I was able to resolve this issue by removing intel grahics installer. Here are the steps I followed:
1) In additional drivers, select nouveau as default driver. 2) Purge nvidia using following command: sudo apt-get purge nvidia* 3) Completely remove intel graphics installer and files instaleld by it using following guide: http://theclonker.de/?p=89 replace quantal with trusty. 4) When you purge intel driver i915*, on next reboot an older version might get activated so remove it as well. Simply install synaptic and search "i915" and uninstall if any old version is activated. Restart after that. 5) Enable nvidia driver again in additional drivers. It should work fine! Now I am using xorg edgers repository and have installed nvidia 340.58 driver. It performs much better than nvidia 331 so I will highly recommend it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1369216 Title: gpu-manager: /etc/modprobe.d is not a file To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/upstart/+bug/1369216/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
