I managed to reduce and almost eliminate the delay by removing the background image. Now the lightdm logfile reports a 3 second delay which I believe is acceptable. Maybe this bug has to do with the deallocation of the memory it allocated for the background image?
I also reproduced this behavior to my laptop that I just upgraded (12.04 -> 12.10). Strangely, although the laptop has a slow 4200rpm HDD instead of an SSD and a slower cpu, the mentioned lag is less than two seconds with the same settings... ** Attachment added: "lightdm.log" https://bugs.launchpad.net/lightdm/+bug/1069183/+attachment/3406807/+files/lightdm.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1069183 Title: LightDM KDE Greeter loads the desktop half a minute after login To manage notifications about this bug go to: https://bugs.launchpad.net/lightdm/+bug/1069183/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
