OK, there are three problems related to external screens, with these packages installed. Let me know if you want them to be filed separately:

1- after connecting the external monitor (even if it's not turned on or active) some windows are painted incorrectly, with bits of the desktop background or other windows showing through.

2- after setting the display to external-only and using it for a few minutes, it flips back to side-by-side mode. this happens repeatedly. I can use Display Settings to go back to the external monitor but it does not stick.

3- after 2 occurs, fn-f7 no longer seems to have any effect.
