Why is Alpine Linux so small and what are the tradeoffs?

Alpine uses musl libc instead of glibc and busybox instead of GNU coreutils, resulting in a tiny base image (~5MB). Tradeoffs include some software compatibility issues with glibc-dependent apps and no systemd (uses OpenRC).

How do you run XRDP on Alpine without systemd?

Alpine uses OpenRC which doesn't work well in WSL. Start XRDP manually with "sudo /usr/sbin/xrdp && sudo /usr/sbin/xrdp-sesman" or create a startup script. You can also add these commands to your shell profile.

What package manager does Alpine use?

Alpine uses apk (Alpine Package Keeper). Common commands: "apk update" to refresh repos, "apk add package" to install, "apk del package" to remove. Packages are minimal by default, so you may need to install more dependencies manually.

Alpine Linux Desktop on WSL2: Lightweight XRDP Setup Guide

Alpine Linux is the speed demon of this series. With musl libc instead of glibc and a minimal base, it boots faster and uses less RAM than any other distro tested. The trade-off is more manual setup—OCI images are barebones, OpenRC doesn't play nice with WSL, and some packages need extra configuration. But if you want the fastest possible Linux desktop on WSL2, Alpine delivers.

Why Alpine on WSL2?

Tiny footprint—minimal base image, fast boots
musl libc—smaller, simpler C library
apk package manager—fast and efficient
Security-focused—used heavily in containers
Resource efficient—more RAM for your actual work

After testing while my 5090 was being RMA'd (charred power cable saga), Alpine was noticeably snappier than the others—especially for basic desktop tasks.

Prerequisites

Windows 10 (version 2004+) or Windows 11
WSL2 installed and working
Alpine Linux from OCI image or WSL UI

Installing Alpine

Alpine is available via OCI container images. Install through WSL UI which can import OCI images directly.

Critical: OCI Images Are Minimal

Alpine OCI images boot as root only with almost nothing installed—no sudo, no regular user, no OpenRC. You'll build everything up from scratch.

Step 1: Create a User

bash

# Install sudo
apk add sudo

# Create user with wheel group
adduser -D -s /bin/sh -G wheel yourname
echo "yourname:yourpassword" | chpasswd

# Enable wheel group sudo
echo "%wheel ALL=(ALL) NOPASSWD: ALL" >> /etc/sudoers

# Set as default WSL user
cat > /etc/wsl.conf << 'EOF'
[user]
default=yourname
EOF

Restart WSL:

powershell

wsl --terminate alpine

Step 2: Install XFCE, XRDP, and Xorg

Critical: Unlike other distros, Alpine doesn't pull in xorg-server as a dependency. You must install it explicitly:

bash

sudo apk add xfce4 xrdp xorgxrdp xorg-server

Without xorg-server, XRDP fails with "No such file or directory" for /usr/libexec/Xorg.

Step 3: Configure XRDP

Change the Port

bash

sudo sed -i 's/^port=3389/port=3390/' /etc/xrdp/xrdp.ini

Step 4: Create xinitrc

Alpine uses .xinitrc like Arch:

bash

echo "exec startxfce4" > ~/.xinitrc
chmod +x ~/.xinitrc

Step 5: Start XRDP (OpenRC Workaround)

OpenRC doesn't work in WSL because the system wasn't booted by it. You'll see errors like:

You are attempting to run an openrc service on a system which openrc did not boot.

Start XRDP directly instead:

bash

sudo /usr/sbin/xrdp-sesman
sudo /usr/sbin/xrdp

For automatic startup, add a boot command to /etc/wsl.conf:

bash

sudo tee /etc/wsl.conf << 'EOF'
[user]
default=yourname

[boot]
command=/usr/sbin/xrdp-sesman; /usr/sbin/xrdp
EOF

Step 6: Connect

Open Remote Desktop Connection on Windows (Win+R, type mstsc)
Enter localhost:3390
Log in with your Alpine username and password

Installing Chromium

Alpine doesn't have Google Chrome, but Chromium works well:

bash

# Install Chromium and D-Bus (required)
sudo apk add chromium dbus dbus-x11

# Start D-Bus daemon
sudo mkdir -p /run/dbus
sudo dbus-daemon --system --fork

Important: GPU acceleration causes blank screens over RDP. Launch with:

bash

chromium-browser --disable-gpu --disable-software-rasterizer

From Windows terminal to XRDP desktop:

bash

# Find your display number
ps aux | grep Xorg
# Look for :10, :11, etc.

# Launch on that display
DISPLAY=:11 chromium-browser --disable-gpu --disable-software-rasterizer

Quick Reference

bash

# As root initially
apk add sudo
adduser -D -s /bin/sh -G wheel yourname
echo "yourname:password" | chpasswd
echo "%wheel ALL=(ALL) NOPASSWD: ALL" >> /etc/sudoers
cat > /etc/wsl.conf << 'EOF'
[user]
default=yourname
[boot]
command=/usr/sbin/xrdp-sesman; /usr/sbin/xrdp
EOF
# Then: wsl --terminate alpine

# As regular user
sudo apk add xfce4 xrdp xorgxrdp xorg-server
sudo sed -i 's/^port=3389/port=3390/' /etc/xrdp/xrdp.ini
echo "exec startxfce4" > ~/.xinitrc
chmod +x ~/.xinitrc

# Start manually (or restart WSL to use boot command)
sudo /usr/sbin/xrdp-sesman
sudo /usr/sbin/xrdp

# Connect: mstsc → localhost:3390

Alpine-Specific Gotchas

Issue	Solution
Running as root only	Create user manually, install sudo
OpenRC commands fail	Use direct `/usr/sbin/xrdp` or boot command
"No such file /usr/libexec/Xorg"	Install `xorg-server` explicitly
Chromium blank screen	Use `--disable-gpu --disable-software-rasterizer`
Chromium D-Bus errors	Install `dbus dbus-x11`, start daemon
Uses ash not bash	Install bash if needed: `apk add bash`

Why OpenRC Doesn't Work

WSL uses its own init system, not OpenRC. When you try rc-service:

You are attempting to run an openrc service on a
system which openrc did not boot.

You can workaround with touch /run/openrc/softlevel, but dependency issues (networking service) usually follow. The boot command approach is cleaner.
