KRDC is a remote desktop client for Linux that allows you to connect to Windows servers using RDP. It is commonly used on KDE based systems, but it also works on Ubuntu, Debian, Red Hat, Rocky, AlmaLinux and other distributions where KDE libraries are available.
Important: This guide was tested on Ubuntu 24.04 LTS using KRDC installed via Ubuntu App Center in the default Wayland session. Some steps and settings may differ slightly if you are using a different Linux distribution or installed KRDC using another method.
The appearance of KRDC may also vary depending on your Linux distribution, desktop environment, and system theme. The screenshots in this guide were taken on Ubuntu 24.04 LTS with dark mode enabled, so the interface may look slightly different on your system. However, the main sequence of steps should remain similar.
1. Install KRDC
In your desktop environment, you can install KRDC using your system software manager. In Ubuntu, you should open App Center, search for KRDC and then install it:
2. Connect to Windows Server via RDP
2.1. Initiate a new connection
Open KRDC and in the search bar enter your Windows server IP address. From the small dropdown meny select RDP. Then, press Enter.
2.2 Host Configuration
Host Configuration windows will appear. Here you should select these settings:
Resolution: Large 1920x1080 or set a fixed custom resolution
Scale window contents to match resolution: Disabled
Desktop scale factor: Custom (100)
Device scale factor: 100
Acceleration: Force RemoteFX
These settings prevent graphical corruption and black screen artifacts in full screen mode.
Click "Ok" to continue.
2.3 Enter server login details
When prompted, enter:
Username: Administrator or another Windows user
Domain: Your server hostname (you can find it in your client area under Service Details)
Password: Your Windows Administrator or another user password (you can find the administrator password in the client area Services ---> VPS ----> Manage ----> Login Details).
If a certificate warning appears, accept it to proceed (click "Continue"). Make sure to click 'Remember this certificate', otherwise this warning will appear each time.
3. Additional notes
After connecting, if you need Full Screen, press Ctrl Shift F on your keyboard or use the toolbar to enable it.
If the desktop looks incorrectly scaled or graphical glitches appear in full screen, recheck your connection settings in KRDC and ensure:
Scaling is set to 100 in both desktop device scale factors;
Acceleration is set to Force RemoteFX.
If the resolution is not correct, disconnect and open Host Configuration again.
Then, set a custom resolution that matches your monitor.
After the first successful connection, it will appear in the main KRDC window. Next time, right-click on the connection and then just press "Connect".
