hey Paul, did you use realVNC client or you swapped the server to it?

composition is disabled by default, the interesting thing is that enabling it, animations look smoother :D

yes. the tasks are something that are spawned and managed by the kernel itself, it is the kernel itself which decides for example how many kworker to spawn (those are the one that do actual job on the computer), KDE spawns few processes as well (I believe but take this with a grain of salt, more than XFCE) but the kernel we are running on AA is waaaaaay more recent than the one from AB (and also 20% more efficient in multitasking, I don't recall if that happened in version 6.1 or 6.2)

It is hard to reach a sweet point between ready to be used out of the box and being light but we always try to evaluate every thing from both perspective (for example, the gps daemon is turned off by default cause not everyone will be using that).

I believe most of those tasks are actually used by useful processes but I will look into this by myself to see if there is something else that may be disabled at boot time bv default!

Thanks, will add this to the documentation!

Hi Paul, the answer is at the same time yes and no. From a pure desktop perspective KDE Plasma is definitely more resource hungry than xfce but overall this is not impacting the astro suite as it won't re-draw stuff.

While I can't say I had bad experience with my Pi4 8GB I know for example running AA on a pi3 is impossibile due to resource constraints.

Also to note, the pi5 runs KDE plasma incredibly smoothly

If you are worried KDE will slow down things rest assured it won't, but I get the point it is not xfce; I still like it very much and I chose it cause of the more modern look and feeling

Mattia replied to the topic 'aa mantainers' in the forum. 3 weeks ago

since I have been pulled in, I'd like to clarify that while I am the "main" character behind astroarch and being using mostly FOSS since forever I know very well why is SO BAD to have a one person project.

AstroArch can be considered mantained by at least 3 people and rest assured, if I should die tomorrow Stephan will be able to release new versions the same way I did till now :D

I am also considering mirroring the repo where I host pre-compiled package and have multiple owners for that.

From that pov I think AA is in a slightly better position

Hi Steve, had a look at the logs, they look mostly normal to me, and if the ttyUSB1 stays that way I wouldn't bother too much, got some questions:
- do you have a so called eqmod cable? it seems pl2303 may look like one and the eqmod chip may cause problems on Linux (I recomment in fact using normal USB cables)
- are you running through a powered USB? The lines containing "over-current change" indicate that whatever device is there is requesting more current than the pi may provide. Can't tell for sure what kind of device is there, you may have more luck adding usb_max_current_enable=1 in /boot/config.txt

That was my first guess Steve, yes.

ZWO (bit more generically all dedicated cameras) do nor use serial ports for communication but rather their own SDK and some libusb magic to find them.

when you say nothing in dmesg, have you tried to pull the cable off and reconnect to see if anything happens on the usb bus? can you also post the output of lsusb?

hey Steve, when something like what you see happens it likely means the device gets disconnected (reasons here can be vary, but most often than not is about voltage drop)

May I suggest to open a terminal and run sudo dmesg -w

It will tail all kernel logs and you will see any action taken against your devices. That should help at least identifying the root cause
