Public bug reported:
I use Ubuntu 18.04.1 LTS on a Lenovo Thinkpad T460p.
Today I upgraded to Kernel 4.15.0-44 – since then my system crashes when
logging in (when the display resolution should switch). The previous
Kernel 4.15.0-43 works fine, though.
Here's the crash:

Bug description:
I use Ubuntu 18.04.1 LTS on a Lenovo Thinkpad T460p.
Today I upgraded to Kernel 4.15.0-44 – since then my system crashes
when logging in (when the display resolution should switch). The
previous Kernel 4.15.0-43 works fine, though.
