I've build world with and then without
WITH_NEW_XORG, and in both cases I get
on X -configure:

(==) Log file: "/var/log/Xorg.0.log", Time: Sun Feb 23 23:03:06 2014

        radeon

        vesa

(II) [KMS] No DRICreatePCIBusID symbol, no kernel modesetting.
Segmentation fault at address 0x0

Fatal server error:
Caught signal 11 (Segmentation fault). Server aborting

or if I deinstall xf86-video-ati-7.2.0_1
I get:

(==) Log file: "/var/log/Xorg.0.log", Time: Sun Feb 23 23:04:07 2014
List of video drivers:

but then on X -config /root/xorg.conf.new -retro:


Fatal server error:
no screens found

I can provide more info, but perhaps
I'm just doing something very wrong.
I haven't followed the X developments
so I might be doing something silly.

I tried updating via pkgng, and then
rebuilding ports manually.

Will be grateful for any hint.

Thanks

Anton
