Nvidia driver updated, activated but not in use [SOLVED]

[amintuser]

Mint 13.
After recent update, I can see in jockey-gtk that latest nvidia "331 updates" driver activated but not in use.

Code: Select all

lspci -k | grep VGA -A2
01:00.0 VGA compatible controller: NVIDIA Corporation GK106 [GeForce GTX 650 Ti] (rev a1)
	Kernel driver in use: nvidia

I would remove the driver and re-install whatever is the correct nVidia driver for your machine. It looks to me as if the last nVidia update failed.

Did your rebooted the system after installation? If not, please do so.
After reboot, can you run the following terminal command and paste the output here:

Code: Select all

inxi -Gxz

Code: Select all

inxi -Gxz

It is correctly installed. When you go to the additional Driver menu, does is still it's not in use?

Yep. The same. Still is not in use.

I did rebooted after driver update in the beginning. And I saw that 331-updates was not in use. Then I decided to switch (via jockey) to open-source driver and to get back to 331-updates after. So, I've chosen nouveau. Then rebooted. On that moment I saw that open-source nvidia driver has disappeared as an option in jockey. I deleted 331-updates (which was still active but not in use). And after that I installed 331-updates again. Rebooted. Result is on the picture above (same as before).

In a terminal run this command:

Code: Select all

sudo nvidia-xconfig

Then reboot and check the Additional Driver menu again if the driver is in use or not.

[amintuser]

sudo nvidia-xconfig (before reboot)

Code: Select all

Using X configuration file: "/etc/X11/xorg.conf".

VALIDATION ERROR: Data incomplete in file /etc/X11/xorg.conf.

sudo nvidia-xconfig (after reboot)

but driver is still activated but not in use after reboot.

Did you reboot and checked the additional driver menu if the driver is in use now?

[amintuser]

the same

This appears to be a problem with Jockey/Additional Drivers in LM13 reporting driver not in use, when, in actual fact, they are installed and functioning correctly.
You have direct rendering enabled so I assume you're OK.
If everything is working as expected you should just ignore it.

[amintuser]

yep, looks like Jockey/Additional Drivers bug.

[nomko]

but driver is still activated but not in use after reboot.

As long the output of the inxi -Gxz command doesn't give any faults, the driver is in use.

[amintuser]

today, jockey updated, and now everything shows correctly. Driver activated and is in use.
