Presumably you recognized your bug where you said '180' but you really meant '90' (rotating 180 will cause the display to be upside down).
I built DirectFB from the git repo (v1.7) and didn't have the same issues. Mostly I've been trying to get to an accellerated solution but it seemed to work as I would expect. I'm also running on ARM rather than x86 but that shouldn't matter. Do you have a buildable piece of sample code that doesn't work? --Chuck On Wed, Aug 22, 2012 at 12:04 PM, Karim 'Kasi Mir' Senoucci < direc...@tvetc.de> wrote: > Hello everyone, > I don't know if anybody's reading these lists anymore (my last question > didn't get any replies whatsoever), but I'll try it once more: > > I see the nice example of a sideways window on directfb.org ( > http://www.directfb.org/**screenshots/LayerWindowRotate.**png<http://www.directfb.org/screenshots/LayerWindowRotate.png>), > and I wouldn't even need something that complicated: I want to turn the > whole display (because the monitor is used in portrait orientation) by 90 > or 270 degrees, so that I get a 1080x1920 display instead of a 1920x1080 > one. > > I use dfb++, but those are only wrappers for the directfb calls, so that > shouldn't be the problem, I think. > > At the moment, I pass "layer-rotate:90" via argc/argv which seems to be > recognized fine, but then I get: > > (!!!) *** UNIMPLEMENTED [dfb_surface_create] *** [surface.c:179] >> (!!!) *** UNIMPLEMENTED [dfb_surface_reconfig] *** [surface.c:525] >> > > and the display remains in landscape orientation.
