First question here. I recently upgraded from Xubuntu-18.04 to Xubuntu-20.04. When the upgrade was finished, and I rebooted, I had no video. The monitor displayed "Out of Range" message. I found that if I rebooted into Rescue mode that I could get to a Desktop, but I was stuck on a 640x480 display that could'nt be changed.
After a lot of research, I stumbled onto a clue about adding "nolapic" as a kernel parameter. It worked. I can get to a desktop that is 1024x768 and that is acceptable. However, if I need to log out of the Desktop for any reason, the monitor again displays the"Out of Range" message. And the only way I can get back to the Desktop is to press CTL-ALT-F1 to get to a terminal login screen, login and issue a sudo reboot command.
If anyone has a suggestion as to how I can boot into the system, logout, if I need to, and still be able to login without rebooting, I would very much appreciate it. Thanks for your time.
Here is the ouput of lshw -C display:

Is this what you wanted to see, HuHa ?
Thank you all for your patience and for your answers. No matter what I did I could not get Xubuntu-20.04 to play nice on this computer. I have gone back to Xubuntu-18.04. It works. It's not a great solution, but at this point it's a necessary one. I need a computer that works.
