Zoom stopped working on Ubuntu 14.04 after nvidia update

brucehvn

I use zoom (http://zoom.us) pretty much everyday for my work. Zoom is a qt app. A couple weeks ago, there was some kind of nvidia update to my Ubuntu 14.04 installation. Now Zoom only brings up blank windows. Their support has pretty much given up and thrown it to me to figure it out. First of all, here is the info they gave me about their application:

We are using Qt 5.6.2 for development. 
Zoom linux client is a Qt Quick application, and its UI part, QML scene graph is all accelerated via OpenGL.

The application seems to work normally except all the windows are blank, so you can't see what to do with it. Here is the output from me running their app at the console:

OpenGL appears to be fine. I can run the gears sample app and the only app I seem to be having trouble with is Zoom. Their support had me install qtcreator and when it comes up it seg faults and the output looks similar.

I appreciate any help someone can give me to get this resolved. In google searches, I've seen examples of this related to python qt apps, but Zoom is not using python at all that I can see. Per their support request I've also tried re-installing the video driver (Nvidia 304) and that went fine with no errors.

Hi, and welcome to the Qt forum!

That's most likely a problem with the Nvidia driver. Why are you using the legacy driver? According to Nvidia's website your graphics card is supported by the latest unified driver, which is version 375.20 at the time of writing. I strongly recommend to update the driver and I'm almost sure the problem will vanish then.

Hi Wieland,

This was just an automatic update from Ubuntu. I didn't install the driver myself. I think there was some message that came up about the driver when it was updating, but I don't remember what it said.

I checked the repo and saw there was a nvidia 340 package and installed it. That seems to have installed version 367 of the driver and now the Zoom application is working again. I don't know what happened before or if the automatic update downgraded my driver somehow, but at least now it seems to be ok. Thanks for the help.

Great :-)
