setting up a new mythbuntu 14.04.1 system with an nvidia
GT730 video card (nvidia 331 driver). I am trying to get
rid of the tearing. I have been following the suggestions
at <a moz-do-not-send="true"
href="http://www.mythtv.org/wiki/Frame_display_timing"
target="_blank">http://www.mythtv.org/wiki/Frame_display_timing</a>,
but I am not having any success. I have added the udev
rule to change permissions on /dev/rtc and verified that
they are correct. I have added an entry to
/etc/sysctl.conf to set the max-user-freq and verified
that it is correct.<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/55-mythtv.conf, or
/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>
