I just installed Ubuntu 18.04 on my Thinkpad 11e recently and have been learning what I can do with the command line.
I just learned about
tlp and installed it to manage my battery life. I also learned that setting charging thresholds and calibrating the battery is possible on some Thinkpads using tlp, so I installed
acpi-call-dkms with the hope of learning to use these functions.
tp-smapi I was prompted to create a user-key for the program, so I learned about secure-boot mode and decided to disable it. I uninstalled
acpi-call-dkms, disabled secure-boot using
and rebooting to switch off secure-boot mode.
Now just before booting the screen displays 'booting in insecure mode' or something like that, so it seems that worked, but when I reinstalled
tp-smapi-dkms I was still prompted to make a user-key (
acpi-call-dkms didn't do this for me either time), so I went ahead and did that anyway. Now after all that, neither of these packages are enabled, and I have also since started to doubt that my hardware supports either of these packages.
- Does anyone know if a Thinkpad 11e can run these, or am I wasting my time?
- If it is possible, why are they still not enabled?
- Also can anyone make sense of why I was prompted to make a user-key even after disabling secure-boot?
This is my output for tlp-stat -b:
