When I tried to install ROS Noetic on Ubuntu 20.04, I have a little problem about dependencies. So I used sudo aptitude install ros-noetic-desktop-full and I downgrade some library (I forget which libraries I downgrade). When I tried to run rqt_graph, the buttons on the window don't show icon image. When I tried to rum rqt_console or rqt_logger_level, the buttons on the windows don't show icon image. (Sorry, I can't include images because need > 5 points).

I tried to uninstall by sudo apt-get remove ros-* and install ros-noetic again. But still doesn't change anything. What should I do about it?

I have the same issue, with all of the rqt plugins (rqt_bag, rqt_plot...). Have you had any luck? I am still able to use the plugins by hovering my mouse over the buttons, so the hint shows what each button does.

I found something that works for me! First, I made sure that the tango icon theme was installed sudo apt install tango-icon-theme.

Then, I was searching through all of my installed apps for icon settings, and I found an app called Qt5 Settings. It has the option to set the icon theme, so I set it to tango and hit apply, and now the icons show up for all of the rqt plugins! I hope that works for you!

Thanks, that seems to work! I'm using the osrf/ros:foxy-desktop docker image and was able to fix this problem there by sudo apt install qt5ct, export QT_QPA_PLATFORMTHEME=qt5ct then choosing the tango theme in the qt5ct application.

If anyone knows how to set the icon theme in the docker container without qt5ct, please share!

When I open Qt5 I cannot select Tango. It shows up but if I click nothing happens. How did you select Tango in the "Icon Theme"?

I think problem is in PyQT. Try to create a "hicolor" symlink that points to the tango theme. It works for me (I run rqt in docker container). This advice from https://www.pythonfixing.com/2021/12/...

 ln -s /usr/share/icons/Tango ~/.icons/hicolor
