to 100.xx.
Option "AddARGBGLXVisuals" "True"
NOTE: This will more than likely be different for your card, but these options work well with GeForce MX 440's :).
The next step will be to configure nvidia-settings to load your configuration at Xfce's start. To do this, I wrote a very simple bash script:
# Simple script to load NVIDIA settings on Xfce start.
Save this to ~/.init_nvidia, make make the file executable with the command: chmod +x ~/.init_nvidia and add it to your Xfce Settings->Sessions & Startup->Application Autostart tab.
Next time your restart your Xfce session, your NVIDIA settings will be loaded by default.
The next step is where I got tricked up, and want to document for anyone else who might be having issues. I attempted running the command compiz --replace to replace xfwm4 with compiz, but it seemed as if the two were litterally fighting over managing my windows, getting stuck in an endless loop of switching back & forth between themselves. After tinkering with this issue for hours, I found the simplest solution to RTFM. I found the solution on (ha) Arch Linux's Wiki (http://wiki.archlinux.org/index.php/Compiz --using fusion icon, method 2). The steps are very simple, but only work for the current user:
Edit ~/.config/xfce4-session/xfce4-session.rc and add the following to the bottom of the file:
Comment out Client0_Command=xfwm4 if it exists.
This should cause compiz to be loaded instead of xfwm4,
though this didn't seem to work properly without a few extra steps.
To prevent the default session from being overwritten add or change
the [General] section to:
Now save the file.
Back in Xfce Settings->Sessions and Startup->Application Autostart->Add a startup entry for the command fusion-icon
Close Xfce & remove all current sessions with rm -rf ~/.cache/sessions
Have fun :).
