I'm running RHEL4 at work on a Dell 690 with an Nvidia Quadro FX 4500. (64 bits, but I don't think that makes a difference in this case.) I also run FC2 on a Dell 670 with an Nvidia Quadro FX 4500. Two different people built the two different loads.
I'm running a visual task that requires the screen to have 8 stencil bits available. The 670/FC2 runs correctly and reports 8 stencil bits. The 690/RHEL4 runs incorrectly and reports 0 stencil bits. The two people who built the different loads have no idea what difference caused this problem and have thrown up their hands.
Anybody have any suggestions?
