I am running the 13.04.24 version of ltib (Linux version 3.0.35-2508-g54750ff), and video usually starts up during boot (I get 4 penguins while the kernel is booting, and the matchbox desktop comes up).
Every now and then, I get no display on the LCD but the system seems to run fine otherwise. Unblanking the display with:
echo 0 >/sys/class/graphics/fb0/blank
cat /etc/splash.bmp >/dev/fb0
echo -e -n "\33[9;0]\33[14;0]" >/dev/console
does not do anything, so I don't believe it to be in the screen blanking subsystem.
Does anyone have suggestions on how to debug this problem? It is an intermittent problem that happens with either resets or power cycling. There are no differences in the dmesg output between a successful reboot with graphics and one without.
.
Thanks,
Wayne
