Hi all,
I'm new to Knoppmyth/LinHES, though fairly experienced now with MythTV installations. This is the third MythTV distribution I've tried and, so far, the one I like the most. (I've used Gentoo and Mythbuntu 8.10 and 9.10 before.)
Anyway, onto the issue at hand. With the other distributions, I've used the following modeline to drive a 16:9 CRT TV directly via RGB SCART from the VGA socket (a well documented method around the web).
Code:
ModeLine "PALi-ws" 19.750 1024 1056 1152 1264 576 581 586 625 interlace composite
The video card is an integrated ATi Radeon X200 (known as RC410 by the xf86-video-ati / radeon driver) and is loaded with the 'ForceMinDotClock' option set at 13MHz.
The problem is, the TV isn't syncing with the image properly. The closest I've got to this working is with the odd and even fields top and bottom of the screen respectively (rather than being scanned alternately as they should be). This made me think the 'interlace' option was being ignored, so I tried removing it, then the picture was incomprehensible. Likewise, I tried removing 'composite', which also changed the image, but not for the better.
I've also tried all combinations of adding ±hsync/±vsync to no avail.
Something which may be relevant is that immediately after installation, X was outputting a mode my monitor couldn't display, despite the monitor's settings apparently being detected and written to the X.org file. I fixed this by deleting the settings in the X.org file, so X.org detected the settings automatically on startup. (This isn't the only issue I had with installation: I'll post that elsewhere though.)
Any help would be greatly appreciated. I really want to get LinHES running!
Edit: the complete xorg.conf is
here. I've also uploaded a log file
here from Xorg running with this xorg.conf.
Edit 2: I've just noticed this is the wrong forum, sorry! Could a moderator move this to the LinHES hardware forum please? Thanks!
