Renoise is an excellent tracker-based DAW with Linux support (you still have to find Linux-compatible VSTs though). It changed the way I write music.
EDIT: I know there are FOSS trackers like MilkyTracker. If you want an alternative, I can recommend it, even though it doesn't offer the same amount of features as Renoise (e.g. VST or effect support).
