-### Step 11.13 — Install Ubuntu in VM 101
+### Step 11.13 — Disable Wayland, force Xorg
 
-**VM 101 (Desktop):** Start the VM, open the console, and work through the
-Ubuntu Desktop installer. Use `vm101` as the hostname. The desktop installer
-is graphical — click through the screens. When prompted for storage, install
-only to the 64GB OS disk; leave the data drives untouched.
+Ubuntu 24.04 defaults to Wayland. WinApps file sharing (`\\tsclient\home`)
+breaks under Wayland due to FreeRDP limitations — tsclient mounts as empty.
+Force Xorg system-wide with one command:
 
-**VM 102 (Server):** Repeat steps 11.9–11.10. Use `vm102` as the hostname.
+```bash
+ssh ubuntu@192.168.1.XXX
 
-During the storage step in each VM: install Ubuntu only on the small OS disk.
-Leave the large data drives untouched — they are for you to configure later.
+# Uncomment WaylandEnable=false in GDM config
+sudo sed -i 's/#WaylandEnable=false/WaylandEnable=false/' /etc/gdm3/custom.conf
+
+# Verify the line is now active (should print: WaylandEnable=false)
+grep WaylandEnable /etc/gdm3/custom.conf
+
+# Restart the display manager to apply
+sudo systemctl restart gdm3
+```
+
+After GDM restarts, log back in. Verify Xorg is active:
+
+```bash
+echo $XDG_SESSION_TYPE   # should print: x11
+```
+
+> **Why this matters beyond WinApps:** Wayland also has issues with some GPU
+> passthrough configurations, screen sharing tools, and remote desktop clients.
+> Xorg is the more stable choice for a server-side desktop running inside a VM.

+### Step 11.14 — Install Ubuntu in VM 101
+
+Start VM 101, open the console, and work through the Ubuntu Desktop installer.
+Use `vm101` as the hostname. When prompted for storage, install only to the
+64 GiB OS disk — leave the data drives untouched.
+
+After first login, disable Wayland on VM 101 as well (same command as Step 11.13):
+
+```bash
+sudo sed -i 's/#WaylandEnable=false/WaylandEnable=false/' /etc/gdm3/custom.conf
+sudo systemctl restart gdm3
+```
+
+**VM 102 (Windows 11):** Boot from the Windows 11 ISO, work through the
+installer. Use `windows-sync` as the hostname. Install to the 128 GiB OS disk.
+After install, format the dedicated Sync.com data drive as NTFS in Disk
+Management, then install the Sync.com desktop client and point it at that drive.
