[SOLVED] unable to start x session from lightdm login screen

Howdy,

I've looked around quite a bit, but unable to debug this issue so far!

The strange part is that I was doing only some minor tweaking when X seems to have stopped working with the lightdm login screen. I added a file

/usr/share/X11/xorg.conf.d/50-thinkpad-x230-touchpad.conf

, moved to another TTY (alt + ctrl + F1) and ran

startx

to test the changes to my pointer configuration. It worked well as I was adjusting and debugging the pointer speed, getting a smoother result. As I was trying to restart or end the X sessions I started on a couple different TTY's, at some point I ran a command like

pgrep X | sudo xargs kill

, assuming that I'd kill the X11 processes, which I could restart and therefore see an updated pointer movement in the default TTY7.

Unfortunately, this didn't work, and I rebooted the computer. After loading fresh, I landed on the lightdm login screen. However, when I enter my correct username and password, the lightdm login screen goes black for a second, then returns, without loading my desktop environment

I am able to enter another TTY, login at the terminal, then run

startx

, but this is a huge bummer! Especially confusing is that I removed this configuration file (described above) for my pointer, so I don't understand what is persistent across reboots that is causing this problem! Perhaps lightdm or x or some other program created a file that I need to modify, delete, or reinstall?

Doing some forensics, not finding any alarming or related error messages. Let me know if I should post any specific kinds of logs that might help in resolving this issue.

I'm very inexperienced with X and all, so I get the impression that if I'm able to learn a bit more about how lightdm starts my x session, I should get closer to resolving this issue.

Thanks for any help!

Oooo! I solved it 8)

For some reason, I lost ownership of my ~/.Xauthority file, probably because it was regenerated for root when I killed X11 with sudo -- oops

If you could edit the title of your first post and add [SOLVED]?

If there are no "Oooops!", then you aren't tweaking hard enough

EDIT: ninja'd!
