gpu-manager should be disabling UBB when using nvidia proprietary drivers on Quadro based chipsets

Asked by Sidrew on 2020-10-10

Is there any way to get gpu-manager to disable the UBB feature of the proprietary nvidia drivers when using Quadro chipsets? This is recommended by nvidia in such a configuration when trying to run vulkan based games. Surely gpu-manager can detect this and disable it, no? From the nvidia driver search page:

Known issue:

Vulkan with flipping enabled on Quadro cards can lead to graphic corruption. If you think you have run into it you can do either of the following as a workaround:

- Disable flipping in nvidia-settings (uncheck "Allow Flipping" in the "OpenGL Settings" panel)
- Disable UBB (run 'nvidia-xconfig --no-ubb')
- Use a composited desktop

Well, I'm not an Ubuntu dev, but to me, it wouldn't make sense to disable UBB or flipping by default if they help with performance, unless a lot of Quadro users are having problems with Vulkan.

Also note that Ubuntu's default desktop/WM (GNOME/Mutter) as well as many of Ubuntu's "flavors" use compositing by default, which should make this much less of an issue.

If you're looking for a definitive answer, it's probably better to file a bug if you still think UBB should be disabled by default.

Can you help with this problem?
