I'm back

Due to some server difficulties my blog has been off line for awhile. On the list of things to recover/set up its not exactly the top of the list :-)

Making Hibernate work on Ubuntu 22.04 (jammy) on the Framework Laptop w/full disk encryption

  Making Hibernate work on Ubuntu 22.04 (jammy) on the Framework Laptop w/full disk encryption The 0th step is disabling secure boot in the bios (reboot, press F2 to get into the BIOS, disable secure boot).

It apparently works regardless of whether the user is ...
