emc crashes after 2.4.7 update

This is a new problem. EMC2 splash screen comes up, then this debug screen.

I updated emc2 to 2.4.7 this AM.

is it wrong?

Based on advice I got from IRC, I downgraded the x server, now it works.

(JT is that you?)

Run the update manager in Ubuntu again. There just happened to be an update from Ubuntu that broke X today (or yesterday). There should be a fix now in the Ubuntu update manager.
