QTCreator does not start: Could not initialize GLX

henkman

Hi,
I installed Qt 5.8 with QtCreator on Ubuntu 16.04 with a NVidia GTX1050i card and nvidia drivers installed. GLX version 1.4 seems to be running as shown with glxinfo.
The issue is that when I start qtcreator from a remote ssh session that it won't start.
I get the messages:

Could not initialize GLX
Aborted core dumped

So far i haven't found any solution how to solve this issue.
Any help is appreciated

@henkman Try to start it once from terminal with "-noload Welcome" parameter. If it helps go to Help/About Plugins..." and disable Welcome plug-in there.
See here for more information: http://doc.qt.io/qtcreator/creator-faq.html

Hi jsulm,

Thanks for your response. That was one of the things i found on the internet but unfortunately it does not seem to work for me,

I also tried these :
-noload Welcome -noload QmlDesigner -noload QmlProfiler

No succes at all...

regards
Henk

@henkman "remote ssh session" - that one I didn't see. Does QtCreator start properly locally?

Hi,

Are you also doing X11 forwarding in your remote ssh session ?

I logged in using "ssh -Y hostname" and started qtcreator 4.4.1 with the options given above, but this does not help:

[ch720-01:~]$ qtcreator -noload Welcome -noload QmlDesigner -noload QmlProfiler
Could not initialize GLX
Aborted (core dumped)

I can open an xterm or gnome-terminal, but qtcreator fails.

Looks like it might be related to QTCREATORBUG-14998.
