Just wanted to give my thanks for this fix and also make an enquiry. I'd also like to thank everyone in this thread for making no noticeable usage of the colloquialism, "automagic". ****, that phrase annoys me.
I've got a Samsung HDTV with 100hz, that I use as my PC monitor. It recently occurred to me that the reason videos looks so jumpy, is due to:
a) most videos being between 23.9 to 25 FPS
b) my monitor's refresh rate being stuck at 60hz (30 FPS)
c) my TV trying to kick that up to 100hz (50 FPS).
This resulted in most videos going crazy at 1 second intervals, with any motion on screen becoming jumpy. Forcing 50hz modesetting with xrandr has fixed the issue.
Now, for my enquiry.
I'm still on 9.04 and have the following in my xorg.conf:
Yet no 50hz option is available in xrandr or xfce4-display-settings.
Identifier "Configured Monitor"
Modeline "1920x1080_50.00" 141.45 1920 2032 2232 2544 1080 1081 1084 1112 -HSync +Vsync
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
Modes "1920x1080_50.00" "1440x900" "1280x1280" "1280x1024" "1280x960" "1152x921" "1152x864" "1024x768" "832x624" "800x600" "720x400" "640x480"
Additionally, I don't have a graphical login manager, I just use login and, "startx", manually, so I can't do the gdm init fix
I could create a script with the relevant xrandr commands and add it to my autostart folder, except in the past, when I've added scripts that alter modesetting, to xfce4's startup process, I've had xfce components like xfce4-panel crash, making that an undesirable fix.
Cheers in advance.
