Ubuntu 22.04 LTS screen blank does not respect settings

cn flag

OS: Ubuntu 22.04.1 LTS

Whatever settings I make to Screen blank (never or 15 minutes) the screen goes blank after 1 minute. It's very annoying, sometimes while reading an article if I don't move the mouse or press any key it activates screen blank (it doesn't ask for password, but I have to move the mouse or press any key to get it to come back).

My Power settings

Automatic Suspend On Battery Power & Plugged In set to 20 minutes

Try using dconf editor and set the desired value in `org->gnome->settings->daemon->plugins->power->sleep-inactive-ac-timeout`. At least you have an annoying setting, my one made the screen blank non-functional which caused a component in my laptops display panel to burn out. I had eventually figured out you can set `sleep-inactive-ac-type` to configure the behavior, mine was on `'nothing'` which is not a great one.

I'm on uBuntu 22.04.2 LTS and changing the recommended dconf settings do NOT affect the problem screen blanking. The blanking is immediate and occurs after 30 seconds. None of the settings are set to this value. I have selected 10 minutes for dim Screen in Settings. In dconf I have set: sleep-inactive-ac-timeout to 7,200 sleep-inactive-ac-type to nothing sleep-inactive-battery-timeout to 2,400 sleep-inactive-battery -type to suspend None of the above settings change the behaviour. This problem just started occurring in the last few days.

Since adding my comments I disabled: https://ppa.launchpadcontent.net/graphics-drivers/ppa/ubuntu/jammy main and then sudo apt-get update sudo apt-get dist-upgrade Now the display is staying on appropriately.
I sit in a Tesla and translated this thread with Ai:

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.
