Hello,

I'm currently trying to configure i3wm to work properly with my multiple
monitor set up. Yes, I am running a nVidia card and yes I have read "
http://i3wm.org/docs/multi-monitor.html";. I can enable xinerama in X11,
use --force-xinerama with i3 to get xinerama working.

However, I would much rather have separate X screens with Xinerama
disabled, each running their own i3 instance. In an attempt to try this, I
configured i3 to spawn on each of my DISPLAYs (:0.0 :0.1 :0.2) in my
".xinitrc" file. This sucessfully spawned i3 instances on each of my X
screens -- however I am experiencing input problems. Keyboard shortcuts
only seem to work on a single i3 instance. The other two i3 instances that
are spawned are unusable since one i3 instance catches all of the keyboard
events.

You may be wondering why someone would want Xinerama disabled -- well there
are very few games that support Xinerama and even if they do support
xinerama they will not display correctly with exotic monitor/resolution
configurations.

I use awesome in a similar way -- I spawn awesome on all three x screens
and whichever screen the cursor is on will receive keyboard input. I'm not
sure if this is something programmed within awesome or something within X,
but would something like this be a possibility for i3?

Regards,
Lukas Sabota
