I installed it a few weeks ago out of curiosity and was able to get the NVIDIA drivers installed without any problem so that I could play with LG. It's fun to look at and play with but is seriously unstable. It lasts about 10 minutes and then all the pretty tricks stop working. I did manage to get some ordinary programmes working (e.g. kopete) from the CLI but that in itself was hit and miss as the keyboard sometimes would not function with it. Someone likened it to the way Vista and Apple were going - that put me right off

As it is only a prototype "proof of concept" application, stability is likely to be miissing. LG3D isn't even in alpha stage yet, so I'm not surprised. I've used it a few times (I'm actually using the Slax-based LG3D-livecd to type this) and had fun playing with it. It is highly recommended that you have a very good GPU (preferably nVidia), a fast processor, and a lot of RAM to run it smoothly. It runs decently on my Dell Dimension 4550 (2.5 GHz P4, 1 GB RAM, 256 MB GeForce 7800 GS AGP 4x video card), though it isn't 100% smooth, it is very usable for me.
Again, it's still a pre-alpha prototype. Compiz-Fusion is still buggy as well in many respects. But that's the beauty of open-source - you can fix and expand on work as you please.
