Hi Tim, you are right, the comment #24 file is from "gnome-shell --replace" under lxde. I tried to login directly to gnome-shell session from lightdm. That is unsuccessful. I can only see my mouse cursor. nothing else. everything is black screen except my mouse cursor.
First, the log file here is "gnome-session-gnome.log" instead of "gnome- session.log" Second, I am not sure how "gnome-session-gnome.log" works. Will every login create a new log file? or simply append to that log file? I did "cp gnome-session-gnome.log /somedir/" at the session I can not login gnome with nvidia driver by using VT. Then I login to gnome with intel driver successfully, when I check the updated log file, the first part of the file is the same. I am attaching both log files. One is at the time I failed to login gnome-shell with lightdm+nvidia. Another one is at the time I login gnome-shell successfully with gdm+intel. Thanks. ** Attachment added: "gnome-session-gnome.log" https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1288572/+attachment/4017627/+files/gnome-session-gnome.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1288572 Title: Nvidia driver does not work in Ubuntu GNOME trusty "14.04" (Optimus laptop) To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-shell/+bug/1288572/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
