Everything should work right out of the box and very stable, as far as I can tell: Midi, printing etc. Most problems, that arose for me, had to do with wine and configuration.
If anything doesn't work, the developer is always concerned to make it run under linux/wine also.
What does not
Sometimes there are problems with sound, but probably they are wine or ubuntu-related. On my laptop there are some issues with the Control key , but I'm pretty sure that this has to do with wine (or ubuntu) also - I'm using there the alpha version of ubuntu 9.04.
What was not tested
Most things I notate I do with it under ubuntu / linux, and it should work without problems.
