Full Version: Problems with default screen resolutions
You're currently viewing a stripped down version of our content. View the full version with proper formatting.
I'd appreciate some help about an odd problem I have here.

First, my details:
AMD Athlon 4850e, 4GB RAM, Geforce 9400 with 1 GB
Ubuntu mini, kernel 2.6.24-24
XBMC downloaded and compiled directly from svn, revision 20937

Since my TV, LCD Philips 42FPL9903, doesn't deliver correct EDID-information and the default resolutions and refreshrates did not work for me, I had to define my own modelines in xorg.conf. I finally got the right one for correct 24p output and also for 50 Hz PAL: http://pastebin.com/m4bea73b9

My problem is, although both modelines are working, XBMC doesn't let me choose both of them (only one, and that is always the first in xorg) and does not autoselect them.
Here's a debug log of a normal start:

In the screen settings XBMC offers me many "DEFAULT...."-resolutions I do not want to have. Where does it get them from? The problem is, these default-resolutions also include [email protected] and [email protected], which are not working correctly for me. I would like to use my resolutions defined in my modelines.

I hope I could describe my problem properly and someone could give me a hint. Huh
Mmmmh, I couldn't find a solution in this thread.
I've enabled Auto-Refreshrate in XBMC.

I'n the screen resolution settings in XBMC I can choose many different resolutions:
"PAL 4:3"
"PAL 16:9"
"NTSC 4:3"
"NTSC 16:9"
"480p 4:3"
"480p 16:9"
"720p 16:9"
"1080i 16:9"
"default: 1920x1080 @ 24.00Hz"
"default: 1920x1080 @ 50.00Hz"
"default: 1920x1080 @ 50.00Hz"
"default: 1920x1080 @ 60.00Hz"
"default: 1920x1080 @ 30.00Hz"
"default: 1920x1080 @ 25.00Hz"
"default: 1680x1050 @ 60.00Hz"
"default: 1600x1024 @ 60.00Hz"
........many more defaults..........
"default: 320x240 @ 60.00 Hz"
"1920x1080 @ 24.00 Hz (Full Screen)"

If I choose automatic, XBMC always uses "1080i 16:9".
If I choose one of the default 1920x1080-modes, my TV doesn't display them correctly. The screen is filled only on the left half and flickers.

I guess "1920x1080 @ 24.00 Hz (Full Screen)" is my defined modeline from xorg.conf, which I named "1920x1080_24". Using this, my 1080p mkv-files with 23.976 fps play absolutely smooth. But divx-files (50Hz) suck of course.

I don't know why my second modeline from xorg.conf named "1920x1080_50" is not displayed in the XBMC-list. And I wonder, how I can exclude those default-modes. Sad

I don't understand why, but when XBMC reports that it isn't always really in that mode. You can bring up nvidia-settings, or look in the hardware status in XBMC for 60hz/30hz to figure out if it is really interlaced.

look here dude


Ok. I should have read the end of this thread mre carefully... Rolleyes
I had to delete my guisettings.xml. Now XBMC seems to take over the modelines from xorg and uses these in the "default...-modes".

Why is this nowhere else documented? I spent so much time for this. Shocked
If you want to prevent all of the default modes from being displayed in xbmc and only display your modelines then you need to add the following lines to xorg.conf:

Option "UseEDID" "False"
Option "ExactModeTimingsDVI" "True"
Option "ModeValidation" "DFP-0: NoVesaModes, NoXServerModes, NoPredefinedModes"
Option "DynamicTwinView" "False"

I may have missed something from the ModeValidation line but these options are all explained on the nvidia site. I am assuming that you are connecting via hdmi if not you will need to change the "DFP-0" to your requirements.
