Now we host the Cairo Compositing Manager, so you can download it whenever you want. And of course you can install it on Lubuntu 12.04 (even its version is older than the Precise Pangolin, it worked fine). I’ve updated the Tools page and posted links for both i386 and amd64 architectures. Enjoy!
After a revieweing and tuning process (by the one who never sleeps, Julien Lavergne) the additional tools for Lubuntu has been updated. There are changes in version numbers (lubuntu-control-center 0.3 and lxkeymap 0.3) and wheight (recompiled and reduced unneeded size). Now the tools are from the official Lubuntu Desktop PPA (ensuring compatibility). Jump to the tools section and download while hot!
