gridd-unlock-patcher

[!note] Credits This code is built by electricsheep49. The Windows replacement script is written by lcs.

Only Linux is supported for executing the patcher, see Releases.

The patcher supports both, Windows and Linux guests:

• For Windows guests, the GRID daemon is Display.Driver/nvxdapix.dll
• For Linux guests, execute which nvidia-gridd to find your GRID daemon. It's probably in /bin/.

How to patch

Prepare

1. Download latest release
2. Make executable chmod +x gridd-unlock-patcher
3. Download your FastAPI-DLS Root-CA from https://<your-dls-url>/-/config/root-certificate

Linux

This overwrites the given binary, make sure you have a backup!

1. Run patch gridd-unlock-patcher -g $(which nvidia-gridd) -c /path/to/my_root_certificate.pem
2. Restart nvidia-gridd service

Windows

This overwrites the given dll, make sure you have a backup!

1. Download windows-replace-nvxdapix.ps1 (written by lcs) to the Desktop of your Windows machine
2. Run Get-ChildItem -Path "C:\Windows\System32\DriverStore\FileRepository" -Recurse -Filter "nvxdapix.dll" -ErrorAction SilentlyContinue | Select-Object -First 1
3. Copy the nvxdapix.dll from the resulting path to your Linux host where the gridd-unlock-patcher is installed
4. Run patch gridd-unlock-patcher -g /path/to/nvxdapix.dll -c /path/to/my_root_certificate.pem
5. Copy the patched nvxdapix.dll back to the Desktop of your Windows machine
6. Run powershell.exe -executionpolicy bypass -file "$HOME\Desktop\gridd-apply-patch.ps1" as Administrator

Maybe one patched DLL per Driver-Release can be copied across all Windows machines matching the same Driver-Release!

Output should look like

PS C:\WINDOWS\system32> powershell.exe -executionpolicy bypass -file "$HOME\Desktop\gridd-apply-patch.ps1"
Searching for nvxdapix.dll in C:\Windows\System32\DriverStore\FileRepository...
