Hi All, |

A few months ago I bought a AMD RX 480 GPU and followed the Gentoo |
| 4 |
amdgpu guide and everything ran just fine with excellent graphics |
| 5 |
performance. |

At the weekend I upgraded my PC from a AMD 970 chipset to a x370 |
| 8 |
chipset (fx8300 to ryzen 1700x). |
| 9 |
|
| 10 |
I re-installed Gentoo but the first time I started the boot iso the |
| 11 |
screen froze, so I tried the nomodeset option and booted ok and |
| 12 |
installed as per usual. |
| 13 |
|
| 14 |
After rebooting to new install the screen froze again and the only way |
| 15 |
to get it to boot was using kernel option nomodeset. This then gave me |
| 16 |
another problem as it could not startx (no screens found). |
| 17 |
|
| 18 |
I checked the config of the kernel (inc firmware) and could not find |
| 19 |
an issue. I then tried arch/fedora/ubuntu and all froze at boot and then |
| 20 |
worked with nomodeset. |
| 21 |
|
| 22 |
I have now gone back to using an old graphics card which uses radeon |
| 23 |
and have no problems starting xorg-server. |
| 24 |
|
| 25 |
1) Is this likeley to be a kernel issue (amdgpu drm)? |
| 26 |
2) Could this be a firmware issue (amd)? |
| 27 |
3) Could this be a motherboard/processor issue? |
| 28 |
4) Can you think of any ways round this so I can use the RX 480 gpu |

Any thouhgts much appreciated. |
