Need restart lightdm at every startup - console login screen

Question

Everytime I boot up my ubuntu 12.10, I get a black console screen.

I need to login in tty, and restart lightdm : sudo service lightdm restart

Then the GUI lightdm login screen appears as expected.

How to solve this annoying problem ?

Thank you.

Solution 1

This issue could be related to the use of a SSD.

If the first solution doesn't work for you, another workaround is to delay the startup of lightdm.

sudo nano /etc/init/lightdm.conf

and just BEFORE exec lightm, insert this single line :

sleep 2

Adjust the time (in seconds) depending on your needs (2 sec works for me). Save the file, and restart !

Found this solution here : http://www.webupd8.org/2013/01/ubuntu-lightdm-black-screen-when-using.html

Solution 2

Finally, I solved the problem by :

• installing GDM: sudo apt-get install gdm
• choosing it by default: When asked, choose GDM as your default X windows manager
• restarting: sudo reboot
• Reverting to lightdm as default X window manager: dpkg-reconfigure lightdm

Ps : firing the command dpkg-reconfigure lightdm without having installed GDM before didn't solve my problem. So try installing GDM before.

My kernel is 3.5.0-19-generic and my architecture 64bits. So I don't think i encountered this bug...anyway, I found a way to solve that annoying problem. Thank you.

same issue exists on 32-bit. i don't know how i got to this state, though. i had both gdm and lightdm before i tried your fix (changing to gdm and back to lightdm).

oups, you're right. the command is sleep, and not delay. Updated ! thx
