The patch in the OP worked for me (12.04.01, x64) until two days ago; after performing a regular system update the slooow login returned. I tried the fix in post #48 in this thread; it worked once (after I rm both directories) but no more (even after I tried to rm the directories again). I went back to the ubuntuforms link in the OP and the fix in post #40 there works (for now): After lightdm comes on, switch to tty1 and 'sudo pkill accounts'. This survives logout (so far) but not restart/reboot.
I have sent along several logs in case this would help squash this veeery annoying bug. ** Attachment added: "lightdm.log" https://bugs.launchpad.net/ubuntu/+source/accountsservice/+bug/996791/+attachment/3518071/+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/996791 Title: Xubuntu 12.04 extremely slow login To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/accountsservice/+bug/996791/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
