Thanks for being patient and explaining. My goal is to have decent performance for 2D and 3D across two 1600x1200 monitors with the M22 X300. - Putting them side by side at 3200x1200 works fine for 2D but runs past the 2560-column limit for 3D. - Turning the monitors to portrait mode and putting them side by side doesn't work because rotation is not accelerated without EXA, and, even with EXA, the whole desktop is too big to rotate with a single texture. - Putting the monitors one above the other in normal landscape mode might work, but is at the moment mechanically infeasible. - The only remaining possibility would seem to be using Xinerama with two different frame buffers, one for each monitor, but I seem to recall that hardware-acclerated 3D won't work in this mode. Perhaps it's time to give up. :^( Unless anyone has an idea of how I might reach my goal, I'll sign off now. Thanks for your prompt and generous responses. :^) -- Thomas E.
