Hello everyone,
I've already ask about this on the users mailing list, but perhaps this
is more of a "dev" issue. I have tried (with 1.3.2 and 1.4.17, both on a
Gentoo linux running the not all that new 2.6.28.7 kernel) to get the
"layer-rotate" parameter to work for a 90-degree rotation, but somehow I
can't get it done.
I'm calling my program with
--dfb:layer-rotate=90,mode=1280x1024,depth=32,pixelformat=RGB32
I'm using the uvesafb frame buffer for graphics output. I have only a
few graphics and text on my display so I don't really need hw
acceleration, plus I have three different Mini-ITX boards in use here
with three different Intel Atoms (410, 525, and 2500).
Unfortunately, the "layer-rotate" parameter does not work here; I get
the following log output:

It this parameter working at all? If so, what am I doing wrong? Is there
another way to get the whole display (primary surface) to rotate 90
degrees?
The program is written in C++ and uses DFB++, by the way:
[...]
DirectFB::Init (&argc, &argv);
dfb=DirectFB::Create();
prim_layer=dfb->GetDisplayLayer(DLID_PRIMARY);
if (prim_layer==NULL)
PrintLog("Couldn't get primary layer");
dfb->SetCooperativeLevel(DFSCL_EXCLUSIVE);
//prim_layer->SetRotation(180);
//prim_layer->SetCooperativeLevel(DLSCL_EXCLUSIVE);
base_surface=prim_layer->GetSurface();
if (base_surface==NULL)
PrintLog("Couldn't get base surface");
SetVideoParameters();
keyboard=dfb->GetInputDevice(DIDID_KEYBOARD);
if (keyboard!=NULL)
keyboard_buffer=keyboard->CreateEventBuffer();
dsc.flags = DSDESC_CAPS;
DFB_ADD_SURFACE_CAPS( dsc.caps, DSCAPS_PRIMARY);
if (use_system_memory==true)
DFB_ADD_SURFACE_CAPS( dsc.caps, DSCAPS_SYSTEMONLY);
else
DFB_ADD_SURFACE_CAPS( dsc.caps, DSCAPS_VIDEOONLY);
DFB_ADD_SURFACE_CAPS( dsc.caps, DSCAPS_DOUBLE);
DFB_ADD_SURFACE_DESC(dsc.flags, DSDESC_PIXELFORMAT);
[...]
If you need any further information, feel free to ask.
Thanks in advance
