After sid upgrade today. 1st reboot took ages to complete. After what sddm showed no cursor. But C-A-F1 was working so I did another reboot. Then sddm took ages to show the cursor. To be on the safe side I do another reboot, but then I do not login, but instead leave the screen as is. When I come back, several hours later, I find the screen disconnected (2nd screen, display port, closed lid laptop). Again I can have tty1 and reboot. Then sddm take ages to show the cursor, but I can login eventually.
Not very convenient. Chris
