Comandi vari

Riempire i frame buffer di dati casuali:

# cat /dev/urandom > /dev/fb0

Far partire X da DPI:

# FRAMEBUFFER=/dev/fb0 startx

Inviare comandi da DPI alla consolle su X:

# DISPLAY=":0" mplayer video.mp4

Non ricordo piu' a che serve :-(

# apt-get install xinput
# xinput list
# apt-get install evtest

Photo frame

# mplayer mf://*.jpg -mf fps=0.1 -loop 0

DOOM

# FRAMEBUFFER=/dev/fb0 startx &
# DISPLAY=":0" /usr/games/chocolate-doom -width 320 -height 240
