Problem Description:
When booting Ubuntu the screen goes blank right about when I’d expect the login screen to appear with the monitor entering power save mode.
The problem occurred pre-install when booting via the USB medium and selecting Try or Install Ubuntu, though the system startup sound played, indicating the OS was alive. As a workaround, I successfully completed the installation by selecting Safe Graphics Mode. The problem occurred again post-install and is still persisting.
Relevant System Information:
Ubuntu 24.04.3
Linux 6.14.0-37-generic
Lenovo ThinkStation P8, AMD Ryzen Threadripper PRO 7975WX, AMD Radeon Pro W7600
What I’ve Tried:
I’ve tried installing Ubuntu 22.04.5 LTS but am facing the same problem there.
I’m able to boot into Ubuntu either via the recovery mode or by adding nomodeset to GRUB.
I’ve tried installing the amdgpu drivers from AMD’s website, though this made matters worse not allowing me to boot into Linux at all.
I’ve tried adding amdgpu.dc=0 to GRUB as suggested in a recent thread here without any success.
What I Haven’t Tried
Installing a newer version of the kernel as suggested in one of the posts below as I’m new to Linux and not quite sure how to best do this / whether this might break things down the road.
Thanks @Actionparsnip for the tip. I had used the nomodeset option to boot into Ubuntu to install updates and try out additional AMD drivers, but unfortunately I wasn’t able to fix the issue this way.
