[SOLVED] QtQuick won't start (or starts with blank screen) due to grafic card

SlimIT

Hi,

i have a QtQuick applications that is built on the Qt 5.1 (with Layouts & Controls). My app works fine some computers but don't work on others ( The previous app version (Qt5.0.2) works good on all these computers ).

I have noticed that because the new version won't start on a computer which have a (Mobil Intel(R) 945 Express Chipset Family) and when i removed the driver the app works but there is a blank screen. I have also reinstalled the driver and maked some change to make it work with the driver but there is also a blank screen.

Notice: The application works good with the blank screen when i click on some buttons but i don't see nothing.

Can you help me please ?

Thank you.

Which platform is this? If it is windows, you could for instance try using the angle builds which have more reliable graphics drivers.

SlimIT

It is windows and i can't find an angle build for Qt 5.1.

Someone adviced me to try compiling from source so is that simple & have you a good wiki for that ?

Thank you.

Jens

The angle build is simply the precompiled packages that do not have -opengl in the name.

SlimIT

For Qt 5.1 i don't find a mingw precompiled package without *-opengl *in the name. And i don't have an MSVC Licence.

Is MSVC included within the precompiled package ?

JKSH

No, the Qt Project cannot include MSVC for legal reasons.

However, you don't need an MSVC licence -- you can download Visual Studio Express for free from Microsoft. Or, if you don't want the Visual Studio IDE, you can download the Windows SDK, which contains the same compiler.

SlimIT

Thank you.

I have installed a Qt 5.1.0 version with MSVC 2012 and without opengl.

I have also installed Visual Studio Express 2012 and configured the compiler with Qt Creator.

Now the application works but still the same problem i have a blank screen and the application and i can't click the buttons that i know the emplacement as in the MinGW version.

Have you an idea ?

SlimIT

The application works now.

I was opening the application through a shared folder on the network.

After i have copied it to the computer it works good with the MSVC version without opengl.

I have also copied the MinGW opengl version but it has the same problem (blank screen).

So the problem was really due to opengl.

Thank you.
