NVidia drivers crash on Ubuntu 20.04

[dimitri-papadopoulos]

Hi,
I have a Dell Precision Tower 3620 with the following graphics card:
01:00.0 VGA compatible controller: NVIDIA Corporation GM107GL [Quadro K1200] (rev a2)
running Ubuntu 16.04, 18.04 and now 20.04 on this machine, always with the Nouveau driver until now. I want to switch to the proprietary NVidia and have attempted multiple times to install the suggested nvidia-driver-460 (and also nvidia-driver-390 just in case) using software-properties-gtk. The proprietary drivers install smoothly. Then I reboot, enter login/password at the gdm prompt, and get a black screen. From the system log:

Any clue? Any suggestion what I should be looking into?

The NVIDIA Corporation GM107GL [Quadro K1200] should work with the 460 series drivers, according to the manufacturer.
You need to disable Secure Boot in UEFI in order to use unsigned drivers.

[dimitri-papadopoulos]

Unfortunately disabling Secure Boot does not help. The error remains.

By the way, why should I disable Secure Boot in UEFI? I'm not certain that's what Chapter 4. Installing the NVIDIA Driver implies. Also, I would expect such an error to be caught much earlier and with a different error message.

[CelticWarrior]

So you have been installing the driver downloaded from Nvidia all along?
Very likely that IS your problem. ALWAYS install the driver already in the Ubuntu repository. And yes, disable Secure Boot.

What you should do now is uninstall *everything* that you installed from Nvidia and then reboot and open Additional Drivers. Select and apply. Reboot. And again, disable Secure Boot.

[dimitri-papadopoulos]

No, I haven't been installing the driver downloaded from Nvidia. I have been installing using software-properties-gtk. Secure Boot has been disabled but disabling it doesn't help.

[CelticWarrior]

If so, first of all, update UEFI.
Then run

sudo apt-get purge nvidia*

Reboot and install 460.

Is this a successively release upgraded system? If so better to do your backups and reinstall from scratch and this time make sure to select the option to install third-party drivers, firmware, etc. so the proper Nvidia drivers are installed automatically.

[dimitri-papadopoulos]

BIOS has always been up to date on this workstation. It used to be 2.16.2, and I have just updgraded to 2.17.1 to be on the safe side.

To fall back to the Nouveau driver after my unsuccessful attempts to install the NVidia proprietary drivers, I always run:

sudo apt purge nvidia-driver-460
sudo apt purge libnvidia-compute-460
sudo apt autopurge

This is a clean Ubuntu 20.04 installation, not an upgrade from a previous release. I have always reinstalled Ubuntu from scratch on my workstation (16.04, 18.04, 20.04).

Note that the Nouveau driver has its own issues (Nouveau driver freezes), so I am wondering whether this could ba a hardware problem. Any clue how I could investigate that?

After that failure I am still able to ssh into the machine. However, sudo reboot fails, I have to force a restart using the power button.

I eventually contacted Dell support and was sent a new GM107GL graphics card (under extended warranty). Double improvement:

• no more freezing with the Nouveau driver (fingers crossed),
• much less noise from the workstation (although I had cleaned the graphics card fan with compressed air).

I will test soon whether the Nvidia driver works any better with the new GM107GL graphics card. It looks like the previous GM107GL graphics card really had been defective from the start.

Once you do... Please run the UbuntuForum's system-info script in my signature line to gather hardware and system settings information so that we can see which kernel you are usong, which desktop, and a lot of other graphics related information, so we are not just guessing what those are.

I, even though I have supported the Linux Graphics Layer for years, and NVidia Graphics (among others) in Linux... Know that the current HWE Hardware Enablement Stack is having issues with the NVidia Drivers on some hardware combinations. One of my desktops was one of those. Just saying that outfront.

The above script also reports information if you have the HWE installed and what versions of... To diagnose that.
