Another option would be to disable Intel graphics (in Firmware) - if possible and then run NVIDIA's proprietary driver. But I'm not sure, whether the hardware supports this (for all needed outputs).
Do you mean disabling the Intel GPU in the BIOS ? It is not possible with this laptop.
That's why I wrote *if possible*. ;-) Obviously, this is not an option on your system then.
Eventually, by following [1] and [2], I could fix the fallback issue by setting the kernel parameter "i915.enable_guc=1". This option apparently enable advanced drivers for recent Intel chipsets. Following [2] advices, I also added enable_rc6=1, enable_fbc=1, enable_psr=1, disable_power_well=0 and semaphores=1. That seems not to have introduced any regression in my use cases. Either under Wayland and Xorg.
So the bug report can be considered fixed from my point of view (although my external screen is still not detected, which is odd because Ubuntu 17.10 does it, but that's another story). Unless you need more info/logs from me ?

Well, I would call this a workaround, not a fix. Seems option "i915.enable_guc=1" is enough to fix the issue for you, right? -- You are receiving this mail because: You are on the CC list for the bug.
