I’m involed in developing some Qt application build under Linux. I have downloaded the source code and compiled it under Windows 7 firstly, but then I decided to work under Ubuntu. The problem is, the application in Linux looks like in Win95 times. I have installed Qt4 Settings and chosen GTK+ style, but this improved the look only a little bit, though it still looks very ugly (like 256 collors pallette, font is italic). I have also installed many gtk libraries, but nothing helped. I use Qt-4.7.4. I know that it should look different, beacuse on Windows the problem doesn’t appear, even on my boss’ computer, who is also using Ubuntu, the application looks much better.

The app changes style to QPlasticStyle itself.

Thanks in advance for every answer.

Well, another lot of tries, but nothing changed. Maybe I will show you the problem. How the app should look like (more or less) (ss made by one of my co):

and how it actually looks like (ss made by me):

There are two things that I haven’t done so far:
1) At the beginning, I installed Qt-4.8.1, but it was generating some OpenGL errors with make so I then downloaded 4.7.4 version (the one that my boss and cos are using) and was strugling with installation. Finally, I just overwrote qt-make from 4.8.1 with the one from 4.7.4 and it compiled fine. But then I encountered the ‘Question thing’. The point – all Qt applications tells (Help-> About Qt) that they are using Qt-4.8.1 and I wonder if it has some connection with the problem.

2) Second thing is my graphics. I have MSI CX640 notebook with Nvidia Optimus on board. After installing Ubuntu I had to make it using the integrated Intel HD3000 instead of the dedicated GT520M (it was making the fan behave noisely unnecessary). I have googled for the way to do so and actually succeded in disabling GT520M. What is the point of it – I’m not sure, but I remember some OpenGL things were mentioned on sites where I was searching for the solution). I think this has nothing in common with the problem, but I’m so frustraded tha now I’m insighting everything.

Maybe these can give better overview of the problem.

PS. Thanks for your attemps, I appreciate them.

    Well, few days have passed and I’m still struggling.

    But, I have reinstalled properly Qt 4.7.4 and, if build on it, the application looks good, despite of font, which is like Monotype instead of Ubuntu’s one.
    Unfortunately, this is Qt issue and is hard to compensate it. Maybe you now how to do that?
    I’m on the last part of way to solve my problem.

    EDIT: Hurray! Solved!
    I stacked with 4.8.1 made compatible with my project with use of
