Dell Wyse 3040

This is a interesting little fanless cherry-trail thin client.

Specs

• Intel Atom x5-Z8350 (4 core, 4 threads, 64-bit, Cherry Trail)
  • Supports Virtualization and AES-NI.
• 2GB DDR3L RAM, soldered
• 8GB or 16GB EMMC, soldered
  • Allegedly has an M.2 SDIO slot. However I have not opened or tested it.
• Dual DisplayPort (4k30 or 1440p60)
• 5v3a (15W) power port (4mm x 1.7)
  • Note that some models are 12v. Watch out.
• Dell Wyse ThinOS (8GB Model) or Dell Wyse ThinLinux (16GB Model)

Linux Distros

Ubuntu

Ubuntu desktop will not install onto the thin client. The Ubiquity installer freezes on the keyboard layout screen.
Furthermore, 8GB is too small to fit the full desktop install.

Instead, you can install Ubuntu Server and then install ubuntu-desktop-minimal.

Debian

Reference

1. Install Debian as usual
2. After installation, reboot the Debian installer into rescue mode and select "Force GRUB installation to the EFI removable media path".
   • If you need to select the root partition, it should be the second option (mmcblk0p2 or mmcblk1p2).
   • Select yes if rescue mode asks to mount /boot/efi.

Reflashing ThinOS

1. Download an install the Wyse USB imaging tool
   • Note I could only get this to work properly in a virtual machine
2. Download ThinOS 9.1 Merlin
3. Flash ThinOS installer onto a USB disk
