[RCC <1292830@xxxxxxxxxxxxxxxxxx>]

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):

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.)
