Describe the Bug

When attempting to debug a system issue, it's not uncommon to encounter cryptic error messages in the system log. One such error that can be particularly puzzling is the VK_ERROR_INCOMPATIBLE_DRIVER complaint. This error is often associated with the Vulkan graphics API, which is used by various applications, including Chromium. In this article, we'll delve into the details of this error, explore the possible causes, and provide a step-by-step guide to resolving the issue.

Symptoms of the Bug

The VK_ERROR_INCOMPATIBLE_DRIVER error is typically accompanied by a warning message indicating that no drivers were found. This can be seen in the system log, where the Chromium process is complaining about the lack of drivers. The error message is usually preceded by a warning message indicating that the vkCreateInstance function failed.

Example System Log Output

Mar 12 09:44:17 hoarder chromium[644]: Warning: vkCreateInstance: Found no drivers!
Mar 12 09:44:17 hoarder chromium[644]: Warning: vkCreateInstance failed with VK_ERROR_INCOMPATIBLE_DRIVER
Mar 12 09:44:17 hoarder chromium[644]:     at CheckVkSuccessImpl (../../third_party/dawn/src/dawn/native/vulkan/VulkanError.cpp:106)
Mar 12 09:44:17 hoarder chromium[133]: [133:133:0312/094417.584647:ERROR:service_client.cc(36)] Unexpected on_device_model service disconnect: The device's GPU is not supported.

Steps to Reproduce

To reproduce the issue, follow these steps:

Start the hoarder instance: Begin by starting the hoarder instance on your Proxmox server.
Wait: Allow the instance to start and stabilize.
Run journalctl -f: Open a terminal and run the journalctl -f command to view the system log in real-time.
Observe the error: As the Chromium process starts, observe the system log for the VK_ERROR_INCOMPATIBLE_DRIVER error.

Expected Behaviour

In an ideal scenario, the Chromium process should start without any errors, and the system log should remain quiet. However, in this case, the presence of the VK_ERROR_INCOMPATIBLE_DRIVER error indicates that something is amiss.

Possible Causes

The VK_ERROR_INCOMPATIBLE_DRIVER error can be caused by a variety of factors, including:

Incompatible graphics drivers: The error message suggests that the graphics drivers are incompatible with the Vulkan API.
Missing or corrupted graphics drivers: It's possible that the graphics drivers are missing or corrupted, leading to the error.
Conflicting system configurations: Conflicting system configurations, such as multiple graphics drivers installed, can cause the error.

Troubleshooting Steps

To resolve the VK_ERROR_INCOMPATIBLE_DRIVER error, follow these troubleshooting steps:

Step 1: Verify Graphics Drivers

Verify that the graphics drivers are installed and up-to-date. You can do this by running the following command:

sudo apt-get update
sudo apt-get install -y nvidia-driver

Replace nvidia-driver with the actual graphics driver package installed on your system.

Step 2: Check System Configurations

Check the system configurations to ensure that there are no conflicting settings. You can do this by running the following command:

sudo lshw -c video

This command will display the system's video configuration, including the graphics driver and any other relevant settings.

Step 3: Reinstall Graphics Drivers

If the graphics drivers are missing or corrupted, reinstall them using the following command:

sudo apt-get install -y --reinstall nvidia-driver

Replace nvidia-driver with the actual graphics driver package installed on your system.

Step 4: Update System Packages

Update the system packages to ensure that all dependencies are up-to-date. You can do this by running the following command:

sudo apt-get update
sudo apt-get upgrade -y

Step 5: Reboot System

Reboot the system to ensure that the changes take effect. You can do this by running the following command:

sudo reboot
