XFCE does not come with a system monitor utility like the one I had in Gnome. I used the utility to kill unresponsive processes. So how do we kill unresponsive programs using the terminal? To understand how Linux handles processes and how you can control them read this great article by Gary Sim (in plain English). Here is what I learnt from Gary’s article.

We need to know the process id of the program that is not responding. We find out process id or PID by running the command

ps aux

This command displays all running processes. Below are a few of the many running processes on my computer. The list is long so I am only showing you a few to give you an idea.

USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
nom 3006 0.0 0.3 2476 772 ? S 23:15 0:00 gnome-pty-helpe
nom 3097 0.0 4.0 16584 10348 ? Ss 23:23 0:01 gksu -u root /u
root 3102 0.0 0.4 3712 1068 pts/1 Ss+ 23:23 0:00 /bin/su root -c
root 3105 0.0 0.2 2256 592 pts/1 S+ 23:23 0:00 /usr/lib/libgks
nom 3321 0.7 3.2 14920 8364 ? Ss 23:44 0:01 mousepad


Now find out which one of them you want to kill. I want to kill the mousepad it has the PID 3321 and I kill it by running this command:

kill 3321

Just incase if this command doesn’t work you can try

kill -9 3321


I am very happy with XFCE. But I need to find out a nice and lite pdf viewer. Evince is great but how could I download evince without downloading so many gnome libs? There is an evince-gtk package in Debian experimental but I can not install it due to dependency issues.

I am using Linux for more than a year now so I am comfortable with commands. Since I was going to install new things so it was wise to log in with super user priviledges.

nom@debian:~$ su
Password:
debian:/home/nom#


Once logged in, I had to tell apt to use network proxy. I did that by running the command:


export http_proxy=http://[proxy.address]:[port]


This command is temporary solution and you will have to repeat it with each new session. There is a workaround to set this up permenantly.

I installed XFCE4 by running the command:

apt-get install xfce4

I was foolish, I thought I would be able to log in a nice GUI world by simply downloading XFCE4. I forgot that I should also download gdm and xorg.

apt-get install gdm, xorg

Even then I was unable to log in to the gdm. So I ran:

dpkg-reconfigure xserver-xorg


This command runs a nice little wizard which helps you solve issues with your xserver settings. It could be difficult sometimes if you don’t know what hardware you are using and what it is called. Like once I had this trouble and I had no other computer to connect to the internet and ask for help on the internet. At that time I learnt about lynx a text mode web browser and bitchx the IRC chat client.

After configuring xserver I logged in with GDM and entered into the brand new world of XFCE. May be its just me but XFCE in Debian is faster and prettier than Xubuntu. I still had to install iceweasel web browser, xchat, ttf-nafees font and gimp. Working in this new environment, limited set of tools and applications, I learnt that I need to download more packages. Like for example I didn’t install alsa-base package. I also didn’t have xfce4-mixer package which is required to add a volume indicator icon on panel. I also learnt that I can’t live without Synaptic package manager.

I am much happier now and satisfied for a few months at least. Basic applications are still the same. I was already using Mousepad, Iceweasel, Gimp and Xchat with Gnome. But the most notable difference is in performance. My computer is much faster now, start up time is improved and it feels so neat.

Create a file in /usr/bin/

gksudo "mousepad /usr/bin/fixkeyboard"

Add following lines in this file. I am using US and PK layouts in this example, please change it to the keyboard layouts you want to use. Also note that this example sets xkb option to change groups when both alt keys are pressed together.

#!/bin/bash
setxkbmap -option grp:switch,grp:alts_toggle us,pk

Save the file and exit.

Go to Applications > Settings > Autostarted Applications and click the Add button. In the Name feild type fixkeyboard and in the Command feild type /usr/bin/fixkeyboard press OK and then Close.

You are done. Now whenever you log on to your XFCE session you will be able to switch keyboard layouts by pressing both Alt keys together. If you don’t like the both Alt keys combination then you can try other group switch combinations. Replace alts_toggle in fixkeyboard file with one of the following options:

alt_shift_toggle
ctrl_shift_toggle
ctrls_toggle

Country flags for XFCE xkb plugin are located in /usr/share/xfce4/xkb/flags/. If your country’s flag is missing you can add it there, the file should be in png format and 60 x 40 pixels.
