Still with my sDVO card with HDMI and my 1080p HDTV...
I still have the TV sporadically giving me the EDID. So I have those
ModeLine and PreferedMode lines in my xorg.conf.
I now have another issue.
Quite solidly, with a very few exceptions, I do not get any picture.
X starts, the X application starts, my TV gets out of the blue screen,
but I have no picture, just a black screen.
Once in a while I get a bleep of picture.
I fail to see errors in the logs.
I tried the 2 HDMI sockets on the TV.
The cable is supposed to be clean/good/expensive enough to support the
1080p frequencies and bandwidth (Belkin PureAV).
Moreover, I tried to set the resolution to something lower, like
720x576, a mode that is apparently native to the TV, but I get stuck
with X still going to 1920x1080, even when using PreferedMode:
(II) intel(0): Output TMDS-1 using initial mode 1920x1080
I am open to any suggestion.
* change the TV (same model or other brand) - not the preferred
* change the sDVO card (bought in the US, I am now in the UK...)
* change the HDMI-HDMI cable
* test anything you want
* provide any output you want
Here are the X files when I get a black screen:
Here are the X files when I get something solid:
Note that using the EDID info or the ModeLine make no difference.
This is on an Ubuntu Gutsy install, 64-bit Core 2 Duo, Intel DG965WH
motherboard, up-to-date BIOS from Intel.
Thanks for any help/pointer.
