lightdm fails to start when the [SeatDefaults] section header is missing from /etc/lightdm/lightdm.conf.
Background... I have a setup script I use for all of my Ubuntu installs (https://github.com/convissor/ubuntu_laptop_installation). It's gotten many 12.04 going the way I like it, no problems. Part of what that script does is add some lines to /etc/lightdm/lightdm.conf. On 2014-01-24 I installed Ubuntu 14.04 on a new box for testing purposes. That went fine. Then I ran my setup script. Then I rebooted and wound up at a completely black screen. Every reboot, same thing. After some tracing what changed, I realized that the [SeatDefaults] section header is missing from the lightdm.conf file. So I added that line at the top of the conf, rebooted, and things ran normally. Took it out again to test, rebooted, got the same black screen. So either the version of lightdm that ships with 12.04 includes a lightdm.conf file with the header in it, or there's a bug in more recent lightdm versions that chokes on the incomplete lightdm.conf file my setup script creates. Note: when lightdm chokes, no lightdm log files are created, nor are there references to lightdm in any log files. This problem also exists in Ubuntu 13.10. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1164793 Title: Lightdm shows black screen during login To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1164793/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
