UPDATE: This has been verified to work for 7.10 (Gutsy) as well as 7.04 (Feisty).
For whatever reason in Ubuntu the GLSlideshow screensaver settings are not accessible through the screensaver control panel. We're talking the basics here, like changing the filesystem path to the pictures to display, displaying more than one image (in true slideshow fashion), the duration to display a picture for, etc. So then how does one adjust these properties? This post answers that question.
GLSlideshow gets its settings from two files. The first is .xscreensaver, and the second is glslideshow.desktop. We'll tackle these one at a time.
Starting with .xscreensaver, this file should exist in your home directory; if it doesn't already exist go ahead and create it there. Add the following line to .xscreensaver, where the path represents the folder containing the images you wish to display (adjust the path appropriately for your environment):
imageDirectory: /home/username/Photos
Save this file and close it.
Next modify the settings in glslideshow.desktop to get GLSlideshow to perform as we would like. In Ubuntu this file is typically found here:
/usr/share/applications/screensavers/glslideshow.desktop
If this path isn't appropriate for your system, issue this command to locate this file:
slocate glslideshow.desktop
Edit gslideshow.desktop and look for the following entry:
Exec=glslideshow -root
Modify this line to instead read:
Exec=glslideshow -root -duration 15 -pan 15 -fade 5
Where:
- duration represents the amount of time (in seconds) to display an image for
- pan represents the amount of time (in seconds) to run the pan effect on this image
- fade represents the transition time (in seconds) to fade between images
Save this file, then activate the screensaver. GLSlideshow should now present a slideshow of images from the specified directory.

Hey, I just wanted to thank you for making this available.
FYI: All of the above instructions still hold true for Ubuntu 7.10 (Gutsy Gibbons).
thanks a lot, just what I was looking for
Thank you, this information is spot on. :)
thx very much...works perfect
Awesome mate, thanks heaps. Lovin Ubuntu, this distro rocks!
ty, very helpful
Works in Hardy (8.04) alpha 4 too.
Adding the following line to the .xscreensaver file will also make this random:
chooseRandomImages: True
Thanks a lot for this explanation. I just want to add the following: On/off-options have to be unset (i.e. deleted) in .xscreensaver, such as "-clip" (of course, delete it when only you don't want it).
works under hardy 8.04.1, thanks for the guide!
still works 8.10 the folks at gnome are so silly for not providing a gui for this
Thanks very much. I don't understand why Gnome doesn't make something as routine as this more user-friendly. This seems to be a good example of what users used to KDE, osx (or even windoze) get frustrated by when trying to switch to gnome.
Great! Still working in Ubuntu. Thank you for sharing.
For some reason when I change the options in the glslideshow.desktop file, the changes don't take effect. I've switched screensavers, even restarted. I'm using 8.10. Anyone have any thoughts?
Thanks for the tip.
FYI, 'man glslideshow' will give you all the available options.
For me, I have also specified the '-clip' option which stops black bars appearing at the sides of an image when zoomed out.
A year later, in Karmic, this information is still valuable!
Why doesn't Gnome make this part of a default GUI? Or at LEAST make everything point to a well-known place...
Still good for Ubuntu 9.10. Thanks!
Doesn't seem to work on 10.04 - I've modified .xscreensaver to contain only "imageDirectory: /home/jdoe/photos/POD/screensaver" (podget is great), but it still uses the value of XDG_PICTURES_DIR as specified in ~/.config/user-dirs.dirs. Do I need to have xscreensaver installed as well?
Works perfectly in 10.04!
Also work perfect in 10.10! Thanks
This also works with Linux Mint RC10 Julia.
Many thanks, I always wondered how to do that!
Works fine in Ubuntu 10.10. Although you might need to "killall -HUP gnome-screensaver" after modifying /usr/share/applications/screensavers/glslideshow.desktop.
Tip: Setting the delay value to something lower than the default 20000 gave me a frame rate boost. (I set it to 2000). But it also boosted my load from 60% to ~97%.. And the transitions are still in the 20 fps region :/
Very useful. Just like to add that if you see a screen meaning "Technical Problems" like those used in TV, maybe you will need to remove .xscreensaver-getimage.cache (also located in your home folder).
I found that in 11.10 (oneiric) the glslideshow flags are all set by the xscreensaver set-up dialog - there is a "Settings" button.
Editting the file given is no good - you find the file but it's ignored!
Just select GLSlideshow in the choice list and then click "Settings" in the bottom right hand side. You can then use sliders and allsorts, or click "Advanced" and then you can edit the glslideshow command.
I notice the whole command line is now saved into .xscreensaver - you could edit it there, but I'm sure using the dialog is better.
Bad News: Doesn't work with Linux Mint 17.3
Good News: Found a different work-around :)
https://github.com/linuxmint/cinnamon-screensaver/issues/105
Edit the /usr/share/cinnamon-screensaver/screensavers/xscreensaver@cinnamon.org/main file, and make the file look like this (add lines 44 to 50)
39 for direc in directories:
40 try:
41 path = shlex.split(direc + hack)
42 path.append("-window-id")
43 path.append(xid)
44 path.append("-duration")
45 path.append("20")
46 path.append("-pan")
47 path.append("20")
48 path.append("-fade")
49 path.append("3")
50 path.append("-titles")
The change doesn't work in Linux Mint 18.0 either.
Workaround:
1. Set screen-saver settings via standard Mint configuration
2. Install dconf-editor (sudo apt install dconf-editor)
3. Search for glslideshow in dconf-editor (Ctrl-F)
4. add options as wanted behind glslideshow e.g.:
glslideshow -zoom 100 -fade 2 -duration 30 -delay 20000 -titles
(I added some default figures, because some defaults were changed by Mint and I can't check them...)
5. NEVER come back in screen-saver config, or you have to retype the extra glideshow settings again.
Anyone a better workaround?
