install linux on chromebook without developer mode

Press and hold the Esc + F3 (Refresh) keys, then press the Power button.Re-install ChromeOS from the recovery disk.So the current process for installing a C720 from scratch is: In /etc/pam.d/common-auth, change ecryptfs from optional to required.Ī reboot is required before the fix becomes effective.Comment out the lines about ecryptfs in both /etc/pam.d/common-password and common-session-noninteractive.Mint 21 still has this problem, but the fix described here works: Because of this issue, please be aware that in Mint 20 and newer releases, your encrypted home directory is no longer unmounted on logout. The move to systemd caused a regression in ecryptfs which is responsible for mounting/unmounting encrypted home directories when you login and logout. But there's a problem there that Mint 20 inherited from Debian's switch to systemd: Since full-disk encryption is unusable, the alternative is home directory encryption. The problem that appeared on Chromebook Linux wikis back in 2014 has re-appeared:Īfter a resume /var/log/kern.log is continually spammed with messages from ehci-pci saying resume error -19.So if I can live with just home directory encryption I can resume working with a current kernel. Without full-disk encryption the system sleeps and resumes correctly, and can be shutdown and rebooted.With LVM and full-disk encryption the system sleeps and resumes correctly, but the problem that appeared with kernel 5.4.0-42 is still present, namely that with full-disk encryption the second cold-boot of the system fails having apparently flipped the developer mode bit so that the BIOS refuses to boot the non-Chrome OS.

Installed Mint 21.1 from scratch without full-disk encryption and with encrypted home directory, and updated to the current 5.15.0-67 kernel.īelow the fold, my notes on these experiments.Installed Mint 21.1 from scratch with LVM and full-disk encryption.I was becoming a little concerned by the fact that the 5.0-series kernel I was stuck with was getting long in the tooth. Below the fold I have some good news and some no-so-good news. The three Acer C720 Chromebooks I wrote about in:Īre all still running Linux just fine despite the one I'm typing on being more than 8 years old.
