Launch a text program inside a konsole at startup
Hi ULFers,

I am trying to setup a (very) simple startup script on a centos 6.4 computer and it kind of failed.... Here are the details :

As said just above the computer setup is running a CentOS 6.4 x64, on this computer a vncserver is automatically started (by a chkconfig vncserver on), i use this vncserver to remotely access the computer and to run ktorrent too.
This setup worked very well for the last 3 years (upon different Fedora based distros).

I have to use rtorrent for some private tracker, i then would like to make it (rtorrent) startup automaticallyjust like ktorrent.

I wrote a little piece of script to achieve what i thought to be a simple and quick task, BUT, it doesn't work.

I created a new user (called rtorrent_user) to run rtorrent app, i also setup a sudo to allow the vncserver user to run rtorrent app as rtorrent_user.

When i launch the script from a konsole everything works, but when i setup the script for an automatic startup (symlinking manually or using the CentOS GUI) the script ran but no konsole+rtorrent appears...

If you have an idea ???


Here is the script :
Code:
#!/bin/bash

# Start rtorrent automatically when vncserver start for user "pier"
# add rtorrent to the X server "access control list" :
wall "launched"
xhost + SI:localuser:rtorrent
# Now start rtorrent from inside a "konsole" (the following requires a correct sudoers file) :
konsole -e sudo -u rtorrent konsole -e rtorrent

The wall command allow me to ensure the script was really launched at startp, and it did but nothing happened after....

vncserver

vncserver(1)							     TightVNC							      vncserver(1)

NAME

       vncserver - a wrapper to launch an X server for VNC.

SYNOPSIS

       vncserver [:display] [-geometry widthxheight] [-depth depth] [-pixelformat rgbNNN|bgrNNN] [-name desktop-name] [Xvnc-options...]

       vncserver -kill :display

       vncserver -help

DESCRIPTION

       vncserver is a wrapper script for Xvnc, the free X server for VNC (Virtual Network Computing). It provides all capabilities of a standard X
       server, but does not connect to a display for itself.  Instead, Xvnc creates a virtual desktop you can view or control remotely using a VNC
       viewer.

OPTIONS

       You  can  add  Xvnc  options at the command line. They will be added to the invocation of Xvnc without changes. The options provided by the
       vncserver itself are as follows:

       :display
	      The display number to use. If omitted, the next free display number is used.

       -geometry widthxheight
	      Set desktop width and height.

       -depth depth
	      Set the colour depth of the visual to provide, in bits per pixel. Must be a value between 8 and 32.

       -pixelformat rgbNNN|bgrNNN
	      Set colour format for pixels representation. The viewer can do the conversion to any other pixel format, but it  is  faster  if  the
	      depth and pixel format of the server is the same as the equivalent values on the viewer display.

       -name string
	      This specifies the name of the desktop.

       -kill :display
	      Stops the session running on the specified display.

       -help  Prints a short usage notice to stderr.

EXAMPLES

       vncserver
	      Invokes Xvnc on the next available display and with suitable defaults.

       vncserver :1
	      Invokes Xvnc on display :1.

       vncserver -geometry 800x600 -depth 16 :1
	      Invokes Xvnc on display :1 with desktop size of 800x600 pixels and color depth of 16 bits per pixel.

       vncserver -kill :1
	      Shuts down Xvnc server on display :1.
