There is no Linux kernel support for VGA Shield. We should write our own driver to draw. And it's old analog VGA with 18-bit (6 bit for channel) color... I dislike it.

Perhaps we might think again about the idea of using slave RPi instead :)

Hi guys,

ok if a driver is a problem for VGA Shield, can you try to include synergy code in your wtware img -> https://github.com/symless/synergy/ for sharing mouse and keyboard.
So we should use 2 separate RPi connected on HDMI monitors and share keyboard and mouse.

I think this should be awesome!! :D

Thank you so much.

Why do not buy x86 hardware for dual monitor configurations?

So no support for dual monitor in the near future I understand ?

Hi multi monitor support would be really nice
maybe you can integrate this usb vga adapter into your software:

as it's described here:

USB-VGA at your link costs $30. Add a bit more and buy x86 with two onboard video outputs. Onboard video at x86 will be many times faster than USB video at raspberry.

Which x86 model? Any should work. It's better to prefer models that are available on market for at least half a year.

Hi,
I would would have tried to configure my raspberry this way
https://www.novaspirit.com/2015/12/31/l ... pberry-pi/

For a dual monitor purpose using this https://www.amazon.com/gp/product/B00AB ... WD6W7N3SUQ

Unfortunately, it seems that bash commands have been cut to basics for security and prevents me from doing needed commands.
Someone already tried this ? Is there any way to do it with WTware ?
I'd really enjoy to test it on WTware instead of going back on Raspbian/Ubuntu... as it's a damn great product that, except concerning dual screen, matches perfectly my needs!
Thanks.

It's old USB 2.0 displaylink in video. Not interesting, because AFAIK is not manufactured anymore.

And there are no raspberry drivers for new USB 3.0 displaylink. Kick displaylink so they published their sources or release driver for Raspberry.
