whatever i valid with xrandr is not really do on my tv
although xrandr say it's good , my tv always report 1202x670 50hz
I tried with and without xorg.conf
My last kernel working is linux-2.6.36-gentoo-r6.
If, i tweak drm_edid.c from kernel-2.6.39-gentoo-r1 like this:
--- drm_edid.c 2011-06-10 22:37:36.605848000 +0200
+++ linux/drivers/gpu/drm/drm_edid.c 2011-06-13 13:04:43.136786102 +0200

+ if (drm_edid_block_valid(block + (valid_extensions + 0) *

valid_extensions++;
break;
}
that work good like before but i'm not sure that is safe.

I can post logs here too , just tell me.
See you

Hello
I just change from nvidia (nouveau) to ati (radeon)
for some reasons of noise .
And it's the same probleme with wrong edid block 1.
My tweak of drm_edid.c work again whatever it's nouveau or radeon
but again , i don't know if it's safe.
