[maemo-developers] [maemo-developers] Re : Problem with Enlightenment [Evas] on Maemo 2.0

[From: Sebastien Bourdeauducq]

Are you running this under X, or straight on the framebuffer ?
In the latter case, the initfb program at
http://lekernel.lya.eu/opie770.html should help.

It is also possible that you get this problem under X because evas
uses directly the framebuffer in some cases to gain some speed. Try
disabling acceleration.
