https://bugzilla.suse.com/show_bug.cgi?id=1222213 Bug ID: 1222213 Summary: sddm-greeter-qt6 crashes on startup if used with kernel driver "radeon" Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: x86-64 OS: openSUSE Tumbleweed Status: NEW Severity: Normal Priority: P5 - None Component: KDE Workspace (Plasma) Assignee: opensuse-kde-bugs@opensuse.org Reporter: 42.rantanplan@googlemail.com QA Contact: qa-bugs@suse.de Target Milestone: --- Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:124.0) Gecko/20100101 Firefox/124.0 Build Identifier: Booting the system ends in an unresponsive login screen. The cursor in the password form does not blink. Interaction with the login screen (mouse clicks, keyboard input) is not possible. Logs contain a coredump for process sddm-greeter-qt6. When booting with kernel options "radeon.si_support=0 amdgpu.si_support=1", sddm-greeter-qt6 works as expected. Reproducible: Always Steps to Reproduce: 1.boot tumbleweed system with sddm display manager 2.wait until login screen is displayed Actual Results: login screen is unresponsive, graphical login is not possible Expected Results: login screen accepts password and allows login Note that the following data has been collected after switching to driver "amdgpu", hence this is the data of the working system. The actual crash happens when using driver "radeon".
