Unity is counterproductive to kodi as it is a compositing manager, which uses compiz that implements a non standard compositing exteions we cannot disable.
For nvidia see: http://wiki.openelec.tv/index.php/Config..._xorg.conf
THX for Link,
1 what is special about those modelines or which option does the trick ?? ... because right now it uses EDID as posted from xrandr above and it has the same modeline for 24Hz in the linked xorg
ModeLine "1920x1080_24" 74.250 1920 2558 2602 2750 1080 1084 1089 1125 +hsync +vsync
or should I just add the 23.976 modeline which is missing in my EDID ?
When I add
ModeLine "1920x1080_23.976" 74.175 1920 2558 2602 2750 1080 1084 1089 1125 +hsync +vsync
X adds it twice:
"1920x1080_23.976" : 1920 x 1080 @ 24.0 Hz (from: X Configuration file ModeLine)
"1920x1080_24" : 1920 x 1080 @ 24.0 Hz (from: X Configuration file ModeLine)

Starting with -rate 23.974 (and up) xrandr uses the same mode (x281) as with rate 24 which is our new 23.976 mode from Xorg (I guess because it has the higher clockf = 74.175.
Rate 23.973 and below use the built in mode x284 from EDID (CAE Mode32) which has 74.16Mhz.
