It occurred to me that multiple Linux domains can all share the same framebuffer. Just treat domain swaps as VT swap events. You could even set the different domains up so that something like Ctrl-Alt-Shift-1, 2, 3 jumps between domains. dom0 would catch the key stroke, send the current domain a VT save event, switch to the new domain and send it a VT restore. This assumes that all domains have direct access to the video hardware. This scheme will probably work for multiple basic Xservers one in each domain, but it will not work for multiple OpenGL or composite users since they will stomp on each other's use of video RAM. -- Jon Smirl jonsmirl@xxxxxxxxx _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
