crystalbuntu 1080p resolution problem !
#1
I have problem with the resolution of my atv1 crystalbuntu with crystalhd !
I can not set it to 1080p and it always goes to 1366x768@60
xbmc shows 1366x768 @60 and also my tv which is a 52" samsung full HD too !
even though I dont have that resolution in my xorg.conf
any idea where the problem is ?

this is my xorg.conf :

Code:
atv@Crystalbuntu:~$ cat /etc/X11/xorg.conf
# nvidia-xconfig: X configuration file generated by nvidia-xconfig

check the xorg log to see if that config is actually being used or it's kicking back to some defaults.

In that log it says "(WW) NVIDIA(0): No valid modes for "1920x1080"; removing."

I'd suggest take a read of this thread, http://forum.xbmc.org/showthread.php?tid=70068 and pay particular attention to this section :

2. Finding what modes the TV says it supports in it's EDID.

From there you should find out the exact modes supported and then you can add them to the xorg.conf.

well I had seen and read that thread before and thanks for mentioning it again !
I found a weird solution !!!!
Now let me explain the situation :
my xbmc is connected to pioneer full HD AvReceiver lx-85 with HDMI then it is connected with 2 hdmi out to my samsung 50" and vivitek projector both full HD also support 1080p-24 !
when i start the xbmc only with samsung on it goes to 1360x768
if both are on it goes to 640x480 Confused
now i just find out that if I turn it on with only projection on it goes to 1080p but some times it misses the audio so I have to restart again !

how can I prevent the situation ? any idea ?

Replace HDMI cables. I had similar problems with a Denon AVR-4311CI connected to both a Samsung Full HD LED TV 50" and a Panasonic Full HD projector simultaneously. Replacing cables eliminated problems. Also check the Pioneer receiver inputs setup, as the receiver may be set to lower resolutions defined in defaults.
