Hi all,
I'am using the last version of Qt (4.7.3) on Ubuntu 10.04 machine. The pc has a intel i855GME graphics chipset. When configuring Qt via configure script I give it the option "-graphicssystem opengl" and "-opengl desktop". The configure script report the following lines:


Build type: linux-g++
Architecture: i386
Platform notes:

- Also available for Linux: linux-kcc linux-icc linux-cxx

So I think that openGL support was enabled, but when I run some application the first line in the output is:

Anyone have experience the same problem???
