Desktop resolution problem of jetson TX2

Hello everyone,

When set the resolution 1280x720(16:9) , the screen dislplay not well, the icon has stretch deformation. If set 1280x800(16:10), It’s ok. But no 1280x800 choice. How to resolve this problem? Thanks.

The first thing you’d want to do is see what the driver thinks of that mode, and to know what dmesg shows from the mode switch. To know about the driver, add Option "ModeDebug" somewhere in the Section "Device" of “/etc/X11/xorg.conf”:

Section "Device"
   Option "ModeDebug"
End Section

…then reboot. When in the GUI see what you get for “echo $DISPLAY” (probably “:0” or “:1”), and assuming it is “:0”, the log will be “/var/log/Xorg.0.log” (if “:1”, then it will be Xorg.1.log). Rename it with a .txt suffix and attach it to your post in this thread.

For dmesg, if you are using xrandr to switch mode, then first run “dmesg --follows”. When you run the xrandr to change mode, then more should be added to the dmesg…post what shows up.

Someone else may need to help with details, but that information will be needed first. Also, can we correctly assume the monitor is purely HDMI without any form of adapter?
