Hi, I vaguely remembered (might have dreamed of it) that MorphOS had the ability to use RDP or VNC as a video card, basically boot up with internal support for no monitor, keyboard or mouse physically connected to the MorphOS box - but, all my efforts to find it in the OS - no luck.

Is there such a feature, if so where is it? thanks, Julian

The Virtual monitor driver is found in MOSSYS:Storage/Monitors. If you copy it to SYS:Devs/Monitors the Virtual modes will be available on every boot. You will then be able to configure your Screens with them. Then you'll need VNCServer - Just download it from Morphos Files and configure it according to your needs.

many thanks for that, is there any benefits in doing this versus just running VNC? is it to reclaim resources that would usually be taken up by having two screens?

Yes, it's about reclaiming a specific hardware resource. Its advantage over just running VNC is that it "allows starting of MorphOS without a graphics card". AFAIK it was mainly done for Efika 5200B which has only one PCI slot so that this slot can then be used for a PCI card other than GFX card. But of course you can use it with any other system running MorphOS as well.

You can even use the virtual graphic board as a secondary screen with MorphOS.

I demoed the stuff at the AmigaMeeting 2011 and there is even a video, where I moved the secondary screen to an ipad.

At the end at 50:45 I show how to due this.

You opened the screen on another device using VNC, but you did not move it. It's not the same because no AmigaOS or successor has screen movement implemented. I hoped one could at least move window from one screen to another using drag and drop instead of opening the context menu and click through the MUI preferences 5 times to flip the window to another screen. Maybe MUI will support it one day.

Here this takes just 2 clicks, one click for opening the menu and a second click for selecting the target screen from the list.

.. and it is possible to save that screen selection, so an application opens on that screen all the time.

And it behaves like having two screens next to each other, so you can move the mouse out if the screen and it appears on the secondary (or third) screen.

The only difference between windows and other systems is that it is not one huge screen with increased dimensions, where you can drag windows half the way over.

an interesting thing: if there is the Virtual monitor file in MOSSYS:Devs/Monitors, I have a green output video using SDL games (with powersdl.library 14.0)
Removing It, SDL is OK.

SDL V14 requires a 32 bit screen mode, or some games look wrong.

@Geit
It's 24bit the screenmode (using ATI 92xx), but if there is Virtual file in MOSSYS:/Devs/Monitors , the SDL games have a "green" output video , if removed the Virtual file from MOSSYS:/Devs/Monitors ed rebooted all SDL games are ok

(It's not the green problem with SDL games when screenmode is 16bit for exemple)

That is interesting. Too bad I can not take a look into it now (SDL).

You need to edit a mode inside the virtual monitor icon and SDL looks ok again.

Just enable the MODE=1024x768@16 line and SDL looks fine again on non virtual screens.

No clue what is going wrong here, but its clearly a bug in virtual gfx driver or SDL. More likly SDL, but who knows.
