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 Touch seeded packages, which is subscribed to upstart in Ubuntu. https://bugs.launchpad.net/bugs/1369216 Title: gpu-manager: /etc/modprobe.d is not a file Status in “upstart” package in Ubuntu: Confirmed Bug description: Get these lines logged into gpu-manager.log, on that fresh stock installation /etc/modprobe.d is not a file update-alternatives: error: no alternatives for x86_64-linux-gnu_gfxcore_conf ProblemType: Bug DistroRelease: Ubuntu 14.10 Package: upstart 1.13.2-0ubuntu1 ProcVersionSignature: Ubuntu 3.16.0-14.20-generic 3.16.2 Uname: Linux 3.16.0-14-generic x86_64 NonfreeKernelModules: nvidia ApportVersion: 2.14.7-0ubuntu2 Architecture: amd64 CurrentDesktop: GNOME Date: Sun Sep 14 08:42:45 2014 ProcKernelCmdline: BOOT_IMAGE=/boot/vmlinuz-3.16.0-14-generic root=UUID=7c755ed6-51cc-4b75-88ac-9c75acf82749 ro SourcePackage: upstart UpgradeStatus: No upgrade log present (probably fresh install) UpstartBugCategory: System UpstartRunningSessionVersion: upstart 1.13.2 UpstartRunningSystemVersion: init (upstart 1.13.2) modified.conffile..etc.default.whoopsie: [modified] modified.conffile..etc.gdm.Init.Default: [modified] mtime.conffile..etc.default.whoopsie: 2014-08-29T19:12:47.435075 mtime.conffile..etc.gdm.Init.Default: 2014-09-07T17:01:23.246055 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/upstart/+bug/1369216/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
