[CentOS] kde failing???

And yes, it acts just like keyboard input. I don't have the model numbers handy, but I do believe one was a Symbol-brand scanner (colors in photos look about right). -- ---~~.~~--- Mike // SilverTip257 // ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

TIA Rob Later versions of kmod-nvidia are for EL7.3 (not backward compatible). You need to update your CentOS system using the CR repo. Or wait until the full release of CentOS 7.3.1611 (next week?). Ahhh - no problems, I'll await 7.3 and exclude kmod-nvidia for now.
