Dear all Thanks for your input. With your help, I just installed the stereo on linux with two monitors using the clone mode. The coot and pymol stereo work beautifully. But I met some problem, every time I walked away from my computer to do some real work, the screensaver would be activated and I couldn't log back on. So I lost some part of my work. The virtual console Ctrl+Alt+F1~F6 worked. I tried to use kernel-devel to build the nvidia driver both the certified 190 version and the beta version 195.22 and 195.30. But none of these versions could correct the error. When I allowed the certified 190 driver to write the xorg.conf file, it worked. I googled it, but didn't find any answer. Has anyone encountered the similar problem? Thanks for your help in advance.
