Good morning Tim Today (Sunday 17 April), I reproduced the boot difficulty and this is what happened:- gdm3 did not reach the graphical log in (greeter) - as I reported via launchpad on 16 April.
The last line of the wall of text was "[ OK ] Started Gnome Display Manager............and deal with any system changes" The PC stopped there and after approx 3-4 minutes, I managed to open a terminal with Ctrl Alt F2 and successfully changed from gdm3 to Lightdm. Subsequent reboot with Lightdm was OK. Yesterday, I was unable to fix this via the grub menu Recovery - today I remembered the Ctrl Alt F2 path to a terminal. To be honest, I have had so few problems with Ubuntu and Gnome 2 and 3 since 2007 that my repair skills are very rusty. My hardware is approx 5 years old as follows:- Intel Q45/Q43 graphicsPentium Dual Core CPU E5400Intel motherboard DQ45EK Report attached as requested. I hope it is helpful.

I added gnome-shell but still used lightdm to log in. Lightdm works OK with both gnome-shell and unity. I changed the greeter to gdm3 (sudo dpkg-reconfigure lightdm) and the subsequent log in provided a wall of text and stopped booting. I could not get to a terminal to reconfigure the greeter and I had to switch off the PC via the power button. I was unable to change the log-in greeter using the Ubuntu recovery system. Following an internet search, I added an instruction to the grub entry to allow me to boot directly into a bash command shell to reconfigure and reboot with lightdm. Instruction is:- "add the following to the end of the line starting with /boot/vmlinuz… –add rw init=/bin/bash" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1571227/+subscriptions -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1571227 Title: Unable to arrive at Desktop using gdm3 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1571227/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
