I built qte 4.5.1 on a powerpc with the directfb driver.
I'm using the latest directfb 1.4 with a custom gfxdriver (Fujitsu MB8629x +
FBDev).
When I launch the qt demos, like
deform -qws -display directfb
I get
(!) Core/SurfBuffer: Buffer allocation failed!
--> Not supported!
Activating debug output, it seems that the negotiation for a private
preallocated buffer failed.
the buffer allocation fails when QTe tries to use a:
* preallocated buffer
* for GPU use
I don't know how GPU buffers should work, but I've seen that some
drivers add a GPU preallocated buffer pool. This is not used by default
on fbdev, however.
How can I fix it?
Thanks
