Login Loop after installing 390.25 on Ubuntu 18.04

Graphics / Linux Linux
1

I have a Titan V and have installed the driver nvidia-390.25 on Ubuntu 18.04.
I use nvidia-smi can show the information of Titan V. However, when I use nvidia-xconfig and reboot, the login Loop appears. I can not solve it.
Here is the URL of my bug report.

Don’t use the .run installer, please remove the driver using the --uninstall option, then use the ubuntu graphics ppa to install the latest driver.

I have tried.

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update

But it showed me like that.

Is it the problem that the Titan V is new and there is no driver support on Ubuntu?
Or the problem of Ubuntu.

There are two kinds of graphics cards in the server, integrated graphics card and Titan V. I want to use Titan V to display. So I typed the command nvidia-xconfig and reboot. However, the login loop appear.

The Titan V is well supported.
The errors you’re seeing are from the bumblebee ppa, unrelated. In case you installed bumblebee, uninstall it.
Install the driver:
sudo apt install nvidia-driver-410

See if you can disable the integrated gpu in bios.

Yeah, it worked. But I can not open the nvidia-settings to use the Titan V.
It showed that.

ERROR: Unable to load info from any available system

nvidia-smi can show the information of the GPU. But nvidia-settings can not work.

nvidia-xconfig show that.

good@AirSim:~$ sudo nvidia-xconfig
[sudo] password for good:
