Waveforms on Linux hangs on select device.


RTC

Question

Just installed Waveforms for Linux (3.12.2 64-bit Qt5.6.3 Linux Mint 18.3) and it hangs on opening device.

Is there a driver missing? A reboot did not solve the issue.

 

Thanks!

Hi @RTC

It is working for me with Mint 18.3 64bit Cinnamon.

On Linux the 'open device' window may remain on screen after successful device connection. This needs to be close (X) this manually.
I was not yet able to reproduce this consistently to be able to solve it.
Is the app/device working after your close the progress window?

Try launching the wavefroms from terminal to see if there are any warnings or hidden errors printed.
The SSL warnings are expected:

You can run dmesg to see the last system messages.
For me only the follow normal device connection events are listed.

No output from command line.

If DDiscovery is plugged in when Waveforms starts, the 'Opening device' dialog comes up and hangs. Dismissing it crashes Waveforms.

If it's not plugged in, the device manager dialog comes up.  On plugging in, the device with serial number comes up. Selecting it then brings up the opening device which again hangs. Dismissing opening device takes me back to the device manager dialog. Then cancelling the device manager crashes Waveforms, sometimes, anyway.

With no device plugged in, starting Waveforms and selecting demo does work.

Running Mint 18.3 x86-64.

Not a big deal for me,  I can run using Windows.

Didn't see anything that popped out to me from dmesg (below is typical).
