[Solved] Recent update - Can't login: Screen flashes

Last night I ran pacman -Syyu and did a reboot. Now I can’t seem to login. It appears as if lightdm won’t load. My screen just cycles between a black screen and a terminal login prompt. I was able to login using single user mode and pull some log files. Maybe, someone can help because honestly I don’t even know where to start.

Re: [Solved] Recent update - Can't login: Screen flashes

Welcome to the Arch Linux forums.
If you boot normally, can you get to a console using Ctrl-Alt-F2 (or F3, F4, ...).  It might be that when you try this, you will get sucked back into tty1 when lightdm restarts.
If it does work, log in and use systemctl to stop lightdm.   Otherwise, you can boot into single user mode and disable lightdm.    Then you might try updating again, just in case you caught a server update in process.  You might try reinstalling mesa-libgl

Thanks for the help.

I was able to disable lightdm in single user mode. From there I tried startx but it would exit almost immediately. I figured it might be something with the nvidia driver. I found the following:

I appended the following to the kernel line in /boot/grub/grub.cfg:

video=vesa:off vga=normal

This fixed my issue.
