Hi, Mike Yuan,
If you want to test the graphic layer support the resolution.
You could run this in the terminal:
#dfblayer -l 0 -m 1920x1080
-l means wich layer you want to test, sometimes you could see multiple layers
by "dfbinfo"
-m meas the you resolution you want to set
Usually, if it set the resolution successfully, it will display the details.
by contraries, it will tell you "not surport".
Best regards,
chiachen

DirectFB/DirectFBCreate: Setting desktop resolution to 1920x1080
failed!=======
Hello All,
I use DirectFB on Linux2.6 and want to set graphics layer resolution to
1920x1080(mode is 1920x1080-50i), but when DirectFB
module init, we met 3 errors:
( 1 ) DirectFB/DirectFBCreate: Setting desktop resolution to 1920x1080
failed!
-> Using default resolution..
( 2 ) DirectFB/DirectFBCreate: Setting desktop format failed!
-> Using default format.
( 3 ) DirectFB/DirectFBCreate: Setting desktop buffer mode failed!
-> No virtual resolution support or not enough memory?
Falling back to system back buffer.
Following is the whole log info of DirectFB:
