Hey,
since I've also encountered the bug, I've bisected the range and found
the offending commit to be 648dd7aa1f69 in noble.
I don't have any knowledge about the kernel, this was even the first
time I compiled a kernel, so I don't really know what's going on, except
that the problem has to be in
This issue could be reproduced at 6.8.0-50-generic and 6.8.0-51-generic,
I could not reproduce it at 6.8.0-49-generic kernel.

same here, a recent upgrade appears to have introduced the extra display

/dev/dri/card0"
```
this deletes the extra device automatically and makes the extra display
The diff is too large to find anything obvious, but hopefully someone
can just bisect between the Ubuntu-6.8.0-49.49..Ubuntu-6.8.0-50.51 tags
(if indeed that is the range).
