The proprietary NVidia drivers for the GeForce GTX 750 are acting up again. Here’s the fix:<\/p>\n
First verify that the wrong driver is in use:<\/p>\n

Download the NVidia 64-bit Linux driver.\u00c2\u00a0 At the time of this writing, it’s at\u00c2\u00a0https:\/\/www.geforce.com\/drivers\/results\/145182<\/a><\/p>\n
Install the driver. This is a two step process because the Nouveau driver is likely loaded by initramfs and needs to be removed. This requires a reboot.<\/p>\n
sudo service lightdm stop\r\nsudo sh .\/NVIDIA*\u00c2\u00a0 # This is the driver you just downloaded\r\nsudo update-initramfs -u\u00c2\u00a0 # purge nouveau driver from initramfs\r\nsudo reboot<\/pre>\nIf your graphics are running at the right resolution, you can stop here.\u00c2\u00a0 If not, continue:<\/p>\n
sudo service lightdm stop\r\nsudo sh .\/NVIDIA*\r\nsudo service lightdm start<\/pre>\n
