Thank you for taking the time to report this bug and helping to make Ubuntu better. It sounds like some part of the system has crashed. To help us find the cause of the crash please follow these steps:
1. Look in /var/crash for crash files and if found run: ubuntu-bug YOURFILE.crash Then tell us the ID of the newly-created bug. 2. If step 1 failed then look at https://errors.ubuntu.com/user/ID where ID is the content of file /var/lib/whoopsie/whoopsie-id on the machine. Do you find any links to recent problems on that page? If so then please send the links to us. 3. If step 2 also failed then apply the workaround from bug 994921, reboot, reproduce the crash, and retry step 1. Please take care to avoid attaching .crash files to bugs as we are unable to process them as file attachments. It would also be a security risk for yourself. ** Package changed: xorg (Ubuntu) => ubuntu ** Changed in: ubuntu Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1924583 Title: ASPEED AST driver seems unstable in 20.04.2 LTS Status in Ubuntu: Incomplete Bug description: 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.
