Public bug reported:
nvidia-driver-390 incorrectly recommended (and installed) as best driver
for NVIDIA GeForce GTX 1060 on a Dell G7 7588. This is leading to
segmentation fault while using glmark2 for example.
Series: Ubuntu 22.04.5 LTS
GPU: GeForce GTX 1060
Kernel: 5.15.0-186-generic
This is the version installed for ubuntu-drivers-common
```
dpkg-query -W -f='${Package}\t${Version}\t${Status}\n' ubuntu-drivers-common
ubuntu-drivers-common 1:0.9.6.2~0.22.04.11 install ok installed
```
ubuntu-drivers is listing *-390 as recommended and installed version

```
From the list of available ubuntu-driver devices, I was able to install *-580:
```
sudo apt-get purge nvidia-driver-390
sudo apt-get install nvidia-driver-580
sudo reboot
```
Which do not have the segmentation fault error, so not a kernel problem but a
problem on selecting the correct driver.
