Ubuntu 22.04 fails to show a display during startup.
Ubuntu 22.04 fails to show a display during startup.
For no clear cause, ubuntu hasn<|pad|>'s not showing any output during startup. My motherboard debug LEDs remain off. No hardware faults detected. After switching the PC to standby a few times, I reached the Ubuntu launch options and entered recovery mode. First try removed some packages, updated, ran disk check, freed space. Eventually I got back to normal Ubuntu. But the same issue resurfaced after a cold boot. This also occurs with my USB SSD using the same ISO and version. I can't repeatedly boot into recovery just to install OS. Also, HDMI didn't help; I mostly use DisplayPort. What should I do to fix this? A similar problem was reported by another user 3 days ago.
The first thing I'd check is whether ubuntu is not starting at all or just having some graphical issue; after a cold boot, when you don't see anything on the screen, try pressing ctrl-alt-f2. If Ubuntu is booted this should get you to a terminal. If you can get to the terminal it means this is either an issue with the gpu driver or a problem with the desktop environment. If you can get to the terminal it's worth a shot to restart the display manager as suggested on the askubuntu board: sudo systemctl restart gdm What are your system specs by the way?

Could be related to the reported issue on Launchpad, meaning the only option is to wait for the patch release.
Pressing ESC before the OS splash lets me jump into recovery each time. It helps me clean and fix packages every time. There are too many steps to start up, but it seems doable right now.
