Public bug reported:
I recently installed Ubuntu 20.04 (20200402) with LVM encryption and automatic
logon.
So I enter my encryption password and after the motherboards boot logo it will
login automatically to desktop. I also chose the additional drivers and so
nvidia-driver-440.
Everything seems to be OK until I select a scaling above 100% (e.g. 200%) in
settings. Next reboot, I enter my encryption password. When the automatic logon
process should happen, the monitor turns off and says that no display signal is
available.
Currently I was able to return to a working setup by pressing CTRL + ALT + F4,
login and enter the following commands to remove nvidia-driver and use XORG
instead:
sudo apt purge nvidia-driver-440
sudo apt autoremove
sudo reboot
I am pretty sure that the issue will occur again, if I choose NVIDIA
driver again.
Any thoughts?
EDIT: On Ubuntu 19.04 I had a similar bug: If I started my PC and the
monitor was not turned on, the monitor reported no signal available
after turning it on. I was not able to see the boot-up field to enter my
encryption password. Unfortunately I didn't test, if I were able to
enter my password and logon anyway. Workaround was to turn the monitor
on, before starting the PC.
