HiDPI and 4K Displays Guide

Introduction

If you have a screen with a very high dots-per-inch (DPI), the interface, particularly the status bar at the top, may appear very small. This guide will help you adjust the display settings to make the interface more comfortable to use.

Adjusting DPI

To change the DPI (dots-per-inch) of your display, you can use the xrandr command. Open a terminal and run the following command, replacing 96 with your desired DPI value:

Terminal window 
															
																

																	

																		xrandr
																		
																		--dpi
																		
																		96

After running the command, you may need to refresh the window manager. You can do this by pressing Super + Shift + R.

Making DPI Changes Persistent

To make the DPI changes persistent after reboot, you can edit the ~/.xprofile file. Open the file in a text editor and locate the command similar to the one you used to adjust the DPI. Modify the DPI value as needed and save the file.

Display Configuration

For a more advanced display configuration, you can use the displayselect script. This script provides a user interface for detecting and selecting all connected displays. It allows you to configure multi-monitor setups and adjust display arrangements easily.

Displayselect Script

Terminal window 
															
																

																	

																		displayselect

load the script to a file named displayselect in a directory included in your system

This script will provide you with options to configure your display setup conveniently.

Remember to run the script without closing the terminal window to execute it successfully. Or by pressing Mod+ F3
