Enable remote access Ubuntu 10.04 using command line

Posted on

To get a desktop enable for remote access you could use the command line to ensure that regarding which of you user have access on the PC you are able to help out in trivial task.

To do so you could run this line as root:

gconftool-2 –direct \
–config-source xml:readwrite:/etc/gconf/gconf.xml.mandatory \
–type bool \
–set /desktop/gnome/remote_access/enabled true

 

Sometimes the machines is unattended, so if no user is around to give you access then you will not be able to get that session. To disable the prompt message just type:

 gconftool-2 –direct \
–config-source xml:readwrite:/etc/gconf/gconf.xml.mandatory \
–type bool \
–set /desktop/gnome/remote_access/prompt_enabled false

This is up to the admin, this could just hide that you access that session, just be careful. This settings has privacy issues.

gconftool-2 –direct \
–config-source xml:readwrite:/etc/gconf/gconf.xml.mandatory \
–type string \
–set /desktop/gnome/remote_access/icon_visibility never

Comando para cambiar botones a la derecha ubuntu 10.04

Posted on

Esto es un poco engorro, para cambiar los botones de las ventanas a la derecha como en windows que funcione para todos tus usuarios ejecuta esto como root:

gconftool-2 –direct \
–config-source xml:readwrite:/etc/gconf/gconf.xml.mandatory \
–type string \
–set “/apps/metacity/general/button_layout” –type string “menu:minimize,maximize,close”

si desea puedes quitar menu y queda sin el punto a la izq. pero bueno es algo personal.
How can I move the window buttons to the top right of the window?


HOWTO Account Tracking Konica Minolta C220 under linux

Posted on

I assume that you have your Konica Minolta Bizhub working fine under linux, but as soon as you enable account track, it stop working under linux (I am on Ubuntu 10.04). Looks like there is a problem on some PJL commands that the linux driver does not forward to the printer, so a solution to this problem is to create a filter that add those. You maybe have a config with at least those elements:

<Printer KONICA-MINOLTA-C360Series>
DeviceURI ipp://192.168.252.222/ipp
Filter application/vnd.cups-raw 0 –
Filter application/vnd.cups-command 0 commandtops
Filter application/vnd.cups-postscript 0 –
</Printer>

Change that to

<Printer KONICA-MINOLTA-C360Series>
DeviceURI ipp://192.168.252.222/ipp
Filter application/vnd.cups-raw 0 minolta
Filter application/vnd.cups-command 0 commandtops
Filter application/vnd.cups-postscript 0 minolta
</Printer>

Then create /usr/lib/cups/filter/minolta so it inject some PJL commands. And give it a execute permission chmod +x minolta :

#!/bin/bash

source /etc/cups/ppd/${PRINTER}.km

echo -en “\033%-12345X”
echo -en “@PJL JOB\015\012”
echo -en “@PJL SET KMSECTIONNAME = \”${ACCOUNT_NAME}\”\015\012”
echo -en “@PJL SET KMSECTIONKEY2 = \”${ACCOUNT_PASSWORD}\”\015\012”
echo -en “@PJL SET KMCOETYPE = ${ACCOUNT_COETYPE}\015\012”
echo -en “@PJL ENTER LANGUAGE = POSTSCRIPT\015\012”

cat –

echo -en “\004\033%-12345X\015\012@PJL EOJ\015\012”
echo -en “\033%-12345X”

Then create a file /etc/cups/ppd/KONICA-MINOLTA-C360Series.km and change name and password to match your setup

ACCOUNT_NAME=”user”
ACCOUNT_PASSWORD=”1234″
ACCOUNT_COETYPE=”0″
