Arca Noae licenses source code for SNAP Graphics for OS/2

(1/3) > >>

Martin Iturbide:
Hi.

I'm very happy for this news.

SNAP is a video driver that I keep using till today on OS/2-eCS and this is a good news. I really hope to see this drive to came out.
But I'm hoping that later it can be improved in two things that sounds to be very basic for other OSes, but not for us.
1) The ability to switch resolution without rebooting.
2) The ability to connect a project/external monitor and that it will work without rebooting.

And I don't want to get greedy but I also want to dream away. I really hope that someday they also think to implement expanded desktops on OS/2 on modern video chipsets and that you can have several displays and select how it will be expanded or duplicated.

I think that one of the good things of Windows was to implement "OS Key + P" to switch the projection mode:



I wish Arca Noae good luck with this driver.

Regards

Maybe I'm misremembering but I thought that IBM attempted to implement this in the Warp 4 beta and it was just too hard to do in a non-buggy manner as the whole system has to readjust to the different resolution.

Fahrvenugen:
Yes, I seem to recall that switching resolutions without a reboot is something that PM does not support, and would take a major rewrite of various portions of PM to make it happen (not to mention that this might make various apps stop working).

I could be wrong, but if my memory is correct then it is unlikely to happen regardless of who has the rights to the driver.

But I too am encouraged by this news.  I also am one who continues to use SNAP, I find it works better then just about anything else out there for video.

RBRi:
Great news....
Hope we will see a continuous improvement done in small steps.

Years ago I had a discussion with an OS/2 user on an IRC channel (I think it was ten years ago). Aaaah found the ticket on SNAP...

 <Ltning> lou: some very early Trident drivers were able to change
resolution 'on-the-fly' in os2 2.x <Ltning> lou: I suppose they
incorporated so much of the GRE in their driver that it was possible
<Ltning> I still suspect IBM was very much involved with that driver -
judging from how the os2 support hotline kept telling me to get such a
card <MrWizard?> Trident also had HW panning and scrolling
<MrWizard?> virtual screen stuff <MrWizard?> POS card with great
drivers :-P

<lou> Ltning: that is even possible today <Ltning> lou: you mean PM
can be killed and restarted?? <Ltning> then why the HELL hasn't anyone
done that?? <lou> Ltning: yes. requires a bit of tweaking. seen
customers doing that.

But so far this has yet be confirmed what is written above if anybody has been able to get this to work.
