I can confirm the same issue with my system, using an NVIDIA 660 GTX, running Mint 17 with Nvidia drivers 331.38. Turning off FXAA didn't work for me. None of the settings made a difference. The only thing worked was removing the NVIDIA settings file as suggested by xavier zinn. Now everything seems to be running flawlessly.

I tried various nvidia installs (nvidia-common, nvidia-prime, etc.) and when I would reboot I would get the lightdm screen to authenticate but the dash panel would not appear after logging in. Looking at .xsessions I noticed: init: at-spi2-registryd main process ended, respawning init: at-spi2-registryd respawning too fast, stopped My workaround has been: apt-get purge nvidia* and then to run NVIDIA-Linux-x86_64-331.49.run xrandr shows: Screen 0: minimum 8 x 8, current 3280 x 1080, maximum 16384 x 16384 LVDS-0 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 382mm x 215mm 1920x1080 60.0*+ 40.0 HDMI-0 connected 1360x768+1920+0 (normal left inverted right x axis y axis) 880mm x 506mm 1360x768 60.0*+ 1920x1080 59.9 60.1 60.0 1440x480 60.1 1280x768 59.9 1280x720 60.0 59.9 1024x768 60.0 800x600 60.3 720x480 59.9 60.1 640x480 59.9 59.9 DP-0 disconnected (normal left inverted right x axis y axis) DP-1 disconnected (normal left inverted right x axis y axis) DP-2 disconnected (normal left inverted right x axis y axis) Let me know if any other information would be helpful. I have seen that there are some nvidia related issues that will hopefully be worked out. I just wanted to document my experience in case others have a similar problem.
