DualHead-hack for iBook breaks radeonfb
Hi all,
(slightly OT, it's not Debian-specific, but I guess there are some
competent people around here)
the recently be the german C't-magazine published iBookScreenEnhancer[1]
(said Dual-Head hack) gives me quite a few headaches :-(
The hack worked fine in OS X, but since then I'm always getting
"radeonfb: Failed to detect DFP panel size" when booting Linux, leaving
me with a disfunctional X-server (but at least a working console,
although the backlight stays on, even when sleeping <sigh>).
And no, Alt+Apple+P+R didn't help either :-(
One suspicious thing is, that there is no EDID-property in
/proc/device-tree/@f0000000/ATY,BeeParent@10/ATY,Bee_A/
(there should be one, right?):
$ ls /proc/device-tree/pci\@f0000000/ATY,BeeParent\@10/ATY,Bee_A/

Here's a complete .tar.gz of /proc/device-tree:

Any hints welcome!

Microsoft isn't the answer. Microsoft is the question, and the answer is NO.
