I’ve installed Ubuntu 22.04 onto a PC I just built. I had to boot with (safe graphics) to get through the installation, and when the newly-installed OS booted, it had the same behavior as the installer: it boots to the desktop, but only draws the background image (a low-poly purple jellyfish).
I walked away to eat lunch, and when I came back, the display was asleep. Tapping some keys woke it up, but it was blurred. On a hunch, I typed my password. Sure enough, the desktop redrew unblurred.
So it seems just the UI elements are not rendering, implying a graphics issue. Unfortunately, I can’t seem to get back to a (safe graphics) reboot option. If I hold shift after resetting the machine, I get two choices: Ubuntu or Advanced Options. Avanced Options led me to a recovery mode option, which gave me another menu that included “resume,” but no “safe graphics” mode. I chose to resume, and held Shift down to try to get back to the original menu. But instead it booted into a safe graphics mode, characterized by a really low-resolution display with incorrect aspect ratio.
I need help sorting out the graphics driver, I think. The board is a standard version Axiomtek MANO521, with an Intel i3-9100 CPU with on-board graphics. The HDMI-connected display is a UPERFECT 2560x1440 that seems to be discontinued. But the Settings app shows “Unknown Display” and doesn’t let me change anything about it.
Is there a configuration I need to adjust, or a driver I need to install?
