sometimes ubuntu login screen does not show after boot

Asked by peterK

sometimes ubuntu login screen does not boot up, only a promt "_" is blinking.
I have a 64bit Ubuntu 13.04 and single boot (no dual boot with windows)

When in this blinking mode I type:
    ctrl+alt+F1
Then login and type
    #startx
and get the below error in the log file /var/log/Xorg.1.log
then I type
    # sudo service lightdm restart
and everything starts up nicely again with the correct login screen.

if you run:

gksudo gedit /etc/rc.local

add the line:

service lightdm restart

above the 'exit 0' line, save the new file and close gedit. Is it ok?

Thank you for the answer!
The problem with this workaround is that I have to login twice. I get the login screen two times before entering the ubuntu desktop.

Thank you for the answer!

It works when I get the fault with the login screen that does not show after boot.

But this does not happen all the time (only sometimes).

So on working reboots, I have to login twice. I get the login screen two times before entering the ubuntu desktop.

Could this be solved in another way?

If you want a workaround as @actionparsnip suggested, then I think the most best would be something like below (same order).

    service lightdm stop
    sleep 3
    service lightdm start

Above lines will stop and start lightdm within 3 seconds , no matter if the fault appears or not. So you will not have to login twice.. The only problem (if is a problem) here is the delay time of 3 seconds in boot.

Thank you for the answer!

This workaround still gave the same symptom, I had to login twice.

First the login screen appears, I log in, then I see a text saying something like "lightdm stopped/waiting" then the login screen appears again.

Is it only my machine that gives this behavior?

Maybe the script could be put somewhere else, to be executed earlier, not after my first login?

This might be an occurence of bug #1163404

You could check if reverting to xserver-xorg-core 2:1.13.3-0ubuntu2b1 helps

I have found an acceptable workaround until this is fixed.

Acceptable workaround:
lightdm login screen --- login as a user --- press power button --- select "shutdown"
this has worked 20 out of 20 times, no problem with startup screen.

I have found ways to recreate the problem:

Problem recreation 1:
lightdm login screen --- login as a user --- press power button --- select "restart"
worked 8 out of 10 times
2 times gave a dark screen with hardly visible login screen.

Problem recreation 2:
lightdm login screen --- select "restart"
worked 7 out of 10 times
3 times gave a dark screen with hardly visible login screen.

Problem recreation 3:
lightdm login screen --- select "shutdown"
worked 8 out of 10 times
1 time gave a dark screen with hardly visible login screen.
1 time gave not started lightdm login screeen. which can be restarted with ctrl+alt+f1, "sudo servie lightdm restart" as described at the beginning of this question.
