UPdate 2023-09-10: Avoid black screen on Ryzen 7

Support Graphics & Display
1

Reading the actual announcement, I found for the UPdate 2023-08-11 the topic “Avoid black screen on Ryzen 7”
Based on the solution from @linux-aarhus was recommended:

You may be able to avoid black screen if you - prior to rebooting after the update - sync the latest stable kernel - currently - Linux 6.5.

My machine has a AMD Ryzen7 Pro 4750U and my kernels are

$ mhwd-kernel -li
Currently running: 5.15.128-1-MANJARO (linux515)
The following kernels are installed in your system:
   * linux510
   * linux515
   * linux54

Actually, I don’t need a newer kernel. I’ve done the update 2023-08-11 mid August without any problem.
But, in regards to the issue, I’d appreciate your recommendation? I haven’t starte the actual UPdate yet …
Thank you!

Black screen after update. No possibility to tty

Pretty sure that issue was only affecting people with 7xxx graphics cards.

Although, removal is expected - it has to marked EOL on kernel.org - then will be taken down - so if you are indoubt - add linux64 to the pacman package list

Assuming an up-to-date mirror - otherwise refresh mirrorlist - using Global pool

sudo pacman-mirrors -c Global
sudo pacman -Syu linus64 linux64-headers

You may want to install 6.5.2 kernel from unstable branch to fix this issue.

Thank you @linux-aarhus and @philm, but that overwhelms me:
Mod edit: uploaded image(s) removed

  • 6.4 plus 6.5 or 6.5 only?
  • Install or use that kernel?
  • How to install from unstable branch without changing the branch completely?
  • Any “easier” option?

Since the issue "Avoid black screen on Ryzen 7… " is listed under the UPdate 2023-08-11 which i’ve done without any problem, is it likely to have a problem now?

Do nothing and carry on as usual. Your system is not affected.

well, 6.5 kernel series has an issue which may produce black screens on Ryzen APUs. If your older kernel doesn’t have it no issue there. Kernel 6.5 black screen regression — Linux Stable Kernel Updates

Thank you @philm. I’m not sure that I understand the full story, but @brahma mentioned my question to an issue of an AMD-User running 6.1.19-1-MANJARO (linux61), e.g. not 6.5 kernel.

  • Can we find out, if 6.* kernels are the problem and 5.* kernels are safe for this issue?
  • Can you foresee, when a fix for the 6.? will be available?

I’d appreciate your recommendation for my next steps; currently I’m delaying the UPdate …

I have no idea why you are trying to stick on older kernels with newer hardware.
If I were you I would be chasing 6.5+ as best I could.
(not to mention 6.4 brought a number of advances, like ext4 getting faster)
I also dont think your device is one of the ones affected by this issue.
Even if it were … you have multiple kernels installed.

So, if I were you I would:

Go ahead and install the latest available (6.5) along with your updates
(sudo pacman -Syu linux65 linux65-headers)

Then … reboot, check the newer kernel … if black screen then reboot and use an earlier one.

(and once you are happy and comfortable … go about removing excess kernels until you have 2 or 3 total, ex: 5.15 & 6.5)

I afraid my problem not in the kernel (or not only in the kernel). For me it doesn’t work even with 4.19. 5, and 6 (6.1, 6.4, 6.5) also show black screen. What I able to reproduce, that problem in something that changed between 22 and 23 snapshot, because I can easily reinstall 22 from USB (everything breaks after update), but cannot even start USB with 23.
