Screen Orientation

Depending on your needs, photOS can also be configured to show the images in portrait mode.

The following commands are executed on the device, so login into it:

> ssh root@photos-xxxxxxxx
> mount -o remount,rw /boot

Find the corresponding rotation in the official Raspberry Pi documentation and add it to /boot/config.txt (e.g. 90 degree clockwise):

.
.
.
display_hdmi_rotate=1

Thereafter, reboot the device:

> reboot

config.txt is located on the first partition, if you want to change it directly on the SD-Card with your computer.
