Useful boot process commands in Debian Squeeze


  • Pause or resume the boot process. Useful if something catches you eye.


  • Skip the current boot process step



Network-Manager applet missing if / eth0

It seems that network manager is not configured to manage interfaces which ifup/ifdown is configured to maintain

gksu gedit /etc/NetworkManager/nm-system-settings.conf


gksu gedit /etc/NetworkManager/NetworkManager.conf (appears to have changed to this since squeeze has gone live)



# restart networking
/etc/init.d/network-manager restart

A flicker free conky

My conky was a little wonky. I had flickering and a constant resizing issue. I had not had this for several years; conky just seemed to work for me. I have two laptops running Debian Squeeze one is perfect the other brought back haunting memories of trying to fix this last time.

  • Install wmctrl; “apt-get install wmctrl


  1. Turn on dbe x module; this seemed to actually be on by default.
  2. If you don’t have xorg.conf see my previous post
  3. Inside /etc/X11/xorg.cong load the dbe module
  4. Look for a section called ‘Section “Module”‘ and underneath add ‘Load “dbe”

Section “Module”
Load  “glx”
Load  “dbe”


Add the following into ~/conkyrc

  • Place before “TEXT
  • Note you will need to change the dimensions of the max and min size to be your required size; the only important requirement here is that they should both be equal

double_buffer yes
own_window no

minimum_size 300 1000 # WIDTH HEIGHT
maximum_size 300 1000 # min and max should be equal

  • Place as the very last line

${execi 6000000 wmctrl -a conky}

Upgrade Debian Lenny to Squeeze

To update from debian lenny to squeeze (currently testing) you simply need to change your sources list to read squeeze for the distribution version.

cp /etc/apt/sources.list /etc/apt/sources.list.old

gedit /etc/apt/sources.list

Replace stable/lenny with squeeze. Best to have squeeze as aposed to testing so you don’t upgrade to the new testing when squeeze is made stable.  Then perform the following commands.
aptitude update

aptitude install apt dpkg aptitude

aptitude full-upgrade

aptitude clean

aptitude autoclean
