Graphical login failed

I just tried rebooting my machine and can't get a graphical login. It drops to a terminal just fine, but Sddm fails to start. Not sure what to check first; this box has not been rebooted in a week and I've taken upgrades as they've occurred. I'm running plasma-next with sddm. Graphics is ati Radeon hd4200. Using free Radeon driver. If someone can tell me what logs will be useful I'll post them.

Re: Graphical login failed

Immediately after dropping to TTY, run:

journalctl -xn

This reviews the last 10 journal entries with explanatory notes -- add a number to view more entries.

I think the Xorg.0.logs are in ~/.local/share/xorg these days

Re: Graphical login failed

Also please don't grep the Xorg log just for errors - the context really matters.  Check the Xorg logs and post them here if you need help interpreting them.

EDIT: actually if it's just the display manager failing to start, check the systemctl output.

Re: Graphical login failed

I just got home and made another stab at a reboot... and it worked. Two more reboots and it's still working fine. Very odd. I guess I'll post again if it gives me more trouble. Thanks for teh replies
