Kubuntu beta 21.04 installed on disk, upgraded from Kubuntu 20.10. After booting with kernel 5.11 (linux-image-5.11.0-13) if I will reboot the system, or shutdown and boot again external monitor (connected via displayport) is not waking up until SDDM is loaded - screen is turned off while grub is displayed and during whole boot process, it turns on right after SDDM is loaded and login screen appears.
This problem happens only when kernel 5.11 is in use - when I reconfigured grub so that kernel 5.8 is loaded by default and reboot system with this kernel loaded on next boot monitor is turned on propery right after turning on pc. Also after rebooting from Windows 10 (dual-boot machine) monitor works normally, so it seems that only kernel 5.11 is behaving this way.

The same situation is observed after reboting pc from Kubuntu 21.04 beta live session.
