How do I use an activated(but not in use) driver? [duplicate]

Solution 1:

There is bugs reports for this issue at launchpad: jockey/+bug/771788 e nvidia-graphics-drivers-173/+bug/772207. Add your card details then mark it to report that you have the issue. Hopefully, it will be fixed soon!

Solution 2:

I have had problems with my nvidia card as well, and I think my answer to a similar question might help you. It list all my attempts (everything I found), plus what finally worked for me: adding nopat to the kernel parameters when booting. It is a known problem with nvidia cards.

For this case, what I hope should work is:

• use the 173 version of the nvidia driver
• force starting unity, by adding UNITY_FORCE_START=1 to /etc/environment

Solution 3:

It appears to be a bug at the app that checks for drivers update - jockey see this.

You can test if it is in use at least in three ways. Check the commands and the outputs following:

/usr/lib/nux/unity_support_test -p  

lspci | grep nVidia  

sudo lshw -C display

Reference.

Solution 4:

I have same configuration and exactly same message as you. But phrase "driver not currently in use" is false. Driver IS used. Check glxgears, if you have ~7800 fps, just relax.
