Display Split Horizontally
Submitted by snowcamper on July 12, 2008 - 7:03am
Just installed, and live TV feed is clear, the sound is clear, but the display is split in two across my screen. It's a Hauppauge 350. I attached a screenshot, though the screenshot adds a black box in the middle of the screen that isn't there watching TV. Any thoughts on what is causing this and, more importantly, what I can do to fix? I'm still new to linux, so please be descriptive with your remedies!! Thanks.

Never seen or heard of this
Never seen or heard of this before. What did you do to get things working? Have you played around in the xorg.conf file? How are things hooked up?

what i did
i installed from the mythdora 5.0 installation originally, and things didn't work right at all. The feed was choppy. I then upgraded using the package manager, and then nothing worked at all. The screen for all the menus on the front end were all pixelated and split down the middle vertically (note the different split). So, then I read that I wasn't supposed to upgrade that way, reinstalled from the disc, and did the yum upgrade \*myth\*, and that got me to where I am now, with a clear picture and sound, but the screen split horizontally.
I tried playing with xorg.conf before upgrading everything - putting in values for someone who has almost the exact same system as me - but that broke everything, and I had to reinstall. I'm not really that confident messing around with xorg.conf, since everything else is working well and displaying well.
I have a Dell XPS 410 with some sort of ATI Radeon built in graphic card, a piece of crap Dell TV card that didn't work after I went to linux from Windows, a Dell E197FP monitor that doesn't seem to like linux either, though is working well now, and the hauppauge pvr 350 tv card hooked up via s-video/audio to a DirecTV box.
Here's my xorg.conf:

Ah I see now. You made it
Ah I see now. You made it sound like you were using the TV-out on the PVR-350 and not through a video card. Since you don't know what kind of video card is in the computer, choosing the ATI Radeon drivers wasn't good. Those drivers only work on certain video cards. But you do have a picture which is a start. Some things to try.
1) At xterm login as root and see what kind of errors are in the xorg log. Chances are your not using the driver to it's full potential or there is a problem.
cat /var/log/Xorg.0.log | grep EE
2) Edit your xorg.conf file with these changes. There is no need for the compiz stuff.
Section "ServerFlags"
Option "AIGLX" "off"
EndSection
Section "Extensions"
Option "Composite" "Disable"
EndSection
3) And if your plugged into both a monitor and a TV at the same time then you have to add this line into your xorg.conf file in the device section.
Option "OverlayOnCRTC2" "on"

Still seeing double
and I don't think it's the beers...
1) I Don't think there were any errors:
[root@nutbag mythtv]# cat /var/log/Xorg.0.log | grep EE
(WW) warning, (EE) error, (NI) not implemented, (??) unknown.
(II) Loading extension MIT-SCREEN-SAVER
[root@nutbag mythtv]#
Then I made the changes you suggested in 2) and 3).
Then I wouldn't use the
Then I wouldn't use the fglrx driver. Change that to radeon. Only thing is the tv out maynot work. I have a script that's been used only once which didn't work from what I hear but it's your only shot. It's /storage/misc/extras/xrandr.sh
If none of that works then you need to purchase a real video card like Nvidia. Anything say from an FX5200 - 6800 should be fine.

Thanks
Thanks for the online tech support today. I'll post a reply if anything ever gets working.
Ah Ha. I think I found our
Ah Ha. I think I found your problem. It seems the deinterlacer needs to be changed. This can be a PIA in 0.21. The older versions made it very easy to change this but now things are just a f***ing mess IMHO. Your gonna need to go into Playback Settings in Utilities/Setup -> Setup -> TV Settings - Playback -> 3rd screen. In that mess of things where you can change library files and filters from 1-5, there is an edit button and from there you can change the Primary deinterlace and Fallback interlace. God only knows which ones will work. You will have to play with things and see. Also on the 1-5 options you may want to play with those and move them around by changing the numbers off to the right and that will change their ordering. Man that whole thing is a huge cluster fuck. Try moving the option if rez > 0 0 -> ffmpeg & xvideo to the top first and then change interlace. Hope that helps. Here is the link I found for your problem. I would read all of it to be sure.

OK, got it, but...
Here's a screenshot of my settings that work. EXCEPT, every now and then, when I start up the frontend, it starts up all distorted with a vertical split down the middle of the screen. I then restart xterm, and it usually works. Any thoughts on why this is happening and/or how to fix?
Next task, trying to get the remote to actually change the channels on the DirecTV box! I'm going to try the procedure outlined at http://mythdora.com/?q=node/2603
Sounds like things still
Sounds like things still aren't perfect and may need more tweaking but things may never get right. Not sure why restarting xterm would have anything to do with it. Do you mean restart the frontend?
