Public bug reported:
I've started observing this bug since i've started using NVidia's
additional drivers (yesterday). Before that I was using nouveau, which
happened to use the builtin Intel GPU and not the NVidia card.
I have an external monitor which I usually connect to the laptop. I have it
configured so it's the only screen when it's connected. When I unplug it,
automatically the laptop's builtin screen turns on, and when I plug it, the
laptop's builtin screen turns off.
This has worked just fine until yesterday. Then I switched to NVidia's
proprietary drivers.
Now the problem, 100% systematically reproducible, is as follows:
- I disconnect the external screen (and external keyboard and mouse), move my
laptop and start using it alone. At the beginning everything works fine, then:
- from time to time (every few minutes), the system seems to freeze:
- mouse cursor doesn't move. Nothing responds to touchpad movements or clicks
- nothing apparently responds to keystrokes, such as alt+tab to switch
window, or Ctrl+Alt+T to open a terminal. I'm not sure this ever happened while
I was typing and had a focused window where to type, so I cannot tell for sure
it wouldn't respond to typing
- no signs of abnormal CPU consumption, though, nor of disk activity
- hitting ctlr+Alt+F1 does work and immediately brings the virtual console
- hitting ctrl+Alt+F7 brings the graphics screen again and it works, that is,
it fixes the issue, reesstablishing normal functioning
- unless it happens again.
The first time I observed it (this is the second), this also happened:
- then I plug in the external monitor again. It turns on, shows the screen
output as expected; the builtin screen turns off, everything looks normal
- except the system is frozen again
- and this time not even Ctrl+Alt+F1 work. Completely frozen. No way out except
a hard reboot
- unplugging the external monitor doesn't fix the issue, either
