Bug Description
$ lsb_release -rd
Description: Ubuntu Bionic Beaver (development branch)
Release: 18.04
$ apt-cache policy xorg
xorg:
Installed: 1:7.7+19ubuntu6
The system is an upgrade from 17.10 to 18.04. The X-server fails to start initially, on each boot. After switching to tty2 I can start the login daemon via
$ systemctl start sddm
and X and sddm work as expected. (i.e. X starts, the login daemon starts, I can login to an X session)
The system in question is a Lenovo X220 Thinkpad with integrated graphics. As lspci puts it:
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
This behaviour started as a result of the upgrade.

It seems to be an interaction with plymouth. Setting LINUX_DEFAULT= "quiet" ` i.e. removing the `splash` in /etc/default/grub and updating grub
`GRUB_CMDLINE_
$ sudo update-grub
works around the problem.
