As we have seen here, Fedora Kernel 6.10.8 is presenting a phantom display. We have an active bug report with Fedora filed. I am actively working with the Fedora team to monitor this.
In the meantime, there are few different approaches to pinning your previous kernel. I recommend trying to pin by index. This means if there is a kernel update, the new kernel will right itself upon the new kernel install. However, I have also found that grubby doesn’t always get the job done. So I have another method that does work. And, when a new kernel comes out, the “correction” script is included in the same KB doc.
This has been translated for English, other languages may need updating showing the old (non-working) approach. I will get with our escalations specialist to make sure this is translated.
Guide: Change Default Fedora Kernel
This is the kernel default pinning guide. Examples reflect 6.10.8 and 6.10.7 - you want to be on 6.10.7.
Project Bluefin and Bazzite users: You want to be on the default releases provided by Bluefin gts or stable and Bazzite stable.
