https://bugs.freedesktop.org/show_bug.cgi?id=108521 --- Comment #51 from Robert Strube --- Hello Everyone, I realize it's been a long time since I updated this bug report, apologies in advance. I decided to give up on eGPUs + Linux (over Thunderbolt 3) for a while, and didn't get a chance to really tackle the problem again until more recently. Since my initial report, I have been able to get an eGPU working with my Dell XPS 9575, but only with a Nvidia GPU (specifically an RTX 2070). I did try another AMD card, but ran into the same problems. I'll attach my dmesg and lspci information in the hopes that this might shed some light on why the nvidia GPU works correctly (albeit with the proprietary driver) and certain AMD GPUs don't. -- You are receiving this mail because: You are the assignee for the bug.
