eh flag

im looking to install ubuntu on my chromebook using dev mode, but i do not wish to have the white screen caused by dev mode even after installing it. After installing ubuntu can i turn off developer mode without wiping the ubuntu, or is there a way to remove the white screen from dev mode?

You cannot completely turn off dev mode unless you flash a new UEFI, but you can shorten the timeout for the screen from 30 seconds to 2 seconds.

There are two options. Run the MrChromebox.Tech script, and do one of the followings.

 cd; curl -LO mrchromebox.tech/firmware-util.sh && sudo bash firmware-util.sh
  1. You can install the full UEFI firmware. Then the current developer mode screen will be gone, and you will have to reinstall Ubuntu.
  2. Alternatively, you can choose 3) Set Boot Option, and set the timeout for the developer boot screen to 2 seconds (instead of the default 30 seconds, which is annoying). You will need to (temporarily) disable Firmware Write Protect to do this.

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.
