Now supports upside-down screen modes too. Guess who's in a silly mood? 
But does it rotate the mouse pointer yet?
/me hands you a SYS"XOS_SpriteOp",36,256,mypointer%,1,0,0,0,0
There, done. Where's the problem?
This doesn't work too fantastically if apps start changing the pointer shape. Sit on SpriteV and intercept the call, I say  |

If one can have different displays on the monitors (games etc) then presumably you can have different resolutions/colours?
And the monitors have independent screens, ie separate frame-buffers?
I remember seeing an arcade game once which had 3 screens. Very cool. |

Somebody has to update Elite* so that you can see out of a different window with each monitor. 
* or Dark Matter... |

* or Dark Matter... You can already have multiple camera views on the same screen. No doubt as soon as the Geminus API is made public, you'll be able to stick those views on the other monitors too
Hmm, how would VSync events work? Would all monitors have to be at the same frequency, or is some kind of callback system used so that when a monitor VSyncs the program using that monitor will be notified, allowing multiple programs to wait at once? |

No doubt as soon as the Geminus API is made public, you'll be able to stick those views on the other monitors too "Me test, me test!" 
Hmm, how would VSync events work? Well, here's your chance to influence the design because I haven't finalised that yet....
I had in mind to leave the existing event-based API driven by just the primary monitor, and provide a couple of SWIs in the Geminus module to register a handler for screen x that will be called whenever a VSync arrives from that screen.
Remember that, although the screens will normally be running at the same frequency, they are still asynchronous (there's no genlocking between
cards). |

Or could you try to synchronise them by changing between modes with different frame-rates? |

Why yes, having an Iyonix to test it on could be useful

That sounds like the most sensible idea. For example, all that the Dark Matter VSync handler would need to do is swap the two screen banks over (Providing the new one has valid data in it), and flag the old one as being ready for redrawing by the main thread.
Remember that, although the screens will normally be running at the same frequency, they are still asynchronous (there's no genlocking between cards). What? You haven't worked out a way to do a software genlock yet? For shame! |

No, they don't have to, but they usually will, because most users will have the same monitor and MDF for each card.

What? You haven't worked out a way to do a software genlock yet? For shame! In my naive youth (as opposed to my naive adulthood) I tried to genlock two Electrons into one monitor (combining the RGB outputs) by running the clock signal from one Electron across to t'other so that their ULAs would be in sync.
Didn't work very well, the pictures never quite lined-up
What I can't remember for the life of me, is why the hell I wanted to do that in the first place?! |

Oh, that was it. I was going to rival Silicon Graphics by bolting 2000 Electrons together and getting them all to render Mode 0 graphics in parallel!
(Hey, with 32 Electrons, you could have 32bpp x 640 x 256, that's almost good enough to render DVD fields.... ) |

It's great but the only problem is it doesn't quite do all pointers, so the hand and finger in oregano are strange :) It kind of ruins the effect! |

Yes, does now. 90, 180 or 270 degrees, take your pick
I have one screen in portrait, and one landscape, both software-rotated 90 degrees anti-clockwise, so that dragging a window off the right edge of the 2nd screen makes it appear at the bottom of the 1st screen! I think I need to a break.....
Edit: Yup, if you can't write a sentence, what's the code gonna be like?

So can you have one screen portrait, one landscape and still have it all the right way up yet? |

How about different resolutions on each screen? |

They are. For you to see the whole of your desktop (which must be rectangular) you need all the heights to be the same (if they're side-by-side) - not that Geminus cares if you want to lose your windows - so...
I just created a mode with 1280 x 1024 landscape & 768 x 1024 portrait side-by-side.... ie. left screen unrotated, right screen rotated 270 degrees. Pointer rotated on the latter, unrotated on the former, so it's always the right way up.
The result: 2048 (1280 + 768 ) x 1024
Pointless? Well, if they're different monitor types, eg. your dusty old AKF60 that you've dragged out of retirement, then you'll probably want to run it at a different resolution to your LCD.

I meant having two monitors, both the same way up, at different resolutions, not neccesarily same height/width |

?!
OK, I've just created a mode that's 2304 x 1024 with no rotations.
The left 1280 x 1024 is on the first LCD
The rightmost 1024 x 768 is on the 2nd.
Leaving... a rectangle of 1024 x 256 above the right screen that you can't see, so if you put windows up there you won't be able to find em again.
Does that qualify as sufficiently stupid?
Sheesh, what more do you want?! |

The first release will probably reject modes with holes (or at least issue a warning) , and maybe I'll incorporate them in a later version. We've already been asked to restrict the iconbar to a single screen, and this too will require more work with the Kernel/WindowManager. Geminus is just a fancy screen driver at the moment. |

Out of interest, are you actually doing this in conjunction with castle/whoever or are you just sort of patching (or planning to) the windowmanager etc? |
