Matrox has released version 1.4.3 of their driver for the Parhelia and P650/P750 graphics cards on dec. 15. The new driver is not called a beta anymore.
It supports Linux up to 2.6.14 and XFree86 4.3 or X.Org 6.7.0 “or later”, and features the new TripleHead Independent (THI) mode that allows to set different resolutions and refresh rates for the displays.
– Some OpenGL based game engines do not work (ie. UT2003, UT2004) properly with this release and may crash or cause display corruption.
– Screen corruption may appear while using Blender.
