Re:Unexpected shut down of KStars and Ekos, but not Indi server

For Ubuntu MATE:

sudo apt -y install zram-config

It takes care of everything. If you currently have 4 GB of ram, this will give you close to 8 GB

Last night I tried my first session with my RP4 2gb running KStars on Raspbian.
Polar alignment ran perfectly and smooth (also in full screen).
Guiding ran so I started a small imaging session of 1x60s, 1x120, 1x180, 1x240 and 1x300s subs. During the 180 sub, I wanted to check the Stars on the 120 s and my messing about with the fits viewer, while guiding and taking a 180s sub, caused KStars to crash.
After restarting and reconnecting etc I tried the same imaging session again, this time leasing the poor fits viewer alone. This time no crash.
I then slewed to a New target, solved and synced and started a one hour session of 30s subs - no problems. Darks, Bias and flats afterwards without problems.
So I’ll just try not to push my 2GB RP4 too hard I did notice that my cooler fan was running pretty much all the way through my session.

Just wanted to inform that i have crashes here too. Running KStars on my ASUS VIVOBOOK with KDE Neon and Plasma.
I can sometimes trigger that by using the fitsviewer, and sometimes its just out of nothing...
But when a session is running, and i do not do too much clicking around its stable.

Same here. I don't remember crashing in another module, but most of the time if I play with the fits viewer, trying to zoom or touching the "default zoom" or anything related I crash 8 times out of 10. Very frustrating, so I try to do without using the zoom feature at all.

Hey Jasem.

ATM i use the latest stable version.
I‘ll have a try on latest nightly.

I will habe to write down how to install...
Too less linux-knowledge, used too less times...

Cheers

Last night I had a successful session with my usual setup having switched back to my Canon 450D. At first I tried my 550D, but on each of two times I tried to Polar Align, KStars/Ekos would crash just before showing the Alignment Frame I.e. at the end of the 3 plate solves. Back with the 450D and no crashes. I noted a significant difference in the solving times between the two cameras 9 secs for the 12Mpixel 450D, twice as long for the 18Mpixel 550D. Next clear night I’ll try out my RPi4 4GB rather than my 2GB, although the latter is housed in a flirc case and stays very cool outside with no fan.

does the software updater on the pi4 os check for the nightly builds ?? if not, how do you set the pi4 updater to check the nightly builds ?

The terminal commands to go back and forth between stable and nightly are here:
indilib.org/download/ubuntu.html

I haven't looked at the Stellarmate OS lately so I'm assuming it is still Ubuntu....

I still have random crashes on the Pi4 using nightly from 10/7. FITS viewer was open, so that could have been the problem.

Sorry, only just now saw this post from you, Jasem. I will run gdb backtrace next time that happens.
