I know this is question is more suited to a forum like Ubuntu stack exchange. But this form is so much easier to read and deal with…
After upgrading to 23.10 the display will freeze randomly.
I can get the display to come back, by disconnecting my second screen.
The system as a whole is unresponsive when it happens. But any video I was playing will continue to play and the sound will come through (can’t turn down the sound though). Also if I use the keyboard shortcut to open a terminal (ctrl + F6… I think). The terminal will not display for a few seconds. And I’m unable to go back to the gui (F7).
This last time it happened, I decided to wait it out. I unplugged all peripherals (including my second display). And this is what I got:
It took a bit for the device to refresh and come back alive. For example, this screenshot was taken using spectacle. It took 5 seconds after pressing the hotkey to bring up spectacle for the gui to respond.
Here is the Journalctl of the last time the freeze happend: log
I found this bit interesting:

Any help would be appreciated.
