RE: Can multiple remote sessions be run simultaneously under v4.2.0?


Victor,

Yes, what you describe is supported... but there are some rough edges that
you will encounter.  The idea is that you start one X Server that runs
multiple screens, each connected to a different host.  The primary problem
that you will encounter is that sometimes the Windows mouse cursor is not
hidden or revealed correctly.

An example command line would be:

XWin -screen 0 1024 768 -query host1 -screen 1 1024 768 -query host2 -screen
2 640 480 -query host3

Unfortunately, you have to specify the width and height of each window (1024
width by 768 height, etc.) when using the -screen parameter.  All
screen-specific parameters that follow one -screen parameter will apply to
that screen only, until another -screen paramter is encountered.  Thus the
first -query parameter applies to screen 0, the second -query applies to
screen 1, etc.  The window will be made as large as will fit on the screen
if you specify a screen size that is as large or larger than the current
graphics mode (i.e. if you are running at 1024x768 then a 1024 768 or larger
screen parameter will create a window slightly smaller than 1024 768 to
account for the Start menu; increasing the parameter to 1280 1024 will not
create a larger window).

Hope that helps,

Harold
