 Posted: Thu Sep 23, 2004 8:12 am Post subject: HOWTO get a matrix-like "animated" Background |
 |
|
Hi,
i´ve stumbled upon this while reading the manpages of Eterm, which provides a flag:
| Code: |
-q, --no-input Keeps Eterm from accepting keyboard input, and keeps the windowmanager from focusing it.
Useful for LOG-TAILERS and such. |
As it´s very easy, just try it out:
| Code: | | Eterm -O -g 140x40 --bold-font 10x20 -f Green -L 2000 -l --double-buffer --scrollbar-width 0 --buttonbar false -w=0 -c Green -x -q -e cat /dev/random |
As you will see, this command creates a transparent, borderless Eterm with a scrolling random-Output, which doesn´t get focused by the mouse and doesn´t accept input 
Maybe you got to modify this line to meet your desktop-settings (font, geometry etc.)
TIP:
-with the use of transset. you can achieve really nice effects
-if you don´t like /dev/random, you could tail some log to the Eterm, which also gives a nice background.
That´s all, and it´s my first mini-Howto, so don´t kill me if it doesn´t work - but tell me if you have some improvements. |

Very nice tip. I've used this type of thing for log files, it's a nice thing.

If you can't get that to work, try using | Code: | | usr/lib/xscreensaver/xmatrix -root & |
It's essentially the non-opengl version of the same thing. I have to admit.. I didn't realise it was possible to have an opengl desktop before... |

|

Hi,
It isn't as cool as xmatrix, or glmatrix... but I think that using it with cmatrix would be nice. You have to emerge cmatrix, then run: | Code: | Eterm -O -g 140x40 --bold-font 10x20 -f Green -L 2000 -l --double-buffer --scrollbar-width 0 --buttonbar false -w=0 -c Green -x -q -e cmatrix -bax
|
I like it... Also, the glmatrix -root, or xmatrix -root might not work, if you use something else for your desktop... like nautilus, xfdesktop |

Is there a way not to use nautilus as my desktop? I'm running gnome, I still would like the gnome toolbars to be there, but I don't really care about the desktop. Is there a way to make glmatrix my desktop in this case? I looked around in the gdm, X11, etc. scripts and conf files, but nothing popped out... thanks! |

Well, answered my own question, found the info here:
http://gnome-hacks.jodrell.net/hacks.html?id=44
1. Disable Nautilus from drawing the desktop
(open gconf-editor and browse to apps->nautilus->preferences , then uncheck the
"show_desktop" option
2. Select and configure the screensaver you want
(Open the screensaver prefs as if you were configuring your screensaver,
configure the one you want and then click settings -> advanced. Copy the
command line specified there)
3. Set this to run on login
(Open the sessions preferences, select the startup programs tab and add in the
command that you copied in step 1.)
Log out and back in again and lo and behold, you have a screensaver running as
your background. (You don't really have to log back in, just run whatever your screensaver command was in the background. |
