I can reproduce an issue I am having with my external display, connected through a thunderbolt 3 dock to my laptop (a Framework 13, intel 13th gen). The issue happens when I boot the latest kernel (6.4.13-200.fc38.x86_64), but the issue doesn’t happen in the previous one (6.4.12-200.fc38.x86_64), and hence it may be a regression in the kernel or some modules (video, thunderbolt,… IDK).
Before entering in the details, please note that my question is where to open an issue (here? Kernel? Kernel who --Fedora’s kernel team, Linus’ team / module maintainers?) and, based on your experience, what data do i need to submit for the submission to be taken in consideration effectively. And, of course, where to look to to check whether this issue has already been filled.
The issue I am having is that with the latest batch of updates.
- if I boot in the latest kernel the external display gets blank and suspends itself after 3 seconds of displaying the desktop.
- However, the laptop still senses that there may be something receiving a signal, as the display set up doesn’t fall back to a situation where all applications are represented in the integrated display --it sends them “into the void”.
- As I said, booting in the previous kernel gets me a smooth and stable connection with the external display
- This happens regardless I switch to External Only, Laptop Only, Mirrored or Extended display setup.
So: who do I reach out with more data about this? Thanks!
