Hello everyone,
I'm encountering a similar issue as @ernest. After successfully encrypting /home/phablet with LUKS, my screen remains black after restarting LightDM, although SSH access continues to work fine. This happens on my Redmi Note 9S Pro running Ubuntu Touch 20.04 OT-5.
The workaround of locking the screen (using the power button) before initiating the force-reload of LightDM doesn't seem to work reliably anymore. I suspect that something has changed in OT-5, causing LightDM not to come back correctly when it's restarted while the display is on.
Has anyone experienced similar issues with OT-5 or knows of a more reliable way to restart LightDM without the screen staying black? Any help or tips would be greatly appreciated!
Thanks in advance!
