Updated to 22.04 LTS → Boot now stuck on '[...] HDMI/DP requires binding with gfx driver

ro flag

After updating from Ubuntu 20.04 → 22.04 LTS I am unable to boot. Upon boot the following text keeps blinking:

/div/sda5: clean, xxx/xxx files, xxx/xxx blocks
[64.xx] snd_hda_intel 0000:00"03.0: HSW/BDW HD-audio HDMI/DP requires binding with gfx driver

Hardware: Gigabyte BRIX (Intel HD Graphics 5500).

Is anyone familiar with this issue? I am able to login using SSH.

EDIT: I found out what may have caused the issue. Because I use Ubuntu without a monitor I used the information in this post to setup a dummy display. However before the update I reverted these changes (i.e. by removing /etc/X11/xorg.conf) because with the dummy display enabled, regular displays do not work. After re-enabling the dummy display I can now see the Ubuntu again (over TeamViewer). However, still no output on physical displays. Does anybody have an idea how I can properly disable the dummy display so that I can access Ubuntu through a physical monitor again?

A Ubuntu Core 20 system should be upgraded to Ubuntu Core 22 and not 22.04 LTS. The Ubuntu products using the *year* (20) format are specialist products and differ to the far more widely used *year.month* (20.04) products. The upgrade of 20 to 22 involves no user package changes, where with 20.04 to 22.04 all packages get upgraded; ie. they are different systems.

Hi @guiverc, I actually upgraded from 20.04 → 22.04 but made a mistake in my initial post. It has been edited.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
