Hello, Just finished installing Centos5.1 on two machines (P4s, Nvidia graphics, Gnome desktop) Running OpenGL applications and need to run in full screen mode without any frame borders or window icons across multiple monitors. ( 4 monitors with two dual-headed Nvidia cards in twinview mode ) One machine works just fine, the other retains the Gnome frame and opens the apps in an X-term window. Have compared the X11 startup files, Xsession, scripts, Gnome settings, and can't find any differences. Obviously, I'm missing something, somewhere Under Debian things work just fine. Sure I'll eventually find it, but any help would be appreciated. Also is there anyway to turn off the update popup window? Not to cool when it shows up on the game screen.... Thanks John
