hi friends,
I am having a qt application having more pixmaps in graphicsview, so the X lib is shooting to 25 to 30 % and some time 100%.
i tried -graphicssystem raster as flag along with the executable and it reduced to considerable amount of 5% in ubuntu with 4.6.2 version of Qt.

but when i try the same in RHEL with Qt version of 4.4.3 -graphicssystem is not working.

please help me...

What is the problem?

You used the graphicssystem command line option, which was introduced at Qt 4.5 (http://labs.qt.nokia.com/2008/10/22/so-long-and-thanks-for-the-blit/), with Qt 4.4.3 and it doesn't work. There's no mystery here.

is there any other method so i can reduce xorg consumption in qt4.4.3 or else only option is to upgrade to qt.4.5

You can replace the CPU in the machine with a faster one :)
