I'm setting up a new mythbuntu 14.04.1 system with an nvidia GT730<br>
video card (nvidia 331 driver). I am trying to get rid of the<br>
tearing. I have been following the suggestions at<br>
<a href="http://www.mythtv.org/wiki/Frame_display_timing" target="_blank">http://www.mythtv.org/wiki/<u></u>Frame_display_timing</a>, but I am not<br>
having any success. I have added the udev rule to change<br>
permissions on /dev/rtc and verified that they are correct. I<br>
have added an entry to /etc/sysctl.conf to set the max-user-freq<br>
and verified that it is correct.<br>

I have better luck with the 304 driver, and tearing with the 331.<br>

Did you disable composite?<br>
<br>
Run sudo nvidia-xconfig --no-composite<br>
OR, add this to /etc/X11/xorg.conf or a file in /etc/xorg.conf.d:<br>
Create file /usr/share/X11/xorg.conf.dG/<u></u>55-mythtv.conf, or<br>
/etc/X11/xorg.conf<br>
Section "Extensions"<br>
Option "Composite" "Disable"<br>
EndSection<br>
NOTE This is incompatible with unity desktop in 13.04 and later<br>
You will have to install and use xfce desktop manager instead of unity<br>

I have:<br>
Section "Extensions"<br>
Option "Composite" "Disable"<br>
EndSection<br>
<br>
in /etc/X11/xorg.conf. No difference.<br>
I cannot run nvidia-xconfig. It crashes. There is a bug entered for this on launchpad.<br>
