xpra + CubieTruck >

---

Tested 2014-01-09 with

• host: xpra v0.3.11 on Lubuntu 1.00 on the cubietruck aka "Linaro"

• client: xpra v0.10.6 on Lubuntu 13.10, updated recently.

Result: Unusably slow.

On the desktop ∞

  \sudo  \apt-get  install  xpra

On the cubietruck ∞

I tried installing from packages:

  \sudo  \apt-get  install  xpra

This gave me v0.3.11, which was unbearably slow.

On the cubietruck ∞

  \xpra  start  :100

Start your application like so:

  DISPLAY=:100  \lxterminal &

Replace lxterminal with whatever you like.

You can either kill the xpra task or stop it with:

  \xpra  stop  :100

Learn the cubietruck internal IP address ∞

Learn a Linux computer's IP address

Connecting with the client computer ∞

  \xpra  attach  ssh:username@host:100

This is very slow. Unusable! I suspect it's because it's ancient.

An attempt to install a newer xpra on the cubietruck ∞

I tried installing from source:

  version=xpra-0.10.11
  # e.g.  xpra.org/src/xpra-0.9.7.tar.xz
  \wget  -c  xpra.org/src/${version}.tar.xz
  \tar  xf  ${version}.tar.xz
  \cd  $version
  
  # "reset" from any previous compile attempt
  \rm  --force  --recursive  build  install
  \sudo  \apt-get  install  build-essential
  # compile.
  \sudo  CFLAGS=-O0  \python  setup.py

gives me:

  setup.py

.. I have no clue how to troubleshoot.
