Hi, For the last few months, every time I installed an NVIDIA driver update my display manager won't come up afterwards (meaning after having rebootet the system). Having had this issue for a few times no I have however come up with a reliable workaround, running `systemctl restart display-manager`. Afterwards X will start reliable after reboots. But, only if I did the explicit restart one. Just doing another reboot won't fix it. Is anybody else observing this? Weirdly I actually have to restart the display manger as it claims to be running despite the journal telling that X died during startup. I have attached the journal for the display-manager unit showing the initial start and the successful start when I requested the restart.
