I have had my Udoo Bold Gear for over a year and it's been working great running the latest Ubuntu release. I recently started to notice that the screen will go black and basically all UI is not accessible. I can connect to the server via a remote ssh shell through another computer and the Linux commands work fine. If I reboot from my remote ssh connection, the connection drops which implies the the reboot is started but the reboot never completes and I have to do a hard reset or pull the power to get it to reboot. I have seen it go black one time while I was using the computer but most of the time I have seen it when I am get back to the desktop and turn on my monitor or if the monitor. I have also noticed this when the screen is black while in power safe mode in the monitor is active. Has anyone had this issue? I don't know if this is hardware or bad memory RAM or M.2 NVMe SSD or an O.S problem. Anyone has had this happen? Any help would be appreciated. Thank you.
