Nvidia driver question

[Guest]

I wanted to know what driver was being used I preceded to use the lspci -v command. What I saw confused me cause the driver on the Nvidia server settings is 435.21. than I look at the out out of the command above and it states

     Kernel driver in use: nvidia
    [B] Kernel modules: nvidiafb, nouveau, nvidia_drm, nvidia[/B]

How can it be still using the Nouveau driver and the 435.21? Am I reading this right? I had a big freeze up the other day with Firefox thats why I was looking at the GPU information.

The "Kernel modules" reports the installed kernel modules that can handle the device, not which modules are currently loaded, as it says on the previous line: "Kernel driver in use: nvidia"

You can check which modules are loaded with 'lsmod', 'lsmod | grep nvidia" should output the the nvidia modules and 'lsmod | grep nouveau' should output nothing (as the module is not loaded).

You're probably reading it wrong.

Kernel driver in use: nvidia

Kernel modules: nvidiafb, nouveau, nvidia_drm, nvidia means they're installed, not in use.

Try
inxi -G
That gives me:
drivers: nvidia (unloaded: modesetting,fbdev,vesa,nouveau)

Okay I was looking at the wrong line. I do not think the drivers could both load anyway not to think of it.

main@main-testing:~$ lsmod | grep nvidia
nvidia_uvm            876544  0
nvidia_drm             49152  9
nvidia_modeset       1122304  29 nvidia_drm
nvidia              19517440  1670 nvidia_uvm,nvidia_modeset
drm_kms_helper        180224  1 nvidia_drm
drm                   491520  12 drm_kms_helper,nvidia_drm
ipmi_msghandler       102400  2 ipmi_devintf,nvidia

What could cause the system to freeze up than? I was using Firefox with 4 tabs open and 4GB ram. does not seem to do that otherwise. Is the best driver for 1050it the 435 or its there a older version that support the same card?

I use some of the non-(Linux)traditional command line tools more often.

driver   : nvidia-driver-390 - third-party free recommended
driver   : nvidia-340 - third-party free
driver   : xserver-xorg-video-nouveau - distro free builtin

and then to see what's actually there

inxi -G
Graphics:  Card-1: Intel HD Graphics 530
          Card-2: NVIDIA GF108 [GeForce GT 730]
          Display Server: x11 (X.Org 1.20.5 ) drivers: modesetting,nvidia (unloaded: fbdev,vesa,nouveau)

          OpenGL: renderer: GeForce GT 730/PCIe/SSE2 version: 4.6.0 NVIDIA 390.132

These show the same info as lsmod, lspci, etc. But are better organized and a bit more concise.

This output suggests that the driver 435.xx already in use is the correct driver. But the same is stated on the driver manager. I am not used to an auto install of a NVIDIA driver that was new to me. normally I have to change from the Nouveau to the Non free.
