OpenGL drops me to clone mode!
Running SuSE 9.2, Athlon64 3500+, Radeon 8500SE (not incongruous at all).
I have it doing dual head via MergedFB, and it works perfectly, but when I run anything that uses GL, it pops the second head into clone mode. If I kill the program, switch to console and switch back, it returns to its normal wide desktop goodness. I can understand the popping to clone mode, but I've never seen behaviour like that in all my years of unixing. Any ideas what's causing it? Any ideas how to make it go away?
