Okay, this bug has absolutely nothing to do with grub or netplan.
Changing the renderer couldn't possibly affect the behavior of X, and
the grub configuration looks, at a glace, to be run-of-the mill; pretty
much default if you disregard that there is any number of different
installs on the
bug is still present in disco xubuntu iso "final" 04-13.1-2019

Title:
lightdm login screen briefly appears and then blanks out on Intel(R)
okay a previous "fresh install that was crashing plymouth
screen/lightdm/xorg was fixed by copying a known working set of netplan
conf files into /etc/netplan ..
the 01-netcfg.yaml from the "network install" uses networkd as the
renderer .. with a working network device config.. plus the
okay I stumbled across something .. the network install .. used netplan
to set-up my wifi connection to start on boot .. so as soon as systemd
networkd starts wifi is started NetworkManager thus has no access or
anyway to try for other networks.. so I tried to change this.. If I edit
the config
An additional data point for reference .. did a netboot install of
xubuntu using "daily" amd64 netboot mini.iso .. base install followed
by taskselect install of xubuntu ..
boots normally plymouth and lightdm screens appear as expected .. also
switching to foreign grub .. it still boots
okay apr 8 and apr 9 iso's have same issues kept logs of various boots
into the fresh installs .. no change in grub-source during testing was
made .. all with fresh installs
typical first boot is normal .. no crash of xorg on first start ..
second boot shows lightdm briefly then xorg crashes
third boot of same install ..
** Attachment added: "third reboot of fresh install xorg.0.log.old --
slighjtly different"
