Dockstar with minimal Desktop VNC

Hi,

i found a lot if howtos with installing vnc and desktop on dockstar.
But no one shows a solution, how you get a remote desktop from start.
every time you have to put several commands to start vnc and remote desktop.
Can we make it easyer for all?
How could we offer a vncserver on boot with desktop like icewm oder wdm?

Big thanks for help

Greetings
Bye

use freenx this uses the rdp proto and is mouch faster and uses only the ssh port
here is a sample install WIKI

sorry german only

Hi,
thanks for replay!I installed it.But Vnc is much easyer, i guess.
Iam a german one :-)
No problem for.

Can´t we get a easy script for starting such a xvfb and x11 session?
No idea?
Thanks

I tried VNC but it was too slow to be useful. I have not tried freenx yet.

Hi,
FreeNX works, but have a very bad display settings.
I can´t chance the settings from 1680x1016 to 800x600!
Can anyone help how to do?
In client settings are 800x600, but the session starts with the max size.
How could i cange it on server side?

I uses LXDE with nxserver.

Thanks for help!!

Can you write some simple steps on how to get FreeNX work?

I'll have a bash at a quick and dirty vncserver + fluxbox set up...

To install:

apt-get install fluxbox tightvncserver xfonts-base rxvt iceweasel
vncserver :1 # first run to create ~/.vnc directory. Create password if prompted
vncserver -kill :1 # shut it down
# install fluxbox as window manager for vncserver
perl -pi -e 's/xrdb.*$/"$&\nfbsetroot -solid black\nfluxbox &\n"/e' ~/.vnc/xstartup

To start...

vncserver -geometry 800x600 -depth 16 :1

To stop...

vncserver -kill :1

Hi,

I advice to use tight compression - it is speeding up interaction with dockstar.

Regards,
Adam.

I this faster als NX Server??
NX Server is realy fast, but even difficult to administrate and to log in with client.
With vnc you only need on file (vnc client) to access the docstar.

Can you say somethink about performance?
How can i activate tight compression?

How can i do this with lxde?
I guess ist much faster as fluxbox.

THANKS!!

lxde is slower than fluxbox.

To use...

apt-get install lxde

vi ~/.vnc/xstartup

#add the following in place of fluxbox...
lxsession -s LXDE &

Then start the same way as before...

vncserver -geometry 800x600 -depth 16 :1

To activate tight compression connect using a VNC viewer that supports tight compression (i.e. windows client from tightvnc.com or apt-get install xtightvncviewer)

-PG

FYI - lowering vnc display depth makes a huge difference in memory usage.

Without vncserver I have 9Mb used and 112Mb free:

root@debian:~# free -m
             total       used       free     shared    buffers     cached

Swap:          544          0        544

Starting vncserver uses only 4Mb of RAM:

Still got 35Mb free :-)

I've done what you said here. How do I connect to it using tight vnc? I typed in the IP of my dockstar, not sure what port it would be using?

Yes! Thanks to all for posting in this thread - it works well enough for me to post this to you straight from my AccessPoint|NAS|PrintServer that is running Debian (w/ hostapd, Netatalk&Samba, p910nd), with minimal lag while I type. True, more involved graphics are slower (as one would expect) but it is usable for what we would needed it for.

Hi,
i have some problems to make snapshots to my Picture Frame.
In my VM Ware environment works all fine, but i have no glue to make snapshots from my xvfb.
What i want: start freevo in xvfb and use a samsung DPF as mini Monitor with lirc

Here´s my working script in a VM(not working with Dockstar and xvfb)

#!/bin/bash
# Take screenshot of Screen 15 seconds after the script is executed
# Handy if you want to take screenshots of Games in Fullscreen in GNU / Linux and FreeBSD
# The script requires import (part of ImageMagick)
screenshot_dir="Screenshots";
# 300 secs (5 mins)
seconds='1';
if [ ! -d "$screenshot_dir" ]; then
mkdir $screenshot_dir;
fi
while [ 1 ]; do
sleep $seconds;
#(scrot $screenshot_dir/'$wx$h_bild.jpg') &
#(scrot -t 60 $screenshot_dir/'%Y-%m-%d_$wx$h.jpg') &
(nice -n 19 scrot $screenshot_dir/'$wx$h_bild.jpg') &
nice -n 19 python pyframe_basic /home/Pyframe/Screenshots/800x600_bild.jpg 1>/dev/null 2>/dev/null
done

Script with fluxbox and conky, can´t implement firefox/freevo to test (Dockstar fluxbox and conky only ;-( )

#!/bin/sh
# Take screenshot of Screen 15 seconds after the script is executed
# Handy if you want to take screenshots of Games in Fullscreen in GNU / Linux and FreeBSD
# The script requires import (part of ImageMagick)
killall conky 2>&1 >/dev/null
killall Xvfb 2>&1 >/dev/null
rm /tmp/.X13-lock 2>&1 >/dev/null
Xvfb :13 -screen 0 800x600x16 &
export DISPLAY=:13.0
screenshot_dir="Screenshots";
# 300 secs (5 mins)
seconds='10';
if [ ! -d "$screenshot_dir" ]; then
mkdir $screenshot_dir;
fi
conky -p 0 -c /home/test/.conkyrc &
fluxbox &
#iceweasel     <- no iceweasel at JPG
#freevo   <- also freevo !
while [ 1 ]; do
sleep $seconds;
#(scrot $screenshot_dir/'$wx$h_bild.jpg') &
#(scrot -t 60 $screenshot_dir/'%Y-%m-%d_$wx$h.jpg') &
(nice -n 19 scrot $screenshot_dir/'$wx$h_bild.jpg') &
nice -n 19 python pyframe_basic /home/Pyframe/Screenshots/800x600_bild.jpg 1>/dev/null 2>/dev/null
done

Fluxbox with conky starts, but no freevo or iceweasel (have to removed the hashes #)
How can i autostart xvfb Headless with freevo and my Picture Frame get some pictures every x seconds with pyframe ?

I hope someone can me help with the script ...

many thx
rebdel

I've been just using stuff like:

ssh -c blowfish -X user@192.168.2.4 firefox
ssh -c blowfish -X user@192.168.2.4 gnome-terminal

Isn't using VNC or other similiar service less accurate and more overhead? Cygwin/X is a reasonable free X server for windows if that's the hangup. Seems like all I give up is a desktop.

I like to use my Dockstar as a MP3 Mediaplayer with GUI and Lirc ...

Okay the first script works when i´m remoteley connected with xrdp ..
My Problem is i have only 1920x1080 snapshot´s, i dont want to resize with scrot...

How can i change the resolution to 800x600x16
vncserver -geometry 800x600 -depth 16 :1

when i start mstsc -> Sesman-xvnc with my account i have Full HD ...

~/.vnc/xstartup

#!/bin/sh
xrdb $HOME/.Xresources
fbsetroot -solid black
fluxbox &

Any Ideas to change resoltion fix to 800x600 ??

THX

If you only want to run a few GUI-apps (e.g. because they don't support CLI) then you might find xpra very useful!
You can describe it as "screen for X" (screen=a program to let programs run while you're disconnected from your box).
Start a GUI-program on your box, control it on your host machine, then detach and let it run while disconnected. You can then reconnect to the same instance later.

thx fluffy, i give it a try ...

My Problem was fixed, i use now MMS with these Python Scripts:
