I have been running 14.1 Cinn for maybe two weeks, and suddenly it won't boot, only go to blank screen. I can get to grub menu and followed the directions in viewtopic.php?f=46&t=122257
However, after editing and pressing F10, the machine booted to a blank screen,
Pressing Ctl + Alt + F1 gets me a simple login screen (tty). Login is successful.
sudo service mdm start
results in "Not starting MDM Display Manager; it is not the default display manager"
So what is my default DM, if not MDM??
Admittedly, I do not know what I am doing here, just following recipes......
I have a home built machine using Geforce GTX 550 TI, so that's nvidia.
I repeat: the machine ran great for two weeks: maybe something happen after the last running of Update Manager (???).
