Hey folks!
I’ve recently installed Debian 12 on my Librem 14, replacing the original PureOS installation. Most things are working fine, but I’m experiencing a few issues related to power management. I’m sort of guessing they’re related to the EC firmware because upgrading that solved power management issues in the past, but I could be wrong.
- Plugging in headphones when the laptop is on battery power sometimes causes a hard shutdown.
- I could have sworn that I fixed this in the past by upgrading the EC firmware, but I verified using the steps at Librem-EC on Purism Devices – Purism that the OS reinstall did not affect the EC firmware, it’s still at version 1.13.
- The “start charge threshold” and “end charge threshold” settings in
librem-control
are not being respected.- I previously installed
librem-control
on the PureOS installation and set the thresholds to 60% and 80% respectively. That was working fine. - Now, on the Debian installation,
librem-control
is not available directly in the package repos, so I downloaded it from here. However, while it runs, it doesn’t seem to have any effect, e.g. I changed the thresholds to 90% and 100% but it’s still the old thresholds (60% and 80%) which are being respected.
- I previously installed
- The keyboard shortcuts to change brightness stop working after a while (fixed temporarily by a reboot).
sudo light -S N
still works, so I suppose this could be an unrelated software issue.
Any suggestions for how to resolve or further diagnose these issues?
