Hi
Try to update the gfx driver.
Seems Qt is not able to go accelerated.

Mikeeeeee

I installed all graphics card drivers.
What is the minimum OpenGL for QT to work?

mrjj

@Mikeeeeee

Hi
seems to be 2.1
http://doc.qt.io/qt-5/windows-requirements.html

Can you test with anything else than Qt if openGL works?

Mikeeeeee

The program "OpenGL Extension Viewer" says that OpenGL 2.1 works.

mrjj

Hi
Well, it does look ok number wise.
Is catalyst 8.5 really the newest you can get ?
(from 2008)

Mikeeeeee

Yes, this is the newest driver (from 2010).

@Mikeeeeee

Hi
Is the Radeon Xpress 1150 the only graphics card there is?
i mean laptop do not have other one?

For some reason Qt do not like the openGL, it seems.

Do you need to use QML ?

Mikeeeeee

The video card is the only one.
Yes, me need to use QML.

Hi
Please see here
http://www.sanchitkarve.com/blog/category/how-tos/
section
Use ATI Radeon Xpress 1150 Graphics on Windows 7
says "Moral of the story: DO NOT install version 8.593.100.0 !!!"
which might be the version you have ?

I would try an older driver like mentioned in the article.

Mikeeeeee

But the test shows that the driver is working fine.
Surely other tests will show that the driver is working.
The point does not seem to be in the driver.

Hi
Did you try to run a game or anything that needs good
acceleration?

It seems Qt (QML) cannot create a context so something is not
working as expected.

Mikeeeeee

I did not run the games.
But what then are the minimum requirements for Qt?

mrjj

@Mikeeeeee
Well, link says openGL 2.1 but is a bit vague on shader model and extensions needs.
At work i had a laptop with intel 4000 HD gfx and even it listed correct openGL version
QML would still not work.
Just to be sure. You just use the laptops screen, no external screen via USB or anything like that?

Mikeeeeee

Yes, I can just use the laptop screen, so it works. But usually I additionally connect another monitor.

Mikeeeeee

Maybe you need to configure QT?
Or instal emulator newer OpenGL?

@Mikeeeeee
Hi
Well i had issue with a DisplayLink device as it would prevent
anything accelerated so thats why im asking.

In any case, i wish you would try to run something game-like and
if that can run , open bug report.

Mikeeeeee

I tried to run the game.
STALKER 3 started up and worked fine.

Hi
The openGL version ?
it can use both DirectX and openGL.
Anyway, if you feel 100% sure you have tested that
openGL does work
as expected on your pc.

You should go to https://bugreports.qt.io
and open bug report.
For QML and Radeon Xpress 1150.

The answer might be its simply too old. but its worth a shot.
