I have tried it on Fedora 17 and on Fedora 19.
Fedora might maybe have some kind of problem with the concept of a "system tray", which seems to be a mac and/or windows concept.
However, it might be the case that more grandmas use windows or mac than use various types of Linux? (Is Android a type of Linux?) so maybe that is okay?
What I could access of it worked, but without any apparent way to make its "system tray icon" actually appear on my screen I was unable to properly use it because for some reason or lack of reason its main menu is in or popped up from the system tray icon. The main windows that appear for example when you first fire it up and it walks you through creating an account and so on has no way to get to the main menu.
I also had problems when I used "ssh -X" to ssh to the Fedora 19 box I built it on and installed it on from my graphics workstation where all the GUI stuff of any X-windows applications I run on various boxes should display. (The graphics workstation is basically just my desktop box that runs nothing itself ideally and instead merely serves as a graphical display terminal from which to run various apps on various boxes.)
When I ran Moneychanger directly from the screen and keyboard and mouse that were directly attached to the Fedora 19 box, Moneychanger fired up okay, but when I used ssh -X from my desktop box, which is still stuck with Fedora 17, the app popped up (on my Fedora 17 box's X-windows display) an error popup saying it could not find any support for a system tray.
So it looked like Moneychanger did think that Fedora 19 itself directly, using its own graphics card to drive its own local X-windows display, did have system tray support, as it did not pop up that error in that situation. But in the real world real use case of having the application run on an application-server box with its graphical display being on a graphics server (X-windows server) on the user's desk, the support for system tray could not be found.
FellowTraveler basically just says Fedora must be using a broken windowing system or something.
#fedora and #gnome type channels on Freenode never responded at all to any inquiries as to what is a system tray and whether gnome (the windowing system) even has such a thing, nor on whether system tray icons are or are not intended to be able to appear on the end-user's remote graphics server (graphical display, graphical terminal, X-windows server) or are deliberately restricted to only working on displays that are directly driven by the graphics card that is in the same machine that the application itself is run on.
I have problems running more machines to test this currently as all my circuit breakers are full almost to popping due to all the mining gear mining, I have all my machines turned off to free up electrical capacity for mining gear. But, I now have put Fedora 19 on a laptop so should now be able to again try to find what the system tray problem is and whether Fedora has such a tray and if not whether I can get one and install it or what.
(Possibly the machines I initially tried with might have broken X-windows installs or broken gnome3 windowing managers or something; the laptop is a fresh clean install so should let me at least find out if the problem is built into Fedora ab initio or was just something my specific old machines might have broken something over the years in the course of updating through several Fedora versions instead of using clean fresh installs from scratch.)
Also, Moneychanger cannot be built on default Fedora 17 lately, because the QT user-interface-editor they now use to create its user-interface is too new for the QT that comes with Fedora 17 to use. The QT that comes with Fedora 19 can build it just fine though.
