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 files to give exclusive control to NetworkManager ..run netplan apply as long as I don't reboot I can use NetworkManager as per normal
As soon as I try to reboot back into the install (via and foreign grub as defined above) I get exactly the same crash pattern as before .. so the deduction is that netplan configuration problems are causing the plymouth/xorg issues when you use only NetworkManager as a renderer .. so I am altering the title here again ** Summary changed: - 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") + 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. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in 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.
