[Libdlo] Frame Buffer with UDLFB broken since disabling defio

[Justin Hammond]

Hi,
I'm using a Mimi 720 and saw that there was a recent commit to enable DPMS.
I've upgraded, but all of a sudden my QT Embeded application has stopped
working. I've also check with other apps, such as mplayer and that is also
not working.

I've narrowed it down to this commit:
http://git.plugable.com/gitphp/index.php?p=udlfb&a=commit&h=dba564a4a31bdf62a0e9768cbcdcce4edf85618a

Previous versions worked fined with both my app and mplayer. On module load,
I get the green screen.... :)

Not sure what the defio code has disabled... but would be nice to get it
working again...

(btw, as far as I can tell, the DPMS code works fine. "echo 1 >
/sys/class/graphics/blank" turns off the monitor... 0 turns it back to
greenscreen!)

(mplayer command line: mplayer -vo fbdev2:/dev/fb1 /home/movies/IceAge-2.avi
)
