Having a black screen after resume issue with the latest update (Kernel 5.14.7-2).
Went back to the older linux-firmware and kernel 5.13.19-2-MANJARO. Now it works!
Operating System: Manjaro Linux
KDE Plasma Version: 5.22.5
KDE Frameworks Version: 5.86.0
Qt Version: 5.15.2
Kernel Version: 5.14.7-2 MANJARO (64-bit)
Graphics Platform: X11
Processors: 8 × AMD Ryzen 5 3400G with Radeon Vega Graphics
Memory: 13.6 GiB of RAM
Graphics Processor: AMD Radeon™ Vega 11 Graphics
513 is EOL, best is to install 510 and 514
if error with one after update, we select other in grub
We’ll all have slightly different criteria, but I’m sticking with linux513 (for now) for 2 reasons:
- As a “bleeding edge” AMD CPU (5600X) & GPU (6800XT) user… 510 is lacking (IMO 512 is the minimum kernel for my hardware) and 514 still has some growing pains in the newly available 5.14.7 kernel… [WARNING][AMDGPU] Oops in Linux 5.14.7
- linux513 is still the default kernel provided with the new (non-54) Pahvo 21.1.4 ISO’s
Your system, your decision, your responsibility and why I’m on 5.10 LTS…
Here is where you can find this information
I found the solution here: https://www.reddit.com/r/archlinux/comments/qkoolz/linux_51415_breaks_display_modesetting_on_ryzen/
Needed to enable IOMMU.
For my Board (Asrock B450M Steel Legend) I found this setting in the BIOS:
Advanced > AMD CBS > NBIO Common Options > NB Configuation > IOMMU (enable)
