1441384 - Getting Vidyo working on Fedora 26-29

Status: RESOLVED WONTFIX

Description

Hi, I just joined Mozilla. Today I reported (via Nestor) that I could not launch VidyoDesktop on Fedora27 with the following error:


QGtkStyle was unable to detect the current GTK+ theme.
CLIENT: socket_error 
removed server QTVD-IPC-SERVER

However. I've been able to resolve it and thought it was worth sharing in case others have the same problem.

The problem appears to have been a lack of a system tray. Installing the TopIconsPlus gnome extensions fixes the problem. https://extensions.gnome.org/extension/1031/topicons/

One more thing to add. I cannot get the latest version of Vidyo available for linux (3.6.3.017) to work.

I have to use 3.3.0.027, which I found here: https://v.mozilla.com/upload/VidyoDesktopInstaller-sl564-TAG_VD_3_3_0_027.rpm

And then make sure it does not upgrade.

The error I get for 3.6.3.017 is:

QPainter::begin: Widget painting can only begin as a result of a paintEvent
Object::connect: No such slot VDCallWindow::OnHideMuteToolbarsWhenWindowDeactivate() in ../source/VDController.cpp:3847
Object::connect: (receiver name: 'VDCallWindow')
/usr/bin/VidyoDesktop: line 6: 4178 Segmentation fault (core dumped) /opt/vidyo/VidyoDesktop/$EXEC $option $audioflag $@

and I didn't find a solution for that.

FWIW I have this same problem on Fedora 26.

[Emilio Cobos Álvarez [:emilio]]

And Fedora 28 too :)

Comment 4

[Andrew Halberstadt [:ahal]]

Thank you, the workaround works great!

If we can't actually get Vidyo to fix the issue upstream, could we at least roll the version offered by https://v.mozilla.com back to 3.3.0.027 by default on Fedora?

Bug 701083 comment #128 is as far as I got with Vidyo 3.6 and Fedora.  (I use Debian, but I tried a few other distros in VMs to see if I could help people out.)  If I recall correctly there was clearly a bug in Vidyo's code causing that crash, but I couldn't easily see why it would break on Fedora but not Debian unstable (which both track upstream releases relatively closely).

Comment 6

[Andrew Halberstadt [:ahal]]

Upgrading to Fedora 29 broke vidyo, even with TopIconsPlus and the older vidyo installed. The error I get is:
> VidyoDesktop: error while loading shared libraries: libidn.so.11: cannot open shared object file: No such file or directory

I tried installing the 'libidn-devel' and 'libidn2-devel' packages, but same thing.

Comment 7

[Andrew Halberstadt [:ahal]]

Turns out I have libidn.so.12.6.0 on my system. I tried manually creating a link called 'libidn.so.11' which gets me a little further, but VidyoDesktop then goes back to segfaulting with the same error in comment 1.

Comment 8

[Andrew Halberstadt [:ahal]]

Success! The latest version of TopIconsPlus was the culprit. I tried using TopIconsRedux instead and now I have it working again. To recap, here is the (ever growing) list of things I had to do:

1. Install the old version of Vidyo here: https://v.mozilla.com/upload/VidyoDesktopInstaller-sl564-TAG_VD_3_3_0_027.rpm
2. Install the "TopIcons Redux" shell extension: https://extensions.gnome.org/extension/1497/topicons-redux/
3. Manually symlink libidn:
$ cd /usr/lib64
$ ln -s libidn.so.12.6.0 libidn.so.11

Then it started working again.

I had delayed upgrading to 29 for other reasons. Vidyo was broken in the same ways described after updating and following Andrew's steps worked to fix it for me.

Comment 10

[Sarah Bird]

Just did a fresh install of Fedora 29, and needed to run the following: sudo dnf install mesa-libGLU

So, to recap, with Andrew's instructions:

1. Install the old version of Vidyo here: https://v.mozilla.com/upload/VidyoDesktopInstaller-sl564-TAG_VD_3_3_0_027.rpm
2. Install the "TopIcons Redux" shell extension: https://extensions.gnome.org/extension/1497/topicons-redux/
3. Manually symlink libidn:
   $ cd /usr/lib64
   $ ln -s libidn.so.12.6.0 libidn.so.11
4. Install libGLU:
   $ dnf install mesa-libGLU

With the switch to zoom, I'm going to close this.
