| alkisg | Good morning everyone! The following card only works with "nomodeset" in 18.04, even with 4.20 kernel, any ways around it? | 07:02 |
|---|---|---|
| alkisg | 38:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Raven Ridge [Radeon Vega Series / Radeon Vega Mobile Series] [1002:15dd] (rev c6) | 07:02 |
| alkisg | Subsystem: Advanced Micro Devices, Inc. [AMD/ATI] Vega [Radeon Vega 8 Mobile] [1002:15dd] Kernel modules: amdgpu | 07:02 |
| alkisg | I also tried the x-swap ppa, with no noticable changes | 07:05 |
| alkisg | Hmm, I didn't try xserver-xorg-hwe-18.04, would that help? | 07:24 |
| tjaalton | no, since it's a kernel bug? | 08:16 |
| tjaalton | alkisg: what's the exact issue? | 08:17 |
| alkisg | tjaalton: the school reports black screen with the default settings, and limited resolutions with nomodeset | 08:17 |
| tjaalton | try amdgpu dkms from the amdgpu-pro tarball | 08:18 |
| alkisg | I thought the card was too new and it would need a newer kernel or something, so I tried -hwe first and 4.20 after, with no changes | 08:18 |
| tjaalton | i have a laptop with vega 8 mobile and it works fine | 08:18 |
| tjaalton | so it's not a generic failure | 08:18 |
| alkisg | Thank you, will do when the school contacts me again | 08:18 |
| alkisg | Gotcha | 08:18 |
| tjaalton | works with stock bionic too | 08:18 |
| tjaalton | if the dkms is still busted, it's best to file a bug upstream too | 08:19 |
| tjaalton | or you can build the kernel using https://cgit.freedesktop.org/~agd5f/linux/log/?h=amd-18.50 | 08:20 |
| tjaalton | q | 13:20 |
| tjaalton | uh | 13:20 |
