Dear Linux folks,
It looks like, that loading a graphics driver, the DRM methods probe each connector.
For example, the Asus F2A85-M PRO has four monitor ports, but only one monitor is connected over DVI. Here is the log excerpt with Linux 4.18-rc6+.
[...]
If I am reading the logs correctly, probing the non-connected ports is not done in parallel,
It could be, though. That would probably be the best solution.
On desktop systems and often with laptops (mostly no external monitor connected) the setup doesn’t change that often.
Still, the driver missing when it does change will make for an unhappy user.
Is it possible to pass options to the driver to not probe certain ports during startup?
