In this forum http://forums.nvidia.com/index.php?showtopic=167422 I found some information that fix the problem, basic steps are:
1) Download the correct driver from nvidia web page (I couldn't get it fixed with Ubuntu driver at any way) 2)Purge nvidia packages: sudo apt-get purge nvidia-* 3) Create the file "/etc/modprobe.d/nvidia-graphics-drivers.conf" with the following contents: blacklist vga16fb blacklist nouveau blacklist lbm-nouveau blacklist nvidia-173 blacklist nvidia-96 blacklist nvidia-current blacklist nvidiafb 4)create or adjust the /etx/X11/xorg.conf file to: Section "Device" Identifier "Device0" Driver "nvidia" VendorName "NVIDIA Corporation" EndSection 5) reboot (You can also unload nvidia modulos and the others that I put in blacklist with command "modprobe -r module", example: modprobe -r nouveau 6) If you restarted it will tell you that it can't start X ( low graphics mode ) , then choose a text based console login (if it does start in X, just press ctrl-F1, log yourself in and call "sudo service gdm stop" or "sudo stop gdm" 7) run the nvidia installer and when it asks to run nvidia-x-config, answer yes To run the nvidia installer, you should go to the folder with driver (ej: cd Downloads). Change the installer permissions to be executable (chmod +x fileoftheinstaller.sh), execute the installer (sudo ./fileoftheinstaller.sh) 8) Restart, it should start xorg automatically -- gdm not starting on bootup with nvidia driver https://bugs.launchpad.net/bugs/573455 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
