Thank you very much Alberto for your prompt answer. Indeed, the problem was numlockx. It wasn't installed. And I don't want to install it, because the tune tip won't work, since I log in with a password, and I don't have a separate numeric keyboard, according to the 2.6th recommended action from this site. https://sites.google.com/site/easylinuxtipsproject/first
So, when I deleted that line at /etc/lightdm/lightdm.conf, the problem was PARTIALLY resolved, because the guests and root account log in, but my principal account still doesn't. In addition of that, the first blue image that shows after the grub neither appears in the nvidia-319 driver, but it does when I activate the X.Org X server driver, xserver-xorg-video-nouveau, so I would like to know why it occurs. Before it happened, I had to shut down my laptop by force (on/off button), because the shut down process had friezed, and it didn't shut down by itself. I suspect that there are several problems with X.Org... So I've tar'ed the /var/log/lightdm directory and /var/log/Xorg.0.log at the same tar. Is it necessary to reset my principal account? Is there something that I could do for repair it? Thank you very much for all. ** Attachment added: "/var/log/lightdm directory and /var/log/Xorg.0.log" https://bugs.launchpad.net/lightdm/+bug/873495/+attachment/3887372/+files/lightdm.tar.gz -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/873495 Title: LightDM fails to start after nvidia-current or nvidia-current-updates are installed (upstart job issue) To manage notifications about this bug go to: https://bugs.launchpad.net/lightdm/+bug/873495/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
