# This is an optimized configuration for Xorg for the Toradex Tegra based
# Colibri and Apalis modules
#
# In order to disable unneeded monitor outputs, use Option "Ignore" "true"
# (in the monitor section). By defining a prefered resolution mode one
# can choose a prefered mode for all monitors. However, this mode is only
# used if the monitor reports it as being supported (through EDID).
#
# Please refer to the xorg.conf man page for more configuration
# options provided by the X server, including display-related options
# provided by RandR 1.2 and higher.
# Disable extensions not useful on Tegra.

# VirtualDesktop indicates which virtual desktops should be used by X.
# X will use the specified virtual desktop *and* the next one. In
# order for an external app to share a display with the X server, it
# needs to use the same virtual desktop. Valid values are integers 0
# (default) or 1.
# Option "VirtualDesktop" "1"
# OverlayDepth is a 32-bit integer which is used to control overlay
# stacking order. The overlay with the lowest depth is in front of
# all others. This value has meaning only when multiple overlays are
# present on a display.
# Option "OverlayDepth" "255"
# OverlayCombineMode determines how the X overlay is combined with the
# overlay behind it during scanout. Available modes are: Opaque
# (default), SourceAlphaBlend, and PremultSourceAlphaBlend. This
# value has meaning only when an external process has created a
# display which is behind the X server.
# Option "OverlayCombineMode" "PremultSourceAlphaBlend"
# ARGBHWCursor controls whether the X driver uses an overlay to
# display 32-bit "true-color" cursors, or whether such cursors are
# emulated in software. Valid values are "true" (default) to enable
# hardware cursors, and "false" to disable them.
