Switched to 24.04 the day it was released.
FP4 here with UT installed on it within 30minutes after unboxing the phone.
I's actually really nice and things started working better from 20.04.
Some still don't, like the notes app but heh... there is nano and vi at hand.

There are two things that I'd like to debug and I'd apreciate guidance as I'm a long time *nix enthusiast but this halium and lomiri stuff is very new to me.

WiFi hotspot: cannot connect anymore. Looks like UT does not run hostapd and I don't know where to look for logs and strace the process.
So.. where logs? nm by any chance?

And a second nag, the backlight is dimmed to zero at random times. Fades back to previous value by tapping the touchscreen. /sys/class/backlight/brightness is 0 when it happens.
What process manages the backlight? And is there any other means of interfacing the backlight control other than sysfs interface?

And, maybe a bit off topic, I'm searching like a blind dog in the lomiri-camera-app code for the camera switching parts and I just can't see where is that function. You know... rear/front switch. A file name and a line number would be awesome.
