I have a laptop with a QHD+ screen (XPS 13 2015 9343) with Ubuntu 15.04 and kernel 4.1.3.
When I shut down the Ubuntu logo go to the top of the screen, the left of the screen then back to center. I have no problem at startup.
The problem is related to plymouth
so tried to run sudo update-alternatives --config default.plymouth
and changing the default options but none of them work.
How can I solve this ? Thanks in advance.
Installing kernel 4.1.4 fixed the issue.
(Consequently it is fixed in Ubuntu 15.10).
