Hi,
I just had the same problem, gtk reports wrongly that there's a problem with
the layer, but it could be a problem with the input device.
GTK+ needs a keyboard and mouse, otherwise it complains and refuses to
start, the problem is that the DirectFB backend reports this lack of input
device as a layer issue instead of an input issue.
If you have disable-module=keyboard and/or disable-module=ps2mouse in
directfbrc, remove them. This should solve it.
Regards,
