I've played with a project built with Lazarus on most distributions (Suse, Ubuntu, Kubuntu, Fedora, Freespire, SLED, Mandriva, Zenwalk) , both x86 and x86_64. My one comment is that I've never been able to get the program fonts looking decent in gnome, never had a problem with KDE. If anyone has comments on a good looking Lazarus with gnome I'd appreciate them.
