Remmina, alternative Linux à UltraVNC

Mis à jour le 23 octobre 2026

Notre avis

Remmina is a solid Linux alternative for most UltraVNC use‑cases. It can connect to any standard VNC server, including UltraVNC, and adds built‑in SSH tunnelling for encryption. For occasional remote support or personal remote‑desktop work it offers a simple UI, clipboard sync and multi‑monitor handling. Power users who rely on UltraVNC‑specific extensions (e.g., custom authentication plugins or proprietary file‑transfer protocol) will miss those features, but for the core tasks Remmina works well.

Ce qui fonctionne pareil

Both act as VNC clients to view and control remote desktops
Support for multi‑monitor and fullscreen scaling
Clipboard sharing between local and remote machines
Ability to transfer files (Remmina via built‑in SFTP/SSH tunnel, UltraVNC via its own file‑transfer channel)
Can be run from the system tray for quick access

Ce qui change

Remmina relies on SSH tunnelling for encryption; UltraVNC has its own built‑in encryption options
UltraVNC includes a Windows‑only server component; Remmina is client‑only on Linux
UltraVNC offers proprietary plugins (e.g., video driver capture) that Remmina does not support
Remmina’s file transfer uses SFTP/SSH, not the UltraVNC proprietary file‑transfer protocol
UltraVNC can run as a Windows service for unattended access; Remmina has no server side on Linux

Ouvrir vos fichiers UltraVNC

Remmina does not understand UltraVNC's .uvnc configuration files directly. You can manually recreate the connection settings in Remmina, but there is no automated import or export tool. If you have saved passwords or custom plugins in UltraVNC, those will need to be re‑configured in Remmina.

Passer de UltraVNC à Remmina, étape par étape

Install Remmina from your distro repository or via Flathub.
Create a new VNC connection profile and enter the UltraVNC server's address and port.
Enable "Use SSH tunnel" and provide the remote machine's SSH credentials for encryption.
Set the desired screen resolution, multi‑monitor mode, and clipboard options.
Test the connection; adjust scaling or keyboard shortcuts as needed.
Save the profile for future use and optionally add it to your desktop's quick‑launch bar.
