??? example "Using Waveshare screen that is installed with LCD-show"
??? example "Raspberry Pi using kernel cmdline"
To set screen orientation when in console mode, you will need to edit the kernel command-line
to pass the required orientation to the system.
```bash
cd LCD-show/
sudo ./LCD43-show 270 lite
sudo nano /boot/firmware/cmdline.txt
```

To rotate by 90 degrees clockwise, add the following to the cmdline, making sure everything is on the same line, do not add any carriage returns. Possible rotation values are 0, 90, 180 and 270.
To rotate by 90 degrees clockwise, add the following to the cmdline, making sure everything is on the same line,
do not add any carriage returns. Possible rotation values are 0, 90, 180 and 270.
For example a DSI screen:
```bash
video=DSI-1:800x480@60,rotate=90
```
Other values can be "HDMI-0" "HDMI-1, "DPI-0" etc
To find the identifier on a terminal run:
```bash
DISPLAY=:0 xrandr
```
it will output something like:
```bash
Screen 0: minimum 320 x 200, current 1024 x 600, maximum 8192 x 8192
HDMI-1 connected primary 1024x600+0+0 (normal left inverted right x axis y axis) 800mm x 450mm
```
in this case the identifier is HDMI-1 and a simple cmdline arg would be something like:
```bash
video=HDMI-1:1024x600@60
```
To apply changes do a reboot:
```bash
sudo reboot
