I have installed latest nVidia graphic driver via this PPA xorg-edgers/ppa. Now in Nvidia X server setting showing the driver version is 346.35. But in Ubuntu's Additional Drivers there is no such driver rather it marks the Nouveau driver. I ran lspci -vnn | grep -i VGA -A 12.01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GF104 [GeForce GTX 460] [10de:0e22] (rev a1) (prog-if 00 [VGA controller])Subsystem: Gigabyte Technology Co., Ltd Device [1458:34fc]Flags: bus master, fast devsel, latency 0, IRQ 53Memory at fc000000 (32-bit, non-prefetchable) [size=32M]Memory at d8000000 (64-bit, prefetchable) [size=128M]Memory at d4000000 (64-bit, prefetchable) [size=64M]I/O ports at b800 [size=128][virtual] Expansion ROM at fe780000 [disabled] [size=512K]Capabilities: <access denied>Kernel driver in use: nvidia01:00.1 Audio device [0403]: NVIDIA Corporation GF104 High Definition Audio     Controller [10de:0beb] (rev a1)Subsystem: Gigabyte Technology Co., Ltd Device [1458:34fc]Which version of graphic driver I am using currently ? If I am not using nVidia's driver then how can I use nVidia's driver. I am running Ubuntu 14.04 64bit OS.
What is the GPU driver I am currently running?
ubuntu;drivers;nvidia;gpu
First of all: There are no drivers under Linux.  There is something called modules which serves the same purpose and as some large company in Redmond, WA calls those drivers, some people call it that too under Linux...  ;-)Typing nvidia-settings --version will tell you what version of the NVidia module is currently installed (even when it's not running).lsmod | grep video will show you the running video module.modinfo szWhateverWasTheOutputOfThePreviousCommand will give you the version of the running module.
