I have to agree with wizard, I have installed the most recent 64 bit distro of Ubuntu with little success. I also went back to Fedora, which seems to have the best options. BDI had a really nice base behind it, I cant find the distro I had before and my cd was scratched so it wouldnt install the cad program. Mind this is a dual boot system, so all of my cnc is done in windows but no hurt in experimenting. Mach 3 is great, after the battle of learning the curve.
I also strongly agree with Wizard that LINUX WILL NEVER EVER EVER be like windows, thats the point. Keep in mind 64 bit technology can strongly change the way Linux behaves in the future. The 64 bit of ubuntu sucks PERIOD. Wizard, here's to you for your clarifications
