So I just installed Garuda. I can’t see my leds or my backlight control. I can see capslock and numlock, and something called phy0-led but i can’t see where that is being controlled.
Do you know if there’s something I can install or do to access my leds and kb backlight?
I do not know about Garuda but first requirement is that you install and activate the absolutely required ACPI DKMS package. Without it there is no driver for the functions. In PureOS this is the “librem-ec-acpi-dkms” package.
You can also control the notification LED using sysfs directly, also using triggers, see the referenced blog post and the section “Controlling the Notification LED”. The notification LED follows the current freedesktop.org nomenclature for such a notification LED so it can get picked up by services. On the Librem5 phone Phosh is using this service to light up the LED when desktop notification messages are available, just as an example. We are working towards enabling this in regular GNOME too.
k thanks. I wonder what it will be like. I’ve never seen that light light up.
Also, I wanted to ask about your charge strategy from 40 to 90. I was weirded out by machine being plugged in, stuck at 52% without charging. Can you explain what your thinking was to not make the lower threshold 90 and the upper thresh 100?
To see what it looks like I gave examples in the blog post
For the battery, the thing is that batteries do not like to be charged too often. So recharging a battery to a high percentage or worse 100% all the time will shorten its lifetime. I usually do not need a full charge so I can totally live with the battery just having 50% or less since most of the time I have the charger connected. I also only charge to 90% since charging to 100% would again shorten the battery life expetancy. If I know I need to go on a longer trip without charging possibilities (say, a bus ride), I can deliberately charge to 100% just this one time.
There are no general rules. What I can say is that any use of the battery, be it charge or discharge, will age the battery. Charging to 100% is not advisable, if possible I would not charge to more than 90% on daily basis. Also discharging to really lo levels is not good, always recharge when below 20% (if possible). And if you can avoid it, do not charge again whenever connected to the charger. It is perfectly fine for the battery to stay at, say, 50% or 60%.
Like I mentioned before I have my defaults set to 40% start threshold and 90% end threshold, which I am totally fine with.
Thanks! My Librem 14 arrived with start threshold set to 23%. Do you think this is either the best or a good choice for Purism to use when shipping L14s?
