+You need to create Xorg configuration file and autostart script for setting the resolution.
+. Create Xorg configuration file ''/etc/X11/xorg.conf.d/10-ts050-fbdev-rotate.conf''.
+```txt
+Section "Device"
+    Identifier "Configured Video Device"
+    # Rotate off
+#   Option "Rotate" "off"
+    # Rotate Right / clockwise, 90 degrees
+    Option "Rotate" "CW"
+    # Rotate upside down, 180 degrees
+#   Option "Rotate" "UD"
+    # Rotate counter clockwise, 270 degrees
+#   Option "Rotate" "CCW"
+EndSection
+Section "InputClass"
+    Identifier "Coordinate Transformation Matrix"
+    MatchIsTouchscreen "on"
+    MatchProduct "EP0000M09"
+    MatchDriver "libinput"
+    # Rotate Right / clockwise, 90 degrees
+    Option "CalibrationMatrix" "0 1 0 -1 0 1 0 0 1"
+    # Rotate upside down, 180 degrees
+#   Option "CalibrationMatrix" "-1 0 1 0 -1 1 0 0 1"
+    # otate counter clockwise, 270 degrees
+#   Option "CalibrationMatrix" "0 -1 1 1 0 0 0 0 1"
+EndSection

+<WRAP info >
+  * The configuration above will rotate to landscape mode, you can also rotate to other modes, simply uncomment the mode you want.

+You can rotate the framebuffer console in two ways.
+  * System Node
+  * Configuration File
+<WRAP info >
+Framebuffer console rotation value:
+  * 0 - default value (landscape mode)
+  * 1 - rotate 90 degrees
+  * 2 - rotate 180 degrees
+  * 3 - rotate 270 degrees
+</WRAP>
+. Rotate via system node.
+  * Check the current configuration of the node. \\ ```shell
+$ cat /sys/class/graphics/fbcon/rotate
+
+```
+  * Modify the configuration to rotate the framebuffer(90 degrees). \\ ```sh
+$ echo 1 | sudo tee /sys/class/graphics/fbcon/rotate
+$ cat /sys/class/graphics/fbcon/rotate
+
+```
+  * Restore framebuffer console to the default setting. \\ ```shell
+$ echo 0 | sudo tee /sys/class/graphics/fbcon/rotate
+$ cat /sys/class/graphics/fbcon/rotate
+
+```
+<WRAP info >
+The modification will be lost after a power cycle, if you want to save it you can check the other way below.
+</WRAP>
+. Rotate via configuration file
+  * Check related configuration. \\ ```shell
+$ cat /boot/env.txt | grep "fb_rotate"
+fb_rotate=0
+```
+  * Change setting(rotate 90 degrees): \\ ```shell
+$ sudo vim /boot/env.txt
+fb_rotate=0 change to fb_rotate=1
+```
