The attached pdf has photos showing the outtput of journalctl, DMESG, lscpu and
uname.
I am on fedora 40(KDE spin) and at kernel 6.9.4-200. I am pretty noob and new
to Linux.
I am running Linux on AMD A8 pro 7600B R7.
My PC was working fine until, I updated it yesterday (June 21, 2024) via dnf.
When I rebooted the GUI part had stopped working. All that I could see was a
cursor flashing on the black screen. I looked upon the internet but could find
any solution. I came across a fedora forum where a person has the same problem.
The link to that forum is provided in the URL section of bug or
https://forums.fedoraforum.org/showthread.php?332835-kwin-wayland-sddm
I got access to the tty2 via Alt+ctrl+F2 and got the logs, according to which
the Kwin Wayland segfault. I have attached the pictures of the logs in the
attachments.
Also,
According to the other person who also has same issue says that this issue is
happening on the piledriver cpu.
Reproducible: Always
Steps to Reproduce:
Rebooting after updating to the latest version on fedora 40(KDE spin)
Actual Results:
The GUI is not working (KWIN). A blank screen with flashing cursor appears.
This is the kwin_wayland error shown in DMESG.
