Just discovered these messages in /var/log/messages, while looking at the USB problem I just posted about, separately. Apr 27 20:23:16 fcshome kernel: NVRM: API mismatch: the client has the version 331.67, but Apr 27 20:23:16 fcshome kernel: NVRM: this kernel module has the version 331.49.

Please Apr 29 19:22:30 fcshome kernel: NVRM: make sure that this kernel module and all NVIDIA driver but I cannot find anything relating to Nvidia that has a 331.49 version number. "yum list installed | grep 331.49" returns no hits "yum list installed | grep 331.[0-9]" returns ONLY hits on 331.67. "find 331" finds lots of things, but none of them is 331.49. So, I'd be appreciative if someone could shine a light on this for me. thanks! -- ---- Fred Smith -- fredex at fcshome.stoneham.ma.us ----------------------------- Show me your ways, O LORD, teach me your paths; Guide me in your truth and teach me, for you are God my Savior, And my hope is in you all day long. -------------------------- Psalm 25:4-5 (NIV) --------------------------------
