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 01-network- manager-all.yaml file as well proof enough? of some weird interactions between services now the minimal 01-network-manager-all.yaml on the new installs seems to be lacking something .. although the documentation says it should work .. which it does if your graphics start properly .. Wayland (ubuntu install) or amd/ati cards probably nvidia too I have not tested but if using the current default netplan and i915 as module NOT listed in /etc/modules .. it does not work it crashes and locks up and only a powerswitch shutdown works .. no reset button on laptop .. no console access is available either .. so it has taken a bit of time to determine all this .. Anybody know how to fix the netplan config in a "generic way" to cure this issue? the only problem is no control over switching networks .. NetworkManager does not seem to have control over the interface started by networkd .. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1821609 Title: lightdm login screen briefly appears and then blanks out on Intel(R) Core(TM)2 Duo CPU T5870 (crash in xorg before using "foreign grub") netplan mis-configuration maybe underlying cause.
