Fixing tearing issues – random tip
UPDATE2: With VDPAU enabled, you’ll also probably get tearing unless you disable composite in your X.org conf:
Section "Extensions" Option "Composite" "Disable" EndSection
UPDATE: The below fix is included as a toggle box in the advanced features in the mythbuntu control panel anyhow.
Some info about what to do if there is picture tearing..
Add the desired configuration to /etc/sysctl.conf to apply the values at startup.
$ cat /etc/sysctl.conf
dev.rtc.max-user-freq = 1024
