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 backspaceTo 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 🙂
How to enable Ctrl+Alt+Backspace in Ubuntu 11.10 (Oneiric Ocelot) Linux
Monday, January 16th, 2012My 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.
