splash during boot - sircube - 2010-07-13
Sam, any chance to have boot logo/splash while reaching X window?
Nice package BTW.

That's quite alright - I reckoned it deserve a one-stop explanation to get people running. That way, whenever anyone asks, they can be pointed at that post, and my internet notoriety is secured! I'd hoped to cover everything required for general use, but it looks like I missed the audio device. Oops!

Go to System->System->Audio Output->Audio Output Device and set it to iec958
(I have the same for Pass-through output device)
Thanks for that, Beto - I've updated my instructions with that.

Well, the obvious answer is to turn the TV on before the ATV. But you didn't say what type of connection you're using.

Yep.. that usually happens with X11. The problem is that X11 relies on EDID (http://en.wikipedia.org/wiki/Extended_display_identification_data) in order to set up the correct resolution, frequency, etc, and since the TV's off X11 does not receive that info and switches back to failsafe mode (most probably output through VGA jack).
One workaround I know of would be to tell X11 not to rely on EDID and manually set all the monitor's parameters on xorg.conf. (CustomEDID option)
I wouldn't personally recommend doing that since if you ever change the TV (and you don't change those settings), X11 will still treat that device as the old TV and might do some nasty things on it.
Maybe there's a safer workaround..
Hope this helps,
beto

I have captured the LCD TV's EDID and I'm using CustomEDID in xorg.conf
Besides if you want to have X started without having the LCD TV over HDMI turned on, then google around this parameter:
Code:
Section "Device"
...
Option "ConnectedMonitor" "DFP"
...
End Section- Sam.Nazarko - 2010-07-14
Just output EDID data to a file (by usng the Nvidia tool in Ubuntu desktop), then edit xorg.conf so you are pointing to the EDID file (google for how to do this)
Any problems just edit your XORG.conf / restore a backup of it / run nvidia-xconfig or restore the image

I have an AppleTV with pin87's image that I've had to rebuild from image twice now because for whatever reason, the Component output starts outputting a non 480P signal (which is what my CRT RPTV is capable of using). I hooked it up to another TV that handles 1080i Component and that is not syncing either. I don't know what the sync / resolution is being output now, but my xorg.conf file is unchanged from my setup like this:
Code:
Section "Screen"
Identifier "Screen0"
Device "Device0"
Monitor "Monitor0"
Option "UseDisplayDevice" "TV"
Option "TVOutFormat" "COMPONENT"
Option "TVStandard" "HD480p"
Option "TVOverScan" "0.80"
DefaultDepth 24
Option "NoLogo" "True"
SubSection "Display"
Modes "720x480" "640x480"
Depth 24
EndSubSection

I don't want to have to rebuild the drivers every time this happens -- and it seems to be happening because my TV is indeed turned off when I am doing some atv updates or something and reboot the atv.. So i'm guessing the nvidia drivers don't see the TV and default to VGA (or something non 480P). I don't know how to pull the EDID off my TV to force it as someone suggested above. What are my options here? Surely I can revert back to 480P somehow without rebuilding the image and updating everything again a 3rd time?Code:Section "Screen"

dmesg or xorg log will tell more info about what is going on.
to restart X11 -> 'sudo /etc/init.d/gdm restart'

Thanks one more time Sam.
I solved...

Everything I am seeing from searching google involves using the NVIDIA settings manager through the GUI. I'm using pin87's image that doesn't come with the desktop and I have no ability to VNC to the machine (that I could tell) so I can't figure out how to do this thorugh command line to force the display to my crt rptv.
