Control Alt Delete

[Christopher Thacker]

What is the Qubes version of "Control Alt Delete"?

If I leave Qubes and the screen goes black upon my return 5 minutes later, then I can't interact with anything on the laptop screen. My mouse works fine but the Qubes VM does not respond to any mouse input. I even unplugged and replugged my mouse.

Even the little icons in my lower left and lower right do not respond. It is as if the entire screen, including the Qubes VM manager, freezes. In such situations manually restart the laptop.

What is the "Control Alt Delete" mechanism so i can get a "task manager" to see what is happening?

Thank you.

Ctrl+Alt+ESC then click

Then proceed to see what guest vanished from the screen.
After that, in the run dialogue for that guest, run something to bring back the display of it.

Are only AppVMs frozen? (Can you still interact with dom0?)

Can you switch to tty2 (Ctrl+Alt+F2, and Ctrl+Alt+F1 to get back) and
log in there? If so, maybe you can figure out what's gone wrong via
command line tools?

I will do so next time it happens. It isn't my everyday laptop, so it will be a week or two before I require Qubes.

I will try that next time. Nothing on the screen works. I can still move the mouse curser anywhere but nothing happens when I click. It is very strange. It is an Asus x750j laptop running Qubes 2 on an ssd instead of the original hdd. Otherwise it works well.
