On a similar, perhaps related note, when using the touchpad, (rather than the USB mouse) I often lose responsiveness of the pointer (happens every 10-20 minutes, at least) and I have found that the same workaround (switching to the F1 virtual terminal and back) restores the use of the touchpad. Anyone know if there a bug report for the touchpad issue already?
-----------------------
Thanks everyone.
Here's some details from my system:
(note: I did an apt-get dist-upgrade + reboot about 24 hours ago and that didn't fix anything. I'll try again after posting this, but I wanted to capture the system as-is first.)

I have repeated this issue multiple times.
I can confirm the workaround (Ctrl+Alt+F1, then Ctrl+Alt+F7).
I have the following HP Envy 15t with Nvidia 740M (from Costco): reviews. costco. com/2070/ 100070028/ hewlett- packard- hp-envy- 15t-quad- 1080p-laptop- intel-core- i7-4700mq- 2-4ghz- reviews/ reviews. htm
