In Additional Drivers under Software & Updates, the NVIDIA driver is stuck on Continue using a manually installed driver, and all other options are greyed out.

I want to set the driver to proprietary driver(nvidia-driver-390), which was originally selected before I changed it to the open source driver, but now it is stuck.

How can I resolve this issue? Should remove all NVIDIA drivers and install them again? If so , how to do it safely in Ubuntu 20.04?

Additional info:

1. cat /var/log/Xorg.0.log output:

2. lspci -k | grep -EA3 'VGA|3D|Display' output:

This problem should be fixed by running

sudo ubuntu-drivers install

after a reboot.

I encountered myself in a similar situation because of broken packages (Ubuntu complained on launching sudo ubuntu-drivers autoinstall; further in Software & Updates -> Additional Drivers my Nvidia graphics was locked to manual installation). I solved it like this:

1. Remove all nvidia packages and make sure nouveau is installed (you need sudo rights):

dpkg -P $(dpkg -l | grep nvidia-driver | awk '{print $2}')
apt autoremove
apt install xserver-xorg-video-nouveau

2. Reboot
3. Reinstall latest nvidia packages (again, sudo rights):

ubuntu-drivers autoinstall

Here is my solution for the mouse lag situation. open NVIDIA Settings.

$ nivdia-settings

select this -> PRIME Profiles - NVIDIA (Performance Mode)

after reboot, your mouse or the animation of Ubuntu is as smooth as it used to be.

I also couldn't update to a newer Nvidia driver because a manual driver was installed, in my case from 470 to 510 driver on an Focal Desktop system of Canonical.

My solution was:

1. Open a terminal and run the command:

   sudo ubuntu-drivers autoinstall

   The above will install the newest recommended driver.

2. Wait until all automatic commands are executed and reboot the system.

3. The Linux kernel loaded the 510 driver.

4. Checked Additional Drivers in Software & Updates, which points to Nvidia 510 driver.

The accidentally selected manual driver option was removed.

My issue is that I able to select the NVIDIA driver and after I reboot the computer I checked the info still dont detect the external GPU.
