Thanks to Merovius for doing a proof of concept on this one and
being a driving force behind the idea.
Using RandR instead of Xinerama means that we are now able to use
the full potential of the modern way of configuring screens. That
means, i3 now has an idea of the outputs your graphic driver
provides, which allowed us to get rid of the ugly way of detecting
changes in the screen configuration which we used before. Now, your
workspaces should not be confused when changing output modes anymore.
Also, instead of having ugly heuristics to assign your workspaces
to (the screen at position X or the second screen in the list of
screens) you will be able to just specify an output name.
As this change basically touches everything, you should be prepared
for bugs. Please test and report them!
Please note that rdesktop’s -g workarea option will not work on
64-bit systems at the moment because of a bug in rdesktop (see the
rdesktop-devel mailing list).
This fixes many problems we were having with a dynamically growing
array because of the realloc (pointers inside the area which was
allocated were no longer valid as soon as the realloc moved the
memory to another address).
Again, this is a rather big change, so expect problems and enable
core-dumps.
As the workspaces are now created dynamically, we cannot rely on
the workspaces to be there when we need them without creating them.
On the other hand, this eliminates the case that there are no workspaces
to assign to a new screen, because now we can just create one.
The following new directives have been implemented for the configuration
file:
new_container <default|stacking|tabbed>
new_container stack-limit <cols|rows> <value>
Note that they require using the new lexer/parser, which you can
do by passing -l to i3 when starting.
Warning: This is not yet thoroughly tested, so be prepared to
encounter some segfaults. Please enable logging and coredumps,
so we can fix bugs quickly.
This is necessary because otherwise the window into which the
pointer is warped still is at its old position, so that the pointer
will effectively be warped onto the wrong screen in case of moving
a window to another screen.
Thanks to Mikael for bringing it to my mind. This change introduces
two new color classes, client.urgent and bar.urgent. By default,
urgent clients are drawn in red (colors by Atsutane).
Please test this! Plug in screens, unplug them, use your video projector,
change resolutions, etc.
To use the assignments, use the following syntax:
workspace <number> [screen <screen>] [name]
Where screen can be one of:
<number> (It is not provided that these numbers stay constant, so use with care)
<x>x<y> (Coordinates where the screen starts, so 1280 will be fine to match the
screen right of the main screen if your main screen is 1280 pixels
width. However, 1281 will not match)
<x>
x<y>
Some examples follow:
workspace 1 screen 0
workspace 1 screen 1
workspace 1 screen 1280x0
workspace 2 screen 1280
workspace 3 screen x0
workspace 3 screen 1 www
workspace 4 screen 0 mail
