Run without root window (so X apps appear on screen with Android apps)

Some X servers support a "rootless" mode (disabling the X root window). For example, on MacOS, fink can do this: http://www.finkproject.org/doc/x11/intro.php

Is something like this possible in Android? I can imagine trying to emulate it by creating multiple Android windows, one for each X window. But that might cause problems with some X applications.

Alternately, could it be done with an Android window having transparent areas (everywhere between X windows)? allowing other apps to show through? Mouse interaction with them would not work but at least you could see them.

This is not supported by XSDL, but you can resize XSDL window itself on select Samsung devices. On Mar 16, 2016 12:21 AM, "Warren Downs" [email protected] wrote:

I think, we need to port latest x.org from scratch. Without SDL, just use glamor to render screen directly. Glamor already supports gles2 and egl. Juet need to write surface creation code which would operate in rootless mode and event handler for it. I already made separate app for accelerared opengl, but XSDL seems absolute unuseful. It breeaks local tcp connections on vpn start (i checked with telnet: it is not android issue, but xsdl itself) It crashes on keyboard connect/disconnect. Seems to be fixed in last versions, but last version just crash at start. And it is catastrophicly slow :(

How would the inter-activity communication / multiple windows work?

@mittorn did you have any idea with this? one android window for one X window

Currently not possible.
