Troubleshooting

Integrated GPU​

Some notebooks and desktops have both an integrated and discrete GPU, where the integrated might be preferred by the operating system for energy saving reasons.

Gestaltor requires OpenGL 4.1, which might not be supported by the integrated GPU, therefore we reccomend setting the default graphics card for Gestaltor.

This can be done from NVIDIA Control Panel or AMD Radeon Software or by setting the preferred GPU for the application in Windows settings.

Gestaltor Crashing immediately after start​

Gestaltor needs to perform some GPU-heavy calculations at the start which can trigger "Timeout detection and recovery" (TDR) in Windows. Unfortunately, we can not prevent this from happening, but you can increase the TDR delay in the Windows registry.

Solution: Set both "TdrDelay" and "TdrDdiDelay" to a higher value in the registry, e.g. 30 seconds.

  1. Open the Windows registry editor as an administrator
  2. Navigate to GraphicsDrivers in the left pane of the editor by expanding the folders: Computer > HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Control > GraphicsDrivers
  3. Add a new DWORD (32-bit) value by right-clicking on the right pane and selecting New > DWORD (32-bit) Value
    • Name the new value TdrDelay
  4. Double-click on the value of TdrDelay and set the value data to the desired delay in seconds (e.g. 30)
    • Be sure to select the Decimal base
  5. Add another new DWORD (32-bit) value by right-clicking on the right pane and selecting New > DWORD (32-bit) Value
    • Name the new value TdrDdiDelay
  6. Double-click on the value of TdrDdiDelay and set the value data to the desired delay in seconds (e.g. 30)
    • Be sure to select the Decimal base
  7. Make sure the values are set correctly by checking the data column in the right pane
  8. Close the registry editor and restart your computer

See the windows documentation for more information on how to change the TDR delay. https://docs.microsoft.com/en-us/windows-hardware/drivers/display/tdr-registry-keys

If Gestaltor still crashes, increase the delay further.

Gestaltor is not launching on Ubuntu 22.04​

Gestaltor is shipped as an AppImage, which expects libfuse2 support. Ubuntu 22.04 will no longer ship with the libfuse2 package by default. This means that AppImages will not run on Ubuntu 22.04 by default.

You need to manually install libfuse2 using the apt package manager:

sudo apt install libfuse2*
