| Summary | On Ubuntu Bionic with kernels 4.15 and above, RX480 Displayport outputs don't work (dmesg reports "not connected) |
| Product | DRI |
| Version | unspecified |
| Hardware | x86-64 (AMD64) |
| OS | Linux (All) |
| Status | NEW |
| Severity | normal |
| Priority | medium |
| Component | DRM/AMDgpu |

Anything from at least 4.15 up to 4.17-rc1 under Bionic makes the Displayport connections fail to even detect a display, while anything 4.14.x works and detects it perfectly. Is the PCI ROM error related? Is this a duplicate? I can provide xorg logs later today.
