Last night I setup Lubuntu 12.04 on my Stormtrooper (B&W G3 w/G4 500 MHz, 1 GB RAM) and it runs beautifully. With OS X my 400 MHz Sawtooth is normally a bit faster than this machine even with a 100 MHz faster CPU because of the faster memory controller in the Sawtooth. This is not the case with Lubuntu at all, which would be due to how lightweight LXDE is. OS X has such a beefy GUI in comparison so increased memory speed will really show a difference with it because of that.
Another item worthy of note is that of the 5 video cards I have used in all my testing Lubuntu likes a Radeon 7000 PCI the best. In my 400 MHz Sawtooth I have tried AGP Radeon 7500, 9000, 9800 and a Geforce 6200. None of them work quite as well as the 7000 PCI and this must be due to it finding an R100 specific Radeon driver vs. the generic ones all the other cards are assigned. The Geforce 6200 only works when it wants to which is not often. Linux on all architectures has a history of being sketchy with Nvidia GPU.
I have tried every version of Linux available for PowerPC and Lubuntu is my favourite by far. I would put Debian Squeeze and Mint about tied for second. Just a couple days ago I was running Squeeze on the Stormtrooper and within 30 hours I decided I wanted Lubuntu instead. It’s all about preference and since Dan at PPC Luddite already focuses mostly on Debian and Mint it would only make sense for me to cover other distros so as not to be redundant. I will do my best to be a voice for PowerPC Lubuntu.
In terms of the Ubuntu family only Lubuntu gets my personal approval. I have tried every single one and while they are all complete enough to be usable, only Lubuntu is lightweight enough to match and even surpass Debian performance. Some people think that installing LXDE in Ubuntu will produce the same OS which is not the case at all. The lightweight ideology of Lubuntu goes much deeper than the GUI. Lubuntu has the balance that any good OS needs which is great performance combined with full capability. Anything you need that isn’t built in can easily be found and installed in Synaptic.
Install guide coming soon
I have now done approx. 8-9 Lubuntu installs on three machines so I have become quite fluent at it. In the next few days I will post a full Lubuntu install guide since I have had a lot of emails and a few comments asking for help. I will take you from downloading and burning the iso right through to having it fully setup for use.
