Public bug reported: I have had the screen go blank several times. Each time that this occurred, I was selecting the "Settings" item from the upper right corner arrow. Perhaps there are a lot of low level accesses that occur when this menu item is selected that somehow locks up the ASPEED AST driver or some other part of the display? When this problem occurs, the only way I have been able to recover is to power cycle the system. The info collected for this bug report was taken after rebooting the system.
I originally had a problem that the initial login screen did not display (blank screen) but I came across the following that provided a solution of disable Wayland: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1872091 I am not able to reproduce the problem at will. I can usually access the "Settings" without a problem. However, each time the screen has gone blank it was right after clicking on the "Settings" menu item. I have six identical machines (Supermicro SYS-5019C-FL) and this problem has occurred on several of them.
