How to:

  • CHANGE TIMEOUT & TRANSITION (BLEND) TIME (it’s not possible to change the transition effect)

You can override the default settings by modifying /etc/rs.conf via SSH as root (use mc -e /etc/rs.conf):

TRANSITION_TIME_S=10 # Images transition time.

BLEND_TIME_MS=600 # Images blend timing.

IMAGE_PLAYER=”fbi -autozoom -norandom -timeout $TRANSITION_TIME_S -noverbose -blend $BLEND_TIME_MS -vt 1 -readahead -cachemem 20 -once -list”

IMAGE_PLAYER_IMAGES_ONLY=”fbi -autozoom -norandom -timeout $TRANSITION_TIME_S -noverbose -blend $BLEND_TIME_MS -vt 1 -readahead -cachemem 100 -list”


VIDEO_PLAYER=”omxplayer -t off -b”


For example you can set the image slider to randomize images playback (-random flag) or enable the EXIF rotation; if you need a quicker setup (both when booting and when refreshing server content) keep EXIF rotation disabled. If you slide camera photos, keep it enabled.

When modifying images’ settings, change both the IMAGE_PLAYER* lines.

fbi is the program chosen for sliding the images and omxplayer is the one for videos’ playback (which is GPU-acceretated).
Both use the Linux framebuffer device for the output: it means there is no X.Org installed into the system.

Have a look at fbi and omxplayer man pages for help.



This program displays images using the Linux framebuffer device.
Supported formats: PhotoCD, jpeg, ppm, gif, tiff, xwd, bmp, png,
webp. It tries to use ImageMagick’s convert for unknown file formats.usage: fbi [ options ] file1 file2 … fileN

-h -help print this help text
-V -version print fbi version number
-store write cmd line args to config file
-l -list read image filelist from file
-P -text switch into text reading mode
-a -autozoom automagically pick useful zoom factor
-(no)autoup like the above, but upscale only
-(no)autodown like the above, but downscale only
-(no)fitwidth use width only for autoscaling
-v -(no)verbose show filenames all the time
-u -(no)random show files in a random order
-1 -(no)once don’t loop (for use with -t)
-(no)comments display image comments
-e -(no)edit enable editing commands (see man page)
-(no)backup create backup files when editing
-(no)preserve preserve timestamps when editing
-(no)readahead read ahead images into cache
-cachemem image cache size in megabytes
-blend image blend time in miliseconds
-T -vt start on virtual console
-s -scroll scroll image by pixels
-t -timeout load next image after sec without user input
-r -resolution pick PhotoCD resolution (1..5)
-g -gamma set display gamma (doesn’t work on all hardware)
-f -font use font (anything fontconfig accepts)
-d -device use framebuffer device
-m -mode use video mode (from /etc/fb.modes)

Large images can be scrolled using the cursor keys. Zoom in/out
works with ‘+’ and ‘-‘. Use ESC or ‘q’ to quit. Space and PgDn
show the next, PgUp shows the previous image. Jumping to a image
works with g. Return acts like Space but additionally prints
prints the filename of the currently displayed image to stdout.

The Linux framebuffer (fbdev) is a graphic hardware-independent abstraction layer to show graphics on a computer monitor, typically on the system console.

It allows direct access to the framebuffer (the part of a computer’s video memory containing a current video frame) using only the Linux kernel’s own basic facilities and its device file system interface. It does not rely on user space software like SVGALib.
