When no screens are found, the system defaults to a "virtual desktop", with a 640x480 resolution. For most users using one remote machine with one Tegra board it maybe sufficient to only change the default resolution of the virtual monitor of a headless system. For that you simply have to add a section "Screen" to your /etc/X11/xorg.conf and choose a resolution (Virtual 800 480)
Append at tail of /etc/X11/xorg.conf
Code: Select all
Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Default Device"
SubSection "Display"
Depth 24
Virtual 800 480
EndSubSection
EndSection
