I used the manual way to debug why gdm doesn't show the login screen (inferring that it's because gnome-shell is not running). I "inferred" it initially by looking at the mouse cursor blinking. Before, when the login screen shows up, the mouse would blink once then the login screen shows up. Now the mouse would blink once then just blink again instead of showing the logins screen. I can also see the output of ps -AfH, wherein it shows that gnome-shell isn't running even when gdm-x-session is running under the gdm user. I still don't know why there's no crash file though. Any pointers on how to debug this?
Thank you for your help.
