An update: I found this which appeared to describe my problem: https://www.qubes-os.org/doc/intel-igfx-troubleshooting/
I checked /var/log/Xorg.0.log and found the "reverting to software rendering" line. I then followed the recommended fix for EFI by adding " i915.preliminary_hw_support=1" to the xen.cfg file. I then rebooted but the boot failed. Since the drive was encrypted I could see no way to get back to change xen.cfg back to the original. So I used a live LM 19.2 stick to see if I could access the file from it. It did ask for my encrypt password but would not access the drive. I finally had to re-install the Qubes OS. No loss, except the time involved. But I can still not watch videos.
