Using update manager to update kernel 5.0.0-37-generic to 5.3.0.26.95 defaults to laptop display
by daches from LinuxQuestions.org on (#4Y3Z0)
Yesterday, I applied several updates using the update manager. The list of available updates included the captioned upgrade for the kernel. Upon rebooting I could no longer use the GUI,and was barely able to use Timeshift
from the terminal to restore my system to a functional state. One of the updates included something involving graphics, so I thought that might be the problem. So I then installed all the upgrades EXCEPT the kernel, and the system still had a proper display when I rebooted. Then I applied the kernel update, and again could not use the display effectively. It defaulted to laptop resolution, and all the buttons for changing parameters were grayed out.
At the moment I am back on 5.0+. I noticed that the current stable version is 5.5+, but the upgrade manager does not offer that.
