Hi,
Having installed KStars with EKOS last version under Ubuntu-Mate 15.10 all is working fine. I am able to connect to the RPi2 running the indiserver with the drivers for mount and ZWO ASI 120MC.

The buttons on the screens in EKOS do not all show their graphical icon, some do.
Have a look to the attached screen-shot I include.
The panel on which I can slew my mount in the different directions has empty buttons in the positions: N, S, E, W and Centre. At the corners one sees the arrows. It is self explaining what these buttons with missing graphic icons mean and I do not know what to expect there, but it seems there is something missing at the level of the themes loaded in KSTARS.

It is more disturbing in the case of the ZWO ASI cam and the EKOS control screen, or the Scheduler tab.
See the second picture attached. Icons are missing on the top right series of buttons. Here it is totally unclear what the buttons do.

Any idea how to overcome this issue?
Thanks a lot!
Stefan

I found in the mean time a post about this subject on the forum.
www.indilib.org/forum/ekos/967-rpi-ekos-...e-no-icons.html#6339

I tried it out without result.

Check again here: www.indilib.org/forum/ekos/967-rpi-ekos-...ns.html?start=6#7099

Sorry, I tried what suggested in the above link but I still missing icons. I use Kubuntu distro ...

Kubuntu? Are you sure? which version? KDE based distros shouldn't have a problem with this.

Sorry, my mistake: xubuntu 15.10 with xfce 4.12

I'm using Kubuntu and also missing some button icons. Jasem you can see them missing in those moravian screenshots i send you.

I am testing rp3 ubuntu-mate 15.10 and same problem for me.didn't work for me.

I followed the steps here to install qt5ct:
fixmynix.com/change-qt5-application-style-with-qt5ct/
(latest version is qt5ct-0.23.tar.bz2)
build the package and configure once in qt5ct

and then run kstars at terminal with: QT_QPA_PLATFORMTHEME=qt5ct kstars

and the icons pop up right
I'm using ubuntu server 16.04 with vnc

I have now upgraded my OS to Ubuntu Mate 16.04 on RPi2.
Most of the buttons now have icons visible. Here and there an icon is missing.
Huge improvement, Great!!!!

Hi, I am running Xubuntu 16.04 and had the same problem.
After digging the forum nothing worked.

Installing this library "libqt5libqgtk2" solved the problem.

sudo apt-get install libqt5libqgtk2

I checked again and without any other manipulation all icons are no present on the buttons.
Also the new feature allowing to create profiles before launching and connecting the indi-server to devices works very well.

In order to repeat, I just upgraded to Ubuntu-Mate 16.04 and installed kstars-bleedingedge and it is all OK.
