[Linux] no QtCreator window after installing QT5.3.1

SGaist

Hi and welcome to devnet,

What do you get if you launch Qt Creator directly from the console ?

Hallo!

Thank you for the reply and the welcome.

I simply get nothing.
No window, no error message on the calling xterm and no return to the shell.

Running with LIBGL_DEBUG=verbose does not print anything more than that nothing printed without.

I have checked 5.3.1, 5.3.0 with qtcreator not showing anything.
Version 5.0.2 seems to work.
I did not yet check the versions between 5.0.2 and 5.3.0, this is something I can check tomorrow.

Do you have any hint on how to locate the problem, what to look at?

Saluti!

What's the exact OS you are using ?

Hallo!

I am running Debian (jessie) Linux:

ludwig@oehhp14d:/mnt/nts-projects/Qt5.3.1/Tools/QtCreator/bin$ uname -a
Linux oehhp14d 3.14-1-amd64 #1 SMP Debian 3.14.9-1 (2014-06-30) x86_64 GNU/Linux

Can you try again with the welcome screen plugin disabled ?

Hallo!

In the meantime, I have tried different QT releases from 5.0.2 on.
Apparently, 5.0.2 is the last one which works on my machine.

Starting qtcreator without the Welcome plugin does not change the result.

ludwig@oehhp14d:/mnt/nts-projects/nts/qt/Qt5.3.1/Tools/QtCreator/bin$ LIBGL_DEBUG=verbose ./qtcreator -noload Welcome
^C

Question: what did change in QT 5.1.0?

SalutI!

Hallo!

Today, I have tried to run qtcreator with different backends.
Not one of the backends works as desired:

abort with error messages (initialization failure, blabla)
runs with error messages
runs without error messages

The summary:

eglfs: ABORT -> no /dev/fb0 device, no EGLConfig
linuxfb: ABORT -> no framebuffer device, no screen initialized
minimalegl: ABORT -> no EGLConfig
minimal: RUNS WITH NO WINDOW -> plugin does not support "createPlatformOpenGLContext()" / "propagateSizeHints()"
xcb: RUNS WITH NO WINDOW -> no error message at all

Is it possible minimal/xcb need some EGL setup or other runtime library which is not available on my systems and not identified by glxinfo?

Reinstalling the application may fix this problem.

What desktop environment/window manager are you using ?

Hallo!

I use a traditional icewm on three boxes, all showing the same behaviour:

amd64 / nVidia
amd64 / intel
i386 / ATI
