[too slow] From packages ∞
Installing ∞
\sudo \apt-get install xpra
On the Raspberry Pi ∞
Start it up with:
\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 Raspberry Pi internal IP address ∞
Learn the internal IP address of your Pi. You can either run ifconfig to get it, or script it:
\ifconfig wlan0 | \grep inet\ addr: | \cut -d':' -f2 | \cut -d' ' -f1
Change wlan0 to eth0 if you're using a wired connection.
On the client computer ∞
\xpra attach ssh:username@host:100
This is very slow. Unusable! I suspect it's because it's ancient.
[fails] From source ∞
Compiling/Installing ∞
local version=xpra-0.9.7 # 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 # I think this is to "reset" from any previous compile attempt \rm -rf build install # compile. The two --without-foo are to avoid errors. This may be the cause of my woes. \sudo CFLAGS=-O0 \python setup.py --without-x264 --without-vpx install
Running ∞
Compiling from source, I can't get it to work at all.
I can make xpra launch, but it doesn't do anything.
\xpra start :100 --no-daemon

I get a nonsense error when trying to attach:
\xpra attach ssh:pi@192.168.0.3:100
xpra client version 0.9.7 2013-07-27 11:12:40,139 Connection lost 2013-07-27 11:12:40,140 connection closed after 0 packets received (0 bytes) and 1 packets sent (7350 bytes)
.. this is when I got the idea to start xpra with --no-daemon to get some output.
At first the log file was never particularly helpful, but after waiting for a while and checking it, it does give the final traceback. I guess I was impatient before.

Works fine for me from the stock Raspbian repositories. It's never going to be very fast due to the limitations of the Raspberry Pi, but is usable.
