@Wieland I use a NAVIDA k1000 ,dell M4700 MOBILE work station. I download a gui management of nivida, so I think it should not be the problem.

@dennile
oh, its a Core i7 CPU ?
Should have plenty of power. even for BOOST. -
@mrjj yes, it is the high configuration at that time. Let me change to another computer to check whether it is the problem of computer, and then give feedback to you guys. Anyway, thank you firstly!

hi, all guys, I think the problem should be the system linuxmint, which is a variables of linux. When I change to a common apple computer, it is very fast. I do not know what is the mechanism the linuxmint affects, maybe the QT, maybe the performance of my computer, so I am just sure it is not the problem of QT. Thanks, everyone!
-
ok.
Just as a note. I run linux mint at work.
I switched to it after they made ubuntu use unity
and not have had any issue with Qt on mint. -

@mrjj Your answer makes me confused again, if that, so what is the problem? Whether some of configuration I do not do rightly? or, it is the problem of my computer? So how to make sure the driver is correctly configured? How to evaluate the performance of computer?

@Wieland how to make sure I install a correct graphics driver?
by the way, my graphic card is Quadro K1000M, -
@dennile Sorry, I can't help you with your Linux distro, that's not my field of expertise. But I must say that the graphics driver (be it the proprietary Nvidia or Nouveau or drivers for Intel GPU) are the only source of real trouble I had with Linux in the last maybe 7 years or so.
