how to rotate screen on ubuntu server 

Steps for Command-Line Server without GUI:

If you only have a command-line interface, you’ll likely need to configure the terminal display through framebuffer settings or the kernel command line.

1. Edit GRUB Configuration: Open the GRUB configuration file:

   bash

   CopyEdit

   sudo nano /etc/default/grub

2. Add a Framebuffer Rotation Option: Modify or append the GRUB_CMDLINE_LINUX_DEFAULT line:

   bash

   CopyEdit

   GRUB_CMDLINE_LINUX_DEFAULT="quiet splash fbcon=rotate:1"

   Use the following values for fbcon=rotate:X:

   • 0: Normal
   • 1: 90 degrees
   • 2: 180 degrees
   • 3: 270 degrees

3. Update GRUB and Reboot: Update the GRUB configuration:

   bash

   CopyEdit

   sudo update-grub

   Reboot the server:

   bash

   CopyEdit

   sudo reboot

After rebooting, your screen should appear rotated based on the fbcon setting.
