Problem on new Ubuntu 22.04

[Thomas Sehrt]

There is a work-around, but unfortunately not the final solution.

My system information:
kernel release
user@linux-laptop:~$ uname -r
6.2.0-32-generic

kernel version
user@linux-laptop:~$ uname -v
#32~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Fri Aug 18 10:40:13 UTC 2

Check that the DisplayLink device is recognized on the USB bus
user@linux-laptop:~$ lsusb -d 17e9:
user@linux-laptop:~$

DisplayLink is not working. Now I reboot the system within the recovery mode.
GNU GRUB version 2.06
I choose from the lst:
Ubuntu, with Linux 6.2.0-31-generic (recovery mode)

Now all works fine.
user@linux-laptop:~$ lsusb -d 17e9:
Bus 004 Device 003: ID 17e9:6006 DisplayLink Dell Universal Dock D6000
user@linux-laptop:~$

The system information is identical to above. Why is the kernel release
6.2.0-32-generic
running and not
6.2.0-31-generic
as slected from Bootloader?

After several boots the original mis-behaviour is back.

Maybe can this description help to find out what the real root cause for disappearing of the functionality of DisplayLink is.
