Windows Remote Desktop is reasonably smooth over my limited home internet connection, even while using a 5120×2880 monitor. However, I set up an Ubuntu desktop machine in a data center and access it with xrdp, and the experience is extremely sluggish. Opening or resizing windows can take several seconds, screen redraws are slow, and normal desktop work feels frustratingly laggy. Is this mainly a limitation of xrdp, Linux desktop environments, or the very high resolution? Would another solution such as NoMachine, X2Go, Sunshine/Moonlight, or a different RDP setup perform better? I'm fairly new to Linux, so practical configuration advice would also be helpful.

For a full interactive desktop, NoMachine is probably the first alternative I’d try. It generally feels much more responsive than basic VNC or an older xrdp setup, and it supports useful features such as clipboard sharing and file transfers. X2Go is another solid choice, especially when bandwidth is limited, though it can work best with lightweight desktop environments.
RustDesk, Parsec, and similar tools are worth considering for occasional access, but they have different strengths. RustDesk is convenient for general remote support, while Parsec is optimized more for low-latency streaming. For a persistent Linux workstation, NoMachine or X2Go would be my starting points, followed by tuning xrdp and reducing the session resolution.
Before replacing xrdp, check the basics. Use a recent xrdp release, verify whether H.264 encoding and hardware acceleration are enabled, and make sure the connection can use UDP rather than being forced entirely through TCP. Also try a lower remote-session resolution and color depth. A 5K desktop contains a huge number of pixels, and transmitting or re-rendering all of that can overwhelm both the server and the connection.
The desktop environment matters too. Xorg-based sessions tend to be easier to run through xrdp than Wayland sessions, and a lighter environment can make a noticeable difference on a virtual server.
Sunshine with a Moonlight client can provide an exceptionally smooth experience because it streams the desktop as an efficiently encoded video feed. It’s often much better than traditional remote-desktop protocols for personal use, but the host needs enough CPU or GPU encoding capability. A 5120×2880 stream also requires considerable bandwidth, so you may need to reduce the resolution or bitrate.
This approach is excellent when the host has GPU support. A data-center VM may not have an encoder available, so check that before expecting the same performance as a dedicated desktop.
If you only need a few graphical applications, don’t run a complete desktop session. SSH with X11 forwarding can be surprisingly responsive for terminals, admin tools, and simple applications, assuming latency is low. For regular GUI work, though, xrdp, NoMachine, or X2Go will usually be more practical.
X2Go has been reliable for me for years, and it handles compression well. It’s a particularly good fit for ordinary office and administration work rather than graphics-heavy applications.
