When I debugged my crashes, I found that there were 2 problems causing them:
1) 'BackingStore' option in xorg.conf causes crashes when switching user every time.
2) OpenGL applications (glxgears, googleearth) cause Xorg to crash every-time when overriding FSAA settings in nvidia-settings. To fix this, I added the 'UseCompositeWrapper' option to my xorg.conf and I can now use FSAA.
