Re: Portrait display mode

Diagramatically, the fb-based console looks something like this:

Console -> fbcon -> fbdev -> graphics-capable hardware

Rotation is done at the fbcon layer. fbdev on the other hand is just an
abstraction of the underlying graphics hardware.  It is fbdev that is
actually used by fb-based applications, such as Xfree86.  fbdev does not
know about display orientation, but Xfbdev does, and so can fbcon.

What about applications compiled with GTK+ target linux-fb or similar toolsets?
If I understand it right only the fbcon layer should be used (if possible) to be
on the save side.

What does a rotation unter X bring as long as the console doesn't? Okay for

This is actually what triggered me to submit the patches, it is quite
disconcerting to switch from a rotated Xfree86 display to an upright
console.

Okay I'm not so much interested in Xfbdev than in fbcon. Can you transferred
your code to the generic part as Geert Uytterhoeven already asked. I could help
test patches against kernel 2.4.19. And what about kernel 2.5, I've read of a
feature freeze soon?
