Monitor - bakkeby/dusk GitHub Wiki

The Monitor topic is specifically about different displays / screens / monitors.

For a general definition of what a monitor is in the context of the window manager refer to the Concepts page.

The window manager is configured to use the Xinerama libraries in config.mk and can automatically detect configured screen outputs and their resolutions.

One of the easiest ways to configure screen outputs is via the RandR X server extension using the xrandr tool.

Without arguments it will list the current configuration of screen outputs.

$ xrandr

For each connected output the supported resolution modes will be printed.

Alternatively for a graphical tool to arrange monitors the arandr will produce xrandr commands.

The xrandr commands can later be put in shell scripts so that the multi-monitor layout can be restored when the computer starts. Refer to the autostart page for more information.

List of functions that are specific to multi-monitor setups.

In a single monitor setup these functions are redundant.

In a dual monitor setup the direction is irrelevant as the monitors will wrap around.

In a 3+ monitor setup these may or may not work as you might expect.

In terms of arguments in principle a positive value is intended to select the monitor on the right and a negative argument is intended to select the monitor on the left.

It is worth noting that this works based on the monitor index.

That is, if the current monitor index is 1 then:

• a negative value (going left) will bring you to monitor index 0 and
• a positive value (going right) will bring you to monitor index 2

It is also worth noting that when using a Xinerama setup the order in which the screens are returned depends on a few things, but typically the monitor marked as being the primary will be returned first ending up as monitor 0. This also means that any subsequent monitors will end up as monitor 1 and 2.

If the direction is reversed for you then flipping the + and - signs for the keybindings may help.

Alternatively you should be able to influence the order in which the monitors are returned by Xinerama by making changes to the xrandr command that sets up the screens.

Another options would be to enable the SortScreens functionality which sorts the monitors left to right before assigning indexes. This has an impact on bar configuration and workspace rules, however, as monitor 0 will be the leftmost monitor rather than the primary.
