Description of problem:
Sometimes flash (using the adobe Flash plugin) fail to run. The kernel generates the following error:
Jun 15 16:43:31 delos kernel: composite sync not supported
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Attempt to view any video on youtube.com.
Video fails to play.
kernel: composite sync not supported
This worked in Fedora 12 (and 11 and 10)
I reviewed this bug report and I don't think there is enough information to determine the source of the problem. The error message you are seeing is a common message that is generated when the X server reads the monitor EDID information.
As this seems to be a bug report against the Abode Flash Player, which is not supported here, I am marking the bug as CLOSED/CANTFIX.
I encourage you to look at the page at the URL below which details how to setup flash to run inside the nspluginwrapper.
For additional support, please try either the #fedora channel on freenode or Adobe support.
