Default XFce picture viewer on Slackware Linux is GIMP (GNU Image Manipulation Program). Though GIMP is great for picture editting, it is rather strange why Patrick Volkerding compiled XFCE to use GIMP as a default picture viewer? The downsides of GIMP being default picture viewing program for Slackware's XFCE are the same like Xubuntu's XFCE risterroro, you can't switch easily pictures back and forward with some keyboard keys (left, right arrow keys, backspace or space etc.). Besides that another disadvantage of using GIMP are;
a) picture opening time in GIMP loading is significantly higher if compared to a simple picture viewer program like Gnome's default, eye of the gnome – eog.
b) GIMP is more CPU intensive and puts high load on each picture opening
A default Slackware install comes with two good picture viewing programs substitute for GIMP:
- Gwenview
-
- Geeqie
-
Both of the programs support picture changing, so if you open a picture you can switch to the other ones in the same directory as the first opened one.
I personally liked more Gwenview because it has more intutive picture switching controls. With it you can switch with keyboard keys space and backspace
To change GIMP's default PNG, JPEG opening I had with mouse right button over a pic and in properties change, Open With: program.
If you're curious about the picture on on all screenshots, this is Church – Saint George (situated in the city center of Dobrich, Bulgaria).
St. Georgi / St. George Church is built in 1842 and is the oldest Orthodox Church in Dobrich.
In the Crimean War (1853-1856) the church was burned down and was restored to its present form in 1864.
gpicview is another cool picture viewing program, I like. Unfortunately on Slackware, there is no prebuild package and the only option is either to convert it with alien from deb package or to download source and compile as usual with ./configure && make && make install .
Downloading and compiling from source went just fine on Slackware Linux 13.37gpicview has more modern looking interface, than gwenview and geeqie. and is great for people who want to be in pace with desktop fashion 🙂

My sister, experience some programs running with wine (Windows Emulator) to crash on her Ubuntu 11.10.
As she is quite new with Linux, she has no idea about the existence of CTRL ALT BACKSPACE key combination to restart a hanged GNOME, KDE by directly killing the Xorg server.
I felt obliged to explain her it is better to use CTRL ALT BACKSPACE X kill switch instead of restarting the whole Linux kernel (which basiclly is working) and that it is just the display keeping blacnk.
Pressing the would kill Xorg and therefore all applicatins previously running on top of it will die. In Ubuntu Xorg is configured to run via gdm, so once killed it will automatically reload the GDM (Gnome Display Manager).
I was about to explain her that its better she use CTRL+ALT+BACKSPACE instead of restarting the whole system but suddenly I realized this is not working.
In UBUNTU 11.10 and I guess in all UBUNTU's after 9.04 CTRL ALT BACKSPACE is substituted with the key switch combination ALT PRINTSCREEN K, I've explained her about that.
This change is actually a change implied by most Linux distributions nowdas and is some kind of change in Xorg newer versions…
To enable back the CTRL + ALT + BACKSPACE , I've issued cmd:
stanimira@ubuntu~:$ echo' setxkbmap -option terminate:ctrl_alt_bksp' >> ~/.xinitrc
An alternative way to set setxkbmap -option terminate:ctrl_alt_bksp to run on Ubuntu user login is by setting it as a startup application using;
stanimira@ubuntu:~$ gnome-session-properties
Press the Add button and type in the box to appear;
Name: setxkbmap
Command: setxkbmap -option terminate:ctrl_alt_bksp
Comment: setxkbmap
Reverting the Xserver kill switch back to the classical Ctrl+Alt+Backspace should also be running fine on older Ubuntu Linuces – 11.04, 10.10, 10.04 etc.

As I’m manually configuring a Xserver via xorg.conf I have noticed a block of code in:
Section "Monitor"
Identified "Generic Monitor"
Option "DPMS"
EndSectionThat triggered my curiousity to research further what is DPMS . A very quick google search revealed that DPMS’s purpose is to communicate to communicate between the monitor and the computer, to make the computer turn off the (CRT or LED) based monitor if the computer is not used
Thus in short to rephrase DPMS is a power saving handy Xorg feature. I many custom configured xorg.conf like the mine I’m building right now does not include DPMS as many people doesn’t have idea what DPMS is and how to enable it.
DPMS is also an interface to the Energy start power-saving capability if not all, most of the modern day monitor screens.
DPMS enables the Xserver to control automatically the computer screen and thus reduces the overall computer power consumption.
To enable the use of DPMS on my Linux, all I had to do is place a couple of configuration directives in my xorg.conf .:
Here is how I enabled DPMS in my Xorg server:
1. Edit with a text editor /etc/X11/xorg.conf
2. Find the Monitor Section , e.g.:
Section "Monitor"
....
EndSection
3. Add inside the Monitor Section Options "DPMS" "true"
4. Lookup for the ServeryLayout section , e.g.:
Section "ServerLayout"
...
EndSection
5. Place inside the ServerLayout section For instance the following options:
Option "StandbyTime" "20"
Option "SuspendTime" "10"
Option "OffTime "25"
You might like to change the options StandbyTime, SuspendTIme or OffTime to match your likings.
6. As a last step restart the Xorg server.
Press Ctrl+Alt+BackSpace or by issuing:
host:~# pkill -HUP X
Test that DPMS is loaded properly by reviewing /var/log/Xorg.0.log for example:
host:~# grep -i /var/log/Xorg.0.log
(II) Loading extensions DPMS

I’ve recently realized that the CTRL + ALT + BACKSPACE keyboard combination is no longer working in Debian unstable.
This good old well known keyboard combination to restart X is not working with my xorg 7.5+8 under my Gnome 2.30 desktop
However thanksfully there is another combination to kill the X server if for instance if your Gnome desktop hangs.
If that happens simply press ALT + PRINTSCREEN + K this will kill your X and then reload the (Gnome Display manager) gdm.
Another suggestion I’ve red in the forums of a way to enable back CTRL+ALT+BACKSPACE is to put in either .bashrc or .xinitrc the following command
setxkbmap -option terminate:ctrl_alt_bksp
BTW It’s better that the above command is placed in ~/.xinitrc.
I’ve also red on some forums that in newer releases of Ubuntu. The CTRL+ALT+BACKSPACE can be enabled using a specific command, e.g. with:
dontzap -disable
