HOWTO: Use animated XScreenSaver matrix backgrounds with Xfce

Filed under: Blog — krkhan @ 7:13 pm

Screensavers like glmatrix have long been used by *nixers to woo people by showing them customizable animations as desktop wallpapers. Users of desktop environments such as Xfce have to however use xwininfo to determine and use the window IDs of their desktops (as the “-root” option stops working when the root window is overlayed by respective desktop managers e.g., Xfdesktop). For those who want to automate the startup process of XScreenSaver wallpapers in such environments, here’s a quick command you can use:

$ /usr/libexec/xscreensaver/glmatrix -window-id $(xwininfo -name "Desktop" | grep 'Window id' | sed 's/.*\(0x[0-9a-z]*\).*/\1/g')

Results:

  1. thanks, though I can’t see my desktop icons but for the update frame, such as clicking the desktop BG.
    (the overlay BG flashes for a second, before being overdrawn by the screensaver)

  2. I did this on xubuntu 14.04 and I had to change the code to the following to get it to work.

    /usr/lib/xscreensaver/glmatrix -window-id $(xwininfo -name “Desktop” | grep ‘Window id’ | sed ‘s/.*\(0x[0-9a-z]*\).*/\1/g’)

    my favorite is this one.

    /usr/lib/xscreensaver/blocktube -window-id $(xwininfo -name “Desktop” | grep ‘Window id’ | sed ‘s/.*\(0x[0-9a-z]*\).*/\1/g’)

    Another issue that I have is that transparency of my terminal emulators don’t work while running this.
    Anyone know if it’s possible to work around this?

  4. ah crap, I forgot to change the size of the image…
    just edit the size from s1152 to s3200 when you click the link.

    or here’s that done for you:
