I have done some more investigation and it seems that in 1.2.x it does a Flip just before exiting. This means it Pans Display to the bottom half of the FB which is cleared.
In 1.0 (and the fbdev module) I believe it panned back to 0,0 before exiting. Is this true? In which case I presume I could solve this by panning back to 0,0 in my Release functions of my devmem based driver? Is this an issue for davinci driver as well? Cheers Dan -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Daniel J Laird Sent: 2008 Oct 10 09:06 To: directfb-dev@directfb.org Subject: [directfb-dev] Layer Clearing at shutdown in DFB 1.2.x I have found a difference between DFB1.0 and 1.2.x regarding shutdown. I have a /etc/directfbrc file as follows: mode=720x480 pixelformat=ARGB no-vt-switch system=devmem video-phys=0x02553000 video-length=4902912 init-layer=0 layer-bg-none init-layer=1 layer-bg-none When I start up the layers do not get cleared (as specified) and this works fine for DirectFB 1.2.x However a difference is that when I call Release on the main DirectFB instance in DFB 1.2.x the layer gets cleared. However on DFB 1.0 this did not happen. I have put a debug trace at bottom of this mail. Does anyone have any ideas on how I could stop the clearing of the screen in DFB 1.2.x on shutdown. A key difference is that on DFB 1.2.x we use devmem system whereas on 1.0 we built on FBDev. But any clues as to why the layers are being cleared when I call dfb->Release would be apprecated.
