The Adobe Flash plugin has crashed. Or plugin-container: Fatal IO errHave you been seeing this?or 11 (Resource temporarily unavailable) on X server

Have you been seeing this?

Or especially if you have been getting this error:

plugin-container: Fatal IO error 11 (Resource temporarily unavailable) on X server

Well no worries, here is the solution for your problem.

You probably have a file that looks like this:

# cat /etc/adobe/mms.cfg
#Hardware video decoding
EnableLinuxHWVideoDecode=1

Just edit the file to look like this:

# cat /etc/adobe/mms.cfg
#Hardware video decoding
OverrideGPUValidation=false
EnableLinuxHWVideoDecode=0

Your problem is solved.

Hope that helps.
