The C compiler will handle (void) as "no arguments" and () as "variadic
function" (equivalent to (...)) which might lead to subtle errors, such
as the one which was fixed with commit 0ea64ae4.
Add --force-xinerama when starting i3 to use Xinerama instead of RandR.
This should *ONLY* be done if you have no other choice (nvidia’s
binary driver uses twinview and does not expose the monitor information
through RandR).
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!
Before this fix, you could go upwards and select the screen which
was at the rightmost because it also was the one topmost (if all
screen’s top position is equal).
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
Thanks to psychoschlumpf for the hint. Having comments in the headers
makes it easier to get the big picture when not being interested in the
source.
The doxygen file extracts as much as it can into HTML files. Please note
that this is not official/supported documentation, but rather being nice
to people who have to/want to use doxygen (I don’t).
Let me paste the header of the doxygen file:
You can use this file with doxygen to create a pseudo-documentation
automatically from source. doxygen-comments are not used very extensively
in i3, mostly for the reason that it clutters the source code and has no
real use (doxygen’s output looks really ugly).
So, if you want to use it, here you go. This is however not a supported
document, and I recommend you have a look at the docs/ folder or at
http://i3.zekjur.net/ for more, real documentation.
