Version-Release number of selected component (if applicable): 0.19.0-18.el8.1 How reproducible: Always Steps to Reproduce: 1.upgrade to kernel 4.18.0-358.el8.x86_64 2.reboot 3.blank graphical login screen (black screen with mouse pointer) Actual results: blank graphical login screen (black screen with mouse pointer) Expected results: login screen OK and successful login Additional info: booting into previous kernel release all OK switching to lightdm all OK
More strange behaviour with new kernel. Although lightdm allows me to login, akonadi cannot start properly which prevents me using kmail & other PIM components. booting into previous kernel -348 all issues are resolved.
Same issue in kernel 4.18.0-365.el8.x86_64

Just incase this isn't a kernel bug, I've noticed something I can't pin my finger on. On the bad kernels, it takes a minute and a half to shut down. If you do a <Ctrl>-F12 you will see A stop job is running for Simple Desktop Display Manager (30s / 1min 30s) Which will count up to 1min 30s. So, sddm is clearly stuck on something, both starting up, and shutting down. But I can't figure out what.
Resolved with kernel update
