Would I be correct in thinking that the Nvidia-510 driver turned this into bug 1964037 and bug 1959888 instead? If so then we could just declare "Won't Fix" for nvidia-470. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu.

Great, thanks for the explanation. So blaming just the nvidia-drm kernel module seems most reasonable right now. It is what's crashing after all. Most likely the fix will come in the form of a new Nvidia driver. Please try apt install nvidia-driver-510 or via the 'Additional Drivers' app. You

I'll reproduce later today after hours. Will also try to install 22.04 to see if it helps. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1960865 Title: System freeze when plugging USB-C monitor

@vanvugt - USB-C port seems to be wired to NVIDIA GPU on this laptop. I cannot use the monitor, if I switch to Intel GPU (`prime-select intel`) - it doesn't even identify that a monitor was connected. -- You received this bug notification because you are a member of Ubuntu Bugs, which is

This sounds like a simple bug in nvidia-drm-470 or kernel 5.13. Both have been upgraded in Ubuntu 22.04 already so there's a chance this issue is already fixed. Still, please follow the instruction in comment #7 because I would like to understand more about the system. ** Changed in: mutter

The strange thing to me is that Nvidia shouldn't be involved here. A USB-C port is likely to be wired to the Intel chips only. As a DisplayPort the USB-C is wired to the Intel GPU. And gnome-shell by default will use the integrated Intel GPU only for the desktop. Please reproduce the freeze
