nvidia-graphics-drivers-545 package fails to launch graphical session with latest linux 5.15.0-107 update

[Msd]

No graphical session can't be launched after the update to linux 5.15.0-106 and then linux 5.15.0-107 today with nvidia-graphics-drivers-545 installed.

I can see this problem in syslog :

```
lightdm[2367]: modprobe: FATAL: Module nvidia not found in directory /lib/modules/5.15.0-107-generic
```

We can see there is no linux-modules-nvidia-545-5.15.0-107-generic :

```

Status changed to 'Confirmed' because the bug affects multiple users.

[André Hertler (andreaxis)]

Can confirm. It has affected all hosts that we are supporting at work. Work around has been to install Nvidia driver version 535 for now.
