Hello, I'm going to ask you to upload some log files to help diagnose this bug. Please reinstall lxdm 0.4.0 and reboot into it, triggering the bug. Then downgrade back to 0.3.0 (or however you recover the system) and copy some log files to your home directory using the following commands:
cat /var/log/Xorg.0.log > Xorg.0.log.txt cat /var/log/Xorg.0.log.old > Xorg.0.log.old.txt cat /var/log/kern.log > kern.log.txt sudo cat /var/log/lxdm.log > lxdm.log.txt sudo cat /var/log/lxdm.log.old > lxdm.log.old.txt lspci -vvnn > lspci.txt cat /etc/lxdm/default.conf > default.conf.txt Then upload all of these files to this bug report. (Their names are the string after ">" in the above commands.) ** Changed in: lxdm (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/823621 Title: Black screen at login To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxdm/+bug/823621/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
