Hi,
I try to write a program for such a device Uniq-POS 55.02 [unisystem.kiev.ua].
I plan to use it on Linux.
And all I test on precompiled Qt5.0.2
But faced with the following problem that occurs – under linux (I tried Ubuntu 12.4 and calculate linux (a descendant of Gentoo)) i see a very heavy load on the CPU and the slow implementation of the animation. As an example for testing I use the standard example – “interaction” and animation when I press the button takes a few seconds.
I tried Windows 7 – all works well.
I understand from the forums that the problem likely is in the support of OpenGL, but in linux I see the following:
glxinfo | grep direct:
direct rendering: Yes
(and the video card is recognized by lspci)
00:02.0 VGA compatible controller: Intel Corporation Atom Processor D4xx/D5xx/N4xx/N5xx Integrated Graphics Controller (rev 02)
Can you please tell me which direction to move further
↧
