• Edit and change the value of the transform variable in your selected output section of the weston.ini Weston configuration file located in /etc/xdg/weston/weston.ini

vi /etc/xdg/weston/weston.ini
...
# LVDS-1 connector
[output]
name=LVDS-1
mode=preferred
transform=rotate-90
...
# DSI-1 connector
[output]
name=DSI-1
mode=preferred
...

• Restart Weston

systemctl restart weston-graphical-session

Information

Use the command modetest: to get the exact DRM connector name for the field name= (DRM connector name examples: DSI-1, DPI-1, LVDS-1, HDMI-A-1...). to get the supported DRM modes for the field mode= (DRM mode examples: preferred, 720x480, ...). Read weston-drm manpage for more details.

Warning

Make sure there are no extra spaces at the beginning or end of any lines in the weston.ini file. Changing screen orientation may cause performance changes during graphics use cases.
