Thank you for taking the time to report this bug and helping to make Ubuntu better. It sounds like some part of the system has crashed. To help us find the cause of the crash please follow these steps:
1. Look in /var/crash for crash files and if found run: ubuntu-bug YOURFILE.crash Then tell us the ID of the newly-created bug. 2. If step 1 failed then look at https://errors.ubuntu.com/user/ID where ID is the content of file /var/lib/whoopsie/whoopsie-id on the machine. Do you find any links to recent problems on that page? If so then please send the links to us. 3. If step 2 also failed then apply the workaround from bug 994921, reboot, reproduce the crash, and retry step 1. Please take care to avoid attaching .crash files to bugs as we are unable to process them as file attachments. It would also be a security risk for yourself. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1856846 Title: Gnome Xorg sessions fail to start with LDAP users (but Wayland or local users work) Status in xorg-server package in Ubuntu: Incomplete Bug description: When trying to login to Gnome with an remote user from an LDAP (LDAP is available and connectable when in GDM) using X11, GDM loops around three to five times before actually granting access to the desktop.
