OK, in order to find the culprit I completely removed the file /etc/X11/xorg.conf Then logged out. I noticed that the "options" on the lower part of the screen were now visible again. Logged back in, and used this to get a basic xorg.conf: sudo dpkg-reconfigure -phigh xserver-xorg I added in the Section "Device" this line: Driver "nvidia" I logged out and the options were still there. As a person helped me through this, they said it's probably the xorg.conf that was breaking the display.
I did not use "screens and graphics" to change my display resolution, but I used: gksu nvidia-settings Logged out and everything was still ok. Seems the problem appears when I try to configure my resolution with the displayconfig-gtk application. I have attached both xorg.conf: a) generated by screens and graphics / displayconfig-gtk (not working) b) generated by nvidia-settings (working) ** Attachment added: "xorg_conf.zip" http://launchpadlibrarian.net/13540880/xorg_conf.zip ** Also affects: displayconfig-gtk (Ubuntu) Importance: Undecided Status: New -- Screen resolution problems at login screen https://bugs.launchpad.net/bugs/150938 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
