[CH7315] SDVO TV out not supported
Last modified: 2009-02-15 19:51:16 UTC
I'm using latest stable release of xorg + git version of i810 driver from modesetting branch (from 13th February 2007). I can't get working video with it, I've tried without xorg.conf file as well as with xorg.file which is working great with i810 v 1.7.4. In all cases when using modesetting branch I end up with not supported video mode form LCD monitor.
[aflinta@warp ~]$ sudo dmidecode |grep 965
Product Name: DG965WH
my monitor is LCD Samsung 173s
Below attached Xorg logs runnig without and with xorg.conf and xorg.conf file.

This appears to be due to a failure to DDC. Need to try fixing the I2C issues I noticed in the X Server a while ago and see if that helps.
Sorry about the phenomenal bug spam, guys. Adding xorg-team@ to the QA contact so bugs don't get lost in future.
On re-review, it's not DDC (or at least, not just DDC). Could you describe what video output connectors are available on your machine, and which you have monitors connected to?
Sure, I have Intel DG965WH motherboard with ADD2 card (prolink PV-CH7315 (N16TDS)-F http://www.prolink-usa.com/item_disp.php?upc=2006886907073 ).
I have only Samsung 173s connected to VGA output on motherboard, I've tried also to connect TV via S-Video cable, but has no impact on logs or display behavior at all. I'm not using HDMI output.
Using latest intel driver 1.9.93 (RC3) I've made some testing and here are the results:
a) DDC isn't working (no matter if I have ADD2 card or not). Maybe it should be in separate bug? Does it exist or should I create the new one?
b) If ADD2 card is not present in the system I can switch between text terminals and graphics several times without any problems). But if I put ADD2 card into computer (without connecting anything to it), X starts without problems and I have video on VGA output, but switching to text mode causes that monitor goes into suspend mode, switching back to graphics causes X server segfaults (and monitor is still blank). The only thing I can do is switch back to text console and type (as blind men) "reboot" with hope that it will work ;)
Log from this session is in attachment.

Tested with 1.9.94 (2.0 RC4) with the same results as in previous versions :(
TV-out SDVO cards are not supported currently, and will likely cause all sorts of problems. See the mailing list archives for information on some development being done to support SDVO TV-out, which hasn't been merged in yet.
Updating the description.
The DDC issue is a dup of bug# 10694. If I can still get a response from you and this is still a pain for you, please reopen bug# 10694...
Added some code to master for SDVO TV-out, but it doesn't work on my hardware yet. The BIOS doesn't light up my card, so I'm working blind trying to figure out how to program it right. If someone has SDVO TV output working from the console, it would be interesting to see the /var/log/Xorg.0.log, particularly with i830_sdvo_dump_regs() added to the init path.
Artur, have you tried with current git master or 2.4.0 release?
Eric: I have SDVO TV out, and I can see the console and BIOS splash on the TV.
What do you need to know?
I've tried with 2.5.0, no luck
can anyone try with latest GIT?
This needs to be tested against recent drivers and with ModeDebug log.
Can you test my patch on Bug #17776?
