+ | ====== On Screen Display with XOSD ====== | ||
+ | You can use XOSD to create on screen display text. The text appears at a specific location for a specific amount of time. It has several useful applications, such as displaying a notice about new messages on the screen. | ||
+ | |||
+ | I'm using it to display uptime at the top of my screen every 15 minutes. Here's what that looks like. | ||
+ | |||
+ | {{ :linux:uptime_osd.gif|{{:linux:uptime_osd.gif| }} | ||
+ | |||
+ | .\\ | ||
+ | Here's the command that displays that information for 15 seconds. | ||
+ | |||
+ | uptime | osd_cat -A center -p top -o 5 -c black -d 15 | ||
+ | |||
+ | I wrote a quick PHP script to re-run that command repeatedly. This script is then loaded in my Gnome Sessions and runs all day. | ||
+ | |||
+ | <code> | ||
+ | #!/usr/bin/php | ||
+ | <?php | ||
+ | |||
+ | // Loop forever | ||
+ | while (1 == 1) { | ||
+ | exec('uptime | osd_cat -A center -p top -o 5 -c black -d 15'); | ||
+ | } | ||
+ | |||
+ | ?> | ||
+ | </code> | ||
+ | |||
+ | And, here's another quick PHP script that plays a series of sounds while it flashes text on the screen. This is what I use to notify me when I get new IM's. Has a visual and audio hint which is useful when I have headphones connected but not in my ears. | ||
+ | |||
+ | <code> | ||
+ | #!/usr/bin/php | ||
+ | <?php | ||
+ | |||
+ | // Execute a beep, pass output to /dev/null, and background it | ||
+ | exec('beep -f 2000 -l 250 -d 250 -n -f 1000 -l 250 -d 250 -n -f 2000 -l 250 -n -f 1500 -l 100 -d 250 -r 3 > /dev/null &'); | ||
+ | // Loop three times | ||
+ | for ($i==1; $i<3; $i++) { | ||
+ | // Display a message on the screen | ||
+ | exec('echo \'New Instant Message \' | osd_cat -A right -p bottom -o -100 -c red -s 2 -d 1 -f -adobe-helvetica-bold-*-*-*-34-*-*-*-*-*-*-*'); | ||
+ | // Pause one second | ||
+ | sleep(1); | ||
+ | } | ||
+ | |||
+ | ?> | ||
+ | </code> |
