I need to reduce the amount of weight I carry because of a shoulder injury, so taking my full work laptop everywhere is becoming difficult. Ideally, I'd like to use a lightweight terminal—or a device already available at another location—to connect securely to a single work environment containing my software, configurations, VPN access, SSH keys, vaults, and other tools. I'd prefer not to maintain several separate environments. SSH handles much of my work, but I sometimes need full GUI applications as well. What setup provides the best balance of security, responsiveness, reliability, and ease of maintenance?

A practical setup is to leave the main laptop or a dedicated workstation powered on and connect to it through a private WireGuard or Tailscale network. Use SSH for command-line work and a remote desktop protocol such as RDP, VNC, or a more responsive alternative for GUI applications. Keeping the host inaccessible from the public internet and requiring strong authentication makes this much safer than exposing remote desktop directly.
A lightweight tablet or laptop connecting to a jump host is a good compromise, but avoid using unknown or unmanaged computers for sensitive work. Keep credentials protected with passphrases and MFA, use a bastion or jump host for production systems, and restrict access to a private overlay network. Remote GUI sessions can work well over a low-latency connection, but hardware or biometric MFA may not pass through cleanly, so that should be tested before relying on the setup.
If you want a hardware-based solution, an IP KVM can let you control the computer remotely, including its boot screen and login process. Some compact KVM devices provide keyboard, video, and mouse over the network, though latency depends heavily on the network connection and the device. For ordinary desktop work, software remote access will usually feel better; a KVM is more useful when you need recovery access or want to control the entire physical machine.
How responsive are these KVM devices for normal GUI use? I’d mainly need terminals and a few desktop tools rather than gaming or video editing.
I use a small inexpensive laptop with a fully encrypted removable Linux installation, plus a WireGuard mesh and SSH access to my systems. That gives me a lightweight travel setup without duplicating all my credentials and configurations. If the laptop is lost, the storage is encrypted, and replacing the hardware is relatively painless. A phone or tablet with a keyboard can work for basic tasks, but the screen and input become limiting quickly.
That’s close to what I had in mind: one environment that stays configured, with a lightweight device acting only as the terminal. My main concern is making the GUI responsive enough for occasional desktop applications.
