OK I saw this fragment in a previous post by Ben.
I didn't do anything special accept for run 3Ddiag which told me to run the right switch2* script in /usr/X11R6/bin. I played Soldier of Fortune in all it's glory lastnight for 4 hours .. it worked fine. Heavy Gear 2 hasn't looked better then it does with 7.1+4.0.2.
Now my 3D works fine. It appears you must run: /usr/X11R6/bin/switch2nv_glx However if I attempt to run the GL screensavers they all crash. If I use: /usr/X11R6/bin/switch2mesasoft The GL screensavers work fine. My questions are: 1) Can I permanently enable /usr/X11R6/bin/switch2nv_glx by putting it in a config file somewhere? 2) Are /usr/X11R6/bin/switch2nv_glx and /usr/X11R6/bin/switch2mesasoft mutually exclusive? Thanks in advance -- Cheers, Jonathan
