(This is a repost, but with link to source + binary this time).
I'm using CygWin XFree86 with a dual monitor setup and a single monitor
setup. In my experience there are, not surprisingly, more problems with
the dual monitor setup.
This made me think a bit about how multi-monitor CygWin XFree86 could
get more testing.
Is there any interest amongst CygWin XFree86 testers/developers in a
virtual device driver that will do the following?
- allow adding of any number of virtual video cards. E.g. test CygWin
XFree86 with 10 video cards? No problem! :-)
- the video cards are "visible" indirectly by using e.g. the
Accessibility->Magnifier
- resolution is currently fixed at ~4000x2000x32bit, but it could be
made configurable
- the virtual device driver works by allocating a RAM buffer where all
rendering takes place. Windows does all the rendering and it seems to be
feature complete. OpenGL works, though I wouldn't hold my breath for
DirectX apps.
The source code is currently collecting dust, and I'm sure I could
convince the owner to contribute it to the open source community if
there is enough interest.
