Hi Jasem

I just updated ekos and indi from the PPA, but I can't see any change in the Ekos Mount tap... Any chance that your change in git hasn't gotten into the PPA yet?

Hi Jasem

I think the Stellarmate project is a great idea!!!

I am however using an Odroid XU4, because this device provides both gigabit ethernet and USB3 ports, all of which is very nice to have, especially because the USB3 enables me to upgrade to the newer astro cameras using USB3 and actually take benefit from the improved speed of the USB3 port...

So I was wondering if you would consider providing a third option/way for people to get and use Stellarmate. I would like to be able to get all the nice tools you provide with the stellarmate system, but I'd like to run them on my Odroid XU4. I'm completely ready to handle the OS part myself (currently running Ubuntu 16.04), I would just like to be able to get all the Stellarmate functionality, and I wouldn't mind paying for them!

Who knows, if it works really well, perhaps you would like to provide an OS image for Odroid with Stellarmate as well...

Best regards
Anders Lange

I can see that I can actually make different scope configurations in the EQMod driver, it seems to support up to 6 different (Main + Guide scope) configurations.

It just seems to be important that the equipment profile selection of primary + guide scope matches that of Config#1 else it will be overwritten... when connecting to the equipment.

Would it be possible to add support for switching between these (max 6 scope configs) in the Mount tap in Ekos? It already displays the scope data for the currently selected scope config, and it updates just fine when I switch to another config in the INDI control panel. But it would be much more user friendly to be able to this from the Ekos mount tap directly! Just a suggestion ;)

Hi Jasem

Thanks for the quick reply! That's also the procedure I arrived to, but it would be VERY nice if it was possible to configure more than two scopes for a single equipment profile! Would such a feature be hard to add???

A second question regarding equipment profiles and equipment configurations, is it possible to export the profiles and configuration data, so it can be imported again later i.e. after a re-install or on another device e.g. from a PC to a Raspberry Pi? It's OK if I need to do it by hand, but where do I find the correct files? An automatic import/export feature would of course be preferable...

Best regards

Hi Jasem

How should I configure Ekos, in order to use my Polemaster for polar-alignment?

This is my setup:
Skywatcher NEQ-6 Pro
Imaging scope: GSO RC6 with Canon 650D (FOV = 0.93° x 0.62°, FOV with 0.64x reducer = 1.45° x 0.97°)
Guide scope: TSL60D (60mm aperture, 240mm focal length) with ZWO ASI-120MM (FOV = 1.14° x 0.86°)
Polar alignment scope: QHY CCD Polemaster (FOV= 11° x 8°)

Best regards
Anders Lange

So I've tried installing the x2gomatebindings package, as well as altering my x2go client profile... but is dosn't work... I still get the same error :-(

But luckily I stumbled over Xpra during a google search... and it works really well, it's not as nice as X2Go, but it comes very very close and the performance is great.

So for now I think I will just be using Xpra instead :-)

Hi jpanana

Thanks a lot for your input. I can see that I might be missing the x2gomatebindings package... I only installed the x2goserver and x2goserver-xsession packages on the server (Odroid XU4).

But I can also see that you've configured your X2Go session somewhat differently from me..., so maybe there is a possibility of success if I change my X2Go session confiuration slightly...

I'll give a try as soon as possible :-)

Again, thanks for your input!

Hi jpaana

Nice to know that it should be possible to make it work :-D

Can you elaborate a little on how you've configured both the linux system, as well as X2Go, and how you use it...

I guess you are connecting to a virtual desktop i.e. screen :50?

Regards
Anders

Hi Jasem

So I've only seen problems with starting KStars, when connected to a virtual desktop (:50) via X2Go, I also had the excact same issues when using TightVNC.

Since I'm not a regular linux user, I not sure which apps are K-type or X11-type... can you suggest some that I could test with?

I haven't tried noVNC, but from what I understand, it relies on X11VNC or TightVNC as a backend... and since TightVNC doesn't work (as it dosn't allow connecting to the root display ':0', i.e. same issue as what I'm seeing on X2Go), I wonder why it should be better than using X11VNC with f.ex. the Remmina client?

Just some extra info, when I try to launch KStars (from a terminal) on a virtual desktop using X2Go or TightVNC, it complains just like I wrote in my first post, but in the end it issues a Segmentation Error... don't know if that is of any help.

The X11 connection broke: Unsupported extension used (code 2)
XIO:  fatal IO error 11 (Resource temporarily unavailable) on X server ":50"
      after 6 requests (6 known processed) with 0 events remaining.
Segmentation Error

I must say that I think it would be VERY VERY BENEFICIAL for a lot of people in this community, if we could get KStars to work running on a virtual desktop! As X2Go has a fantastic performance!!! It quite literally performs like you are sitting on the local machine... almost no lagging at all... no jpeg compression artifacts... its simply just works like a remote desktop ought to be working!

If I enable the XU4 to boot into the GUI (Mate desktop), then X11vnc works fine.... but the performance of it is awfull...

Hi Pontius

The sensor questions in their spam blocker, can be a bit tricky, especially if you get one of them wrong... then the site won't let you complete even after you've corrected the error... unless you reload the page... It must be an error in the webserver...

Hi

I'm in the process of setting up KStars on an Odroid XU4 running Ubuntu Mate 16.04 LTS.

The idea of this system, is to run everything locally on the XU4 board, and then just connect remotely using something like VNC.

Everything works fine if I run KStars locally on the board, or if I use X11VNC.

I however need the system to be able of running on the XU4 in headless mode, therefore I have disabled booting of the GUI (X-server).
I haven't been able to get X11VNC to work, when the system is running headless (without a screen), and the performance of both X11VNC and
TightVNC isn't very impressive either....

So instead I tried to use the X2Go server/client system... and I must say it's extremely impressive, the performance is fantastic!
And X2Go also support disconnecting and re-connecting to the same desktop instance, as well as physical screen sharing (remote-desktop) if that is needed.

I just have one little issue, I'm not able to launch KStars... when I try to do so I get the following error message:

The X11 connection broke: Unsupported extension used (code 2)
XIO:  fatal IO error 11 (Resource temporarily unavailable) on X server ":50"
      after 6 requests (6 known processed) with 0 events remaining.

Hi jasem

Thanks a lot for your input. I also had been looking at bit at libusb!
I'll begin to read up on the USB protocol and look into how linguider uses libusb for the QHY5/6 cameras, then if I can find the spare time, I'll try to do the development :-)
