1. Rotate the screen
There are two methods, one is the command line and the other is the graphical interface. Only the command line is covered here because of its simplicity.
xrandr -o left #向左旋转90度，用于横屏转竖屏
xrandr -o right #向右旋转90度
xrandr -o inverted #上下翻转
xrandr -o normal #正常显示
2. Permanently rotate the screen
By adding a line at the end of the 55gnome-session_gnomerc file, take the horizontal screen to vertical screen as an example.
$ sudo vim /etc/X11/Xsession.d/55gnome-session_gnomerc
Add at the end of the file
xrandr --output Virtual1 --rotate left
Save and exit
3. Possible problems
When bloggers are testing on Jetson tx2, they will find that step 2 is completed, and the screen is still wrong after restarting tx2. The solution is as follows: use the
graphical interface to modify the screen orientation, and then restart.
Settings (upper right corner of the graphical interface)->system settings->Displays->Rotation select Counterclockwise
