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.

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.

Update typing:

nvidia-smi

gives you the driver verson nowadays.

Old answer:

Typing nvidia-settings --version will tell you what version of the NVidia driver 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.

  • thanks for the reply. but lsmod | grep video does not show anything. @Fabby – Muztaba Hasanat Feb 15 '15 at 13:28
  • Try copy-pasting the command because unless you're running a server that has no GUI, it should output something (actually a few lines). BTW, the xorg.edgers is an "open-source" x server repackaging of the NVidia proprietary drivers, so it shows up like "nouveau" under the GUI anyway... so you should be fine in all cases (just double-verified) – Fabby Feb 15 '15 at 14:37

    The linux kernel has modules, but Xorg has drivers. – fwyzard Jun 29 '18 at 7:19
  • Updated. Not as funny as before now however, but indeed more correct. @fwyzard – Fabby Jun 29 '18 at 9:24

If using prime-select (nVidia Optimus) on Ubuntu 18.04 (Dell XPS 15 9570) then use:

prime-select query

and it responds with intel or nvidia, depending on what you chose last.
