Hi nvidia
I faced this problem,
I install vnc and working very well except if i unplugged the dp cable the connecion is freezed so i check the forum, and found can use dummy display so I modified the " xorg.conf file " with :
Copyright (c) 2011-2013 NVIDIA CORPORATION. All Rights Reserved.
This is the minimal configuration necessary to use the Tegra driver.
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.
Section “Module”
Disable “dri”
SubSection “extmod”
Option “omit xfree86-dga”
EndSubSection
EndSection
Section “Device”
Identifier “Tegra0”
Driver “nvidia”
Allow X server to be started even if no display devices are connected.
Option "AllowEmptyInitialConfiguration" "true"
EndSection
Section “Monitor”
Identifier “Configured Monitor”
HorizSync 31.5-48.5
VertRefresh 50-70
EndSection
Section “Screen”
Identifier “Default Screen”
Monitor “Configured Monitor”
Device “Tegra0”
DefaultDepth 24
SubSection “Display”
Depth 24
Modes “1920x1080”
EndSubSection
EndSection
After rebooting i got nvidia logo with “no hdmi signal from your device” THEN “go standby mode”
I checked a lot, but i want solution without flashing jetson is there any way to rever xorg.conf ?
