Sorry. I forget comment the line "Load Type1" in xorg.conf file that I attached.
And there are one more problem. X works well when I boot my laptop with nvidia 177 driver and the xorg.conf file. However if I try logout, the screen goes to problem. After long time later that I pushed logout button, the Nvidia log was appeared 3 times and X report that it can't detect drivers. So I have to reboot my laptop. This is driving me crazy. :-< -- Failed to load module "nvidia" https://bugs.launchpad.net/bugs/273801 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
